world-optimization

[gentle gust]

a world usually can go higher material wise and tris wise than an avatar

[strong loom]

True but what would be a good estimate to work towards

since im planning on optimising some stuff later on when im done building it

[lilac saddle]

anyone know if Occlusion Culling works with VRC Worlds?

[untold apex]

yes

[lilac saddle]

nice, thanks for that wasn't sure didnt see it on the VRC SDK website

[gentle gust]

it really depends too much on the type of world, layout, artstyle etc to say

[strong loom]

i pretty much based it on this reference image and went from there

the gist

simplicity and small abstract furniture

[gentle gust]

the best way to test is upload -> see if you can hit 90-120fps in VR everywhere you look

[strong loom]

Good Point

I will cobble it together and see if it works out once i made some progress

[strong loom]

i get over 100fps on desktop.

testing it in vr in a bit

i noticed later that some normals are inverted on the bed mesh

[strong loom]

i tested in VR. I got about 110 fps in every area. With a Friend it hovered about 60 FPS

[gentle gust]

shoot me the link to the world (can be private) and ill check it out myself if you want and tell you how it runs on my end

[strong loom]

sure

the baked lighting is a bit scuffed but i will try to fix that later

its still heavily wip

[raven zenith]

What's the recommended texture resolution for objects?

[untold apex]

it's entirely dependent on the object's size, how close you can get to it, how much detail you need, etc. generally the smaller you can get away with, the better, since textures usually make up the largest part of the download size for a world

[lofty musk]

Hi all! I read in the VR Chat developer documentation that it suggests to avoid having 3 video sources in one room as it can cause issues. I tested and verified only one of the 3 works. I was really hoping to have it to at least appear to have another TV with a looping animation next to the original which has Wolfe video player on it. Any suggestions?

[hybrid ridge]

Have the first video load on start and loop, so it loads initially and doesn't interfere with the others

100% do not recommend

If the animation is simple enough do a spritesheet animation

[lofty musk]

Alright I will try the sprite sheet - I was able to create a sprite sheet using ezgif.com - Is there a tutorial or video you would recommend for the remainder of the process? Thanks!!

[hybrid ridge]

Honestly not sure on the actual execution, it should be the same as a normal sprite animation with a sprite sheet

Its probably a unity sprite tutorial

[lofty musk]

Thanks 🙂

[lofty musk]

Thanks, I was able to get it working using animated sprites! I even learned something new!
The key is to click the png and change type to sprite

glad to be of help

[gritty roost]

anyone know how i can make the lighmap not take up 128mb?

but also have the lighting not be horrendous

nevermind apparently its 300mb now

i have no idea what to do

hoping to get the entire world to hit 100mb or less

[unkempt summit]

download https://github.com/oneVR/VRWorldToolkit so you can get a breakdown of each asset size

if you want to reduce size, an easy way is to reduce the resolution of images. There might be huge normal maps, lightmaps

[pallid gale]

I suppose you could lower the Texel density on the lightning as you wouldn't want to use values intended for indoor maps for a large outdoor map

[gritty roost]

i use that

[unkempt summit]

then you can tell what the largest assets were

[gritty roost]

theres an indoor scene as well

[gritty roost]

i do know tho

the ligthmap

i wanna know how to generate a smaller one

that also looks okay

[pallid gale]

as I said lower the textile density on your lighting

[gritty roost]

yea ill try that

[pallid gale]

https://www.youtube.com/watch?v=dKgUJccjWRU

[unkempt summit]

https://docs.unity3d.com/uploads/Main/Lightmapping-0.jpg

lightmap size

[pallid gale]

you would want the lightmap resolution setting because lightmap size would just dictate the max size a light map can be before you make a new one

so reducing lightmap size would just make more light Maps that would probably end up with the same file size

[unkempt summit]

looking at the scene you have a huge plane with plenty of repeated assets, not sure if it works but maybe the plane's lightmap can be set smaller using "Scale in Lightmap"

https://forum.unity.com/threads/lightmap-resolution-v-scale-in-lightmap-object-setting.512680/

[pallid gale]

https://gitlab.com/s-ilent/lightmap-quality-regions

[unkempt summit]

wow cool tool

also, I wish it was possible to have an asset bake a lightmap once and just not refresh it, so I can clone the asset with the same lighting since they are not going to be different

since in that scene, it doesnt look like the lighting changes much for each tower

[pallid gale]

so it looks like the screenshot doesn't have like any lighting besides for the ambient lighting

[hearty ore]

So, I wanna optimize my world by atlasing everything together, but I ran into the issue of needing to extend UVs beyond the image edges to tile it all properly. Is there a way to tile UVs so that I don't have to extend the UVs past the image border?
ex:

[pallid gale]

basically you would cut your geometry into strips that would fit into the 0to 1 https://i.gyazo.com/19f31e422f52fe4a39c5627b44af4d4c.png

of course you would have the pieces on top of the wood I just stack them like that for visual clarity

but I would also note that you could have like a atlas for stuff that tiles left-to-right and a separate list for like uniquely textured props

[hearty ore]

That's what I feared I would have to do. I didn't want to increase my map's poly count too much

[pallid gale]

also wonder if you should worry about the atlas once you actually have more of it done so you know what textures you actually need

[hearty ore]

I'll probably slice the wallpaper I currently have on there into sections to fit other wallpaper colors on there and use the other space for other stuff. I do not want my geometry being more complicated than it needs to be

[pallid gale]

also it's not the end of the world if you have a couple of tiling texture that cover a good chunk of the space

[hearty ore]

The issue comes down wanting to confine UVs to a small portion of the texture and then repeat the texture across the UV length

[pallid gale]

also if it's helpful your textures don't need to stay Square they could be rectangles so you could stack like tiling textures that go left to right on top of each other

[hearty ore]

Oh. Okay then. I guess I have room to spare since my textures are only 512

[pallid gale]

trim sheets are also a quite helpful concept to learn for environment art

[pallid gale]

https://www.youtube.com/watch?v=urrhgBHVYGQ&list=PLHPl0SFKkUjNcC8r3tLFW1-WCdNCAAFjV but if it helps here is a video tutorial on how to shove all of the tiling textures onto an atlas even if that might be a little overkill on a chill bedroom map

[untold apex]

i can't begin to describe how helpful a good trim sheet can be. they take some planning but they will save you so much space

and by some planning, i mean a lot. i screwed up my proportions a few times before i understood how to plan them properly

[pallid gale]

https://www.artstation.com/blogs/finnstevenslock/yd4Q/finns-guide-to-trim-sheets

a pretty nice text guide to trim sheets

[fallow drum]

Yea if you dont build with trim sheets in mind from the start, it can be very hard or even impossible to make them work for you geo if you dont make stuff with them in mind.

[pallid gale]

yup but it is relatively smooth sailing once you actually got the trim sheet set up because you can make like new objects pretty quickly and have them look relatively nice with like hardly any file size or vram as they are reusing the texture

all of the stuff in red in the second screenshot is using trim sheets

[fallow drum]

Completely unrelated but i really like how they put the darker ends on the glass

or maybe thats a specific glass shader 🤔

[pallid gale]

https://vrchat.com/home/world/wrld_b1317301-d8fa-4d49-816e-0a695989342b the world if you want to go explore it and look at some nice trim sheets

[fallow drum]

I really should use them more often.

[pallid gale]

yeah they can definitely help optimization and potentially make your Maps look nicer

[fallow drum]

Still has me wondering about that glass though XD

time to google

[pallid gale]

have no clue about the glass

https://www.youtube.com/watch?v=DipfrjCgYW8&t=2s

[fallow drum]

I'd probably make them in blender + substance

[pallid gale]

yeah that works fine and dandy just sharing tutorials so you have some idea of the general thought process

[lilac saddle]

is there a way to free up space in my world without removing anything

[pallid gale]

first figure out what's taking up space https://github.com/oneVR/VRWorldToolkit

[fallow drum]

^ and once you've used that to find all the big textures, lower their resolution and enable crunch compression on them

[untold apex]

pretty much all of the walls here are a single trim sheet:

[pallid gale]

do you have a picture that shows the trim sheet

[untold apex]

yep lemme grab the texture

this is the AO texture... easiest to see

[pallid gale]

very nice

[untold apex]

it really does take a little work to plan out, but once you get it, it's so helpful in reducing material and texture load. to generate it i just modeled some high resolution bevels and decorative trims, laid them out in a grid, then baked out maps in substance painter.

[pallid gale]

yep that's how one goes about it

[untold apex]

floor tiles, fountain and planters are handled the same way... each group of eight tiles is a square segment picked from the trim sheet.

[pallid gale]

nice

[untold apex]

stuff like puddles and extra detail is just done via the height and roughness maps: you could do huge rooms using this method and never lose texture detail with a single 2k or 4k map.

it's so much fun to set stuff up this way rather than the traditional method of using single tiled materials or just laying everything out by hand

final product's here if you want to see it. https://vrchat.com/home/world/wrld_2e37b570-7f57-46d5-9ef5-e33d1326c70b?__cf_chl_tk=FfzG3joEK_T88VHCRrMgrurcQOKo9bMvEQr5.cHqDAA-1646163326-0-gaNycGzNCf0

[pallid gale]

thanks for the world link

[untold apex]

of course! trying to get more people to see it anyways. if i ever have the time i'm hoping to do a more detailed write-up.

[pallid gale]

yeah that would be cool a write-up

[tawdry spoke]

Anyone who knows how to add music to a world in vr chat? I'm looking for the spotify playlist in Club Ruby

[torn crypt]

vry nice! this was how I navigated base mats w/ VRC stuff for a bit + it worked really well. I eventually decided to go back to using tiling base mats (+ blend mats) though because I kept getting nasty mip bleeding whenever I couldn't be precious about what was on the base mat atlas

Blend mats also ended up being a more scalable way to hit target texel density (at least in my case) because I could just tile material layers as needed which I couldn't do with everything being trims/atlases as it basically became defined by the texture res

[pallid gale]

you could potentially use shaders to Overlay some like stuff on top of the trims

and the typical workflow of trim sheets would still have tiling textures for like walls and stuff

[torn crypt]

Yeah! Trims are definitely helpful for scalable use + maintaining texel res in a lot of case.. Base materials for like walls and those sorts of structures can still benefit from being tiling mats, I think. Maybe not on Quest though because doing layer blends might get a bit expensive

[pallid gale]

don't have a quest myself so haven't exactly benchmarked material blending

[torn crypt]

Same 😅 You'd eat some cost from the extra texture samples + lerps but it might be alright in the end if you offset the overhead by using it to make some sort-of uber material that gets used across tons of stuff

[brave charm]

Can you make see through glass for quest?

[untold apex]

yes, on worlds. but be careful about overdoing it, the quest does not like transparency

[brave charm]

ok

[pallid gale]

it is essentially a cellphone the quest power-wise

[spark latch]

Hi there! I'm wondering if anybody can help me out in here, I have a world and it runs pretty well but for some reason, the world has a massive lag spike to everyone when another player joins the world. Does anyone know how I could fix this?

[versed lichen]

Any player with any avatar ?

[spark latch]

yeah

it usually starts to happen once 5-8 or more players are in the world

[hybrid ridge]

Do you have any scripts that deal with player login?

or is it mostly a scriptless world?

if so it may just be VRC in general

[spark latch]

I have scripts for mirrors, object toggle for post processing and world objects, video player, the VRC Billiards, Skee ball, and VRCadet pinball machine, and a few objects that are pickup objects. My concern is that there is two car models in the world that may be affecting optimization.

Good thinking though, I should look at the scripts it's likely that may be the issue

It appears to happen mostly with heavy avatars

[untold apex]

those heavy avatars might have a lot of colliders built-in.

excessive collision checks is a great way to lag a world.

[spark latch]

True

[nimble osprey]

whats a decent texture resolution to make it look nice but not laggy/big download?

[untold apex]

totally arbitrary. depends on how close you're getting, what the texture is, are you atlasing or tiling textures, etc

the best resolution to use is the minimum required to make your object not look terrible

[pallid gale]

like Texel density might be a useful concept to learn https://www.youtube.com/watch?v=2-mIY87314g

[vale dock]

need some help understanding the profiler / debugger

i have this scene that has a large number of meshes/game objects but all of them are static and should be batched down into like 11 batches since thats the number of materials these objects share

where exactly is the total number of drawcalls being described? on the one hand it says that the total number of drawcalls being used is 163 which just shouldnt be true if there is only 11 materials being used and theyre all being batched, and on the other hand the frame debugger is implying that there should only be 30? unless im misunderstanding something

[vale dock]

im just going to assume that the number of passes/drawcalls in the frame debugger is the final number of drawcalls in this scene after all batching is said and done and hopefully i dont get bit for that

especially considering that i can just walk into my own world in VR totally fine

no idea how it will hold up full of people though. yet

[obtuse bear]

This is all very inaccurate data, a number of optimizations are performed during the build and the number of calls is always reduced.
But the number of draw calls causes almost everything that renders. Shaders, lighting, UI canvases, poly count, materials and textures.

[twilit atlas]

you can btw step through it and see how it renders in the game window

[viscid hatch]

sexy

[glass dust]

Hmm, is it possible to render something for only one eye and duplicate it on the other? I have a procedural skybox shader which is working pretty well, but the performance isn't quite where I want it. Since it is a skybox, the eye parallax doesn't contribute to anything since it's infinitely far away, so in theory I could just get away with rendering it once and blitting it to the other eye. Has anyone implemented this, and how?

[pallid gale]

you could just turn the procedural Skybox into textures

[glass dust]

Unfortunately not, it includes my (animated) cloud shader

[stable pecan]

Running into some issues with my world performance when facing my mirror, its a smaller room in general. Any optimization tips?

[copper valve]

I'm having a weird issue on Quest where after a while of being in my world the FPS will increase. I want to figure out why it starts out 10fps lower for a good few minutes.

[tulip berry]

is it better to have one particle system with all the particles or many particle systems with less particles? basically making fireflies over a large area, a couple particle systems with 10 max particles or one system with 100?

[quasi flower]

From my experience just use the one system but if you need more then one it’s not a big deal. It’s more what the system is actually doing. 100 particles isn’t gonna do hardly anything to frames so don’t stress about it

[shut thunder]

So how do I so occlusion with udon?

The only tutorials I could find for still going off the Sdk 2 set up with triggers

[fallow drum]

Occlusion is a unity thing, it is unaffected by udon

[shut thunder]

https://www.youtube.com/watch?v=KF0_5eYry2M I meant something like this love❤️ not to sure how to do something tigger based in new udon system haha

[fallow drum]

Oh, you'd just put trigger colliders with an udon behavior player enter /exit events to unload stuff.

Sounds like a lot of work though when you could just set up the builtin unity occlusion and it works fine (Most of the time XD ).

[shut thunder]

Ok got ya hah sounds good. Lol it’s been along time since I’ve worked with the unity and working with unity plus the Udon thing is so confusing 😵 thank u for the help

[fallow drum]

No worries.

[pale pine]

Anyone got experience with Occlusion culling?

Have an issue where my assets glitch in and out constantly.

Just not sure if I can fix that using Smallest Occluder/ Hole

Seems to only glitch when you get kinda close to other assets.

[hearty ore]

There are some tutorials out there, but a common pitfall of occlusion culling is its not perfect or (mostly) guarantees objects are visible like frustum

[pallid gale]

[cinder tusk]

Does anyone have any tips when it comes to finding the causes of various crashes for a game world for lower end players? I've not been able to replicate myself but last night we were having various peeps suddenly crash out and I'm not sure if its my world, VRC, just them, etc etc. But we did have some times where suddenly like, five people would crash out suddenly all together while everyone else was fine.

[untold apex]

I'd guess that's more a server problem than something specific in your world. it's probably worth another stress test with lots of players just to be sure.

[rose wolf]

try asking for debug logs when that happens. thatll hopefully get you more info on the situation

[cinder tusk]

Hopefully going to do more testing this week. I've worked out some ways to reduce about 300 draw calls so far that should help people as well.

[pallid gale]

out of curiosity what did you do to reduce all of those draw calls

[cinder tusk]

Turning off the real time directional sun light when the local player is entirely indoors and doesn't have a view outside for a start.
Also turned off GPU instancing on some shaders, only used on very small meshes and also significantly reduced the number of light probes. The default settings for magic light probes put a ton in and really I only needed. One every 2m or so.

[long pumice]

i need help my world is pc only and not quest compat how do i make it quest compat

[untold apex]

switch the target build to quest via the control panel, then pray that your world will actually perform well

[hearty ore]

How expensive are custom render textures with a pretty low refresh rate (as in not updating often)

[torn crypt]

I imagine the bigger perf hit will be from the camera rendering (assuming you're manually updating with camera.Render();?). I think it's a bit of a loaded question though. There's some memory overhead with render textures but that'll ultimately depend on the size and format of the RT (+ if you're using AA, need mips, or need it to have a depth buffer).

It'd also really depend on the use case too! For example, if you need to do something with ReadPixels to copy the render texture -> Texture2D - you can definitely run into perf issues / stalls but that's not native to the render texture itself obviously

[deep flower]

if you're talking about shader-based custom render textures, the performance impact should be the same as a regular texture during the frames it does not update. performance impact during frames it updates depends on the shader used to update it[and the size of the texture], but in my experience it's not too bad if you don't go overboard with scale.

since unlike camera based render textures, the scene does not have to be rendered again, so a whole lot of time is saved

which is why, if you can achieve the effect with a shader based custom render texture, it's better to do so than to do it with a camera-based render texture setup

[outer quartz]

What is the best way to profile a world for performance? Is the built in unity profiler the way to go or is there some 3rd party system.

[torn crypt]

Profiler and Frame Debugger are definitely the first ones to use + should give you enough insight to be alright!

If you have mystery perf issues that can't be tracked down by either of those, then you can break out the big guns with RenderDoc or Intel GPA in client too (but I feel like that's rare)

[outer quartz]

Thank you! Going to start learning how to use and understand the profiler.

[lost storm]

Hia I need some help anyone know how to do x-ray shaders for the quest for like game markers

[solemn tapir]

An X-ray shader, which I mean honestly you'd want to elaborate. But as I understand what you're asking. Would require a grabpass, which can't be done on quest in worlds or on avatars.

[spring blade]

Howdy :3 does anyone have any rough guideline or estimate for texture sizes? I've made many of scenes before, but never for VRChat, and so I fear I might go overboard with high res textures that aren't necessary for VR and will make it so the worldsize is larger

[twilit atlas]

crunching textures can remedy the size to degrees, also look into VRWorldToolkit, it helps you to mass import textures and have an overview of uncompressed sizes

[spring blade]

thanks a lot cake! ^^
I'll definitely look into that toolkit

[lost storm]

Like x-ray so they can see markers like in Mudder and among us

[wind portal]

hi, i want to make a quest version of my world, the docs seem to be a little outdated and there isnt much information about world limitations. Ive heard people say that video players are not supported but dont see anything mentioned about it on the docs.
Do i need to remove any video players?
Also the docs mention a 50mb world size limit but didnt a recent vrchat update list in the patch notes that its now a 100mb?
And are there any other things i need to take into consideration? Thanks for the help!

[unkempt summit]

world size limit is 100mb. Custom shaders are allowed but those that use grabpass does not work (recommended you download vr worldtoolkit as it can warn you on that). Transparencies are fine but it is heavy so don't use it too much. Video is supported but NOT youtube links, videos work fine if you host them privately like google drive or dropbox.

[wind portal]

so if i am using merlinvr udon video player, it would be best to just disable that object or completely delete out of my hierarchy?

[unkempt summit]

Most udon stuff should work fine as it is, unless you are using shader trickery. So in many cases, converting the world to Quest should be pretty straightforward without needing to change anything much. However optimizing the world for Quest is another matter. Real time lights, unoptimized things, undisabled mirrors will slow down on Quest devices greatly. It is best to look at the Stats in Unity and try to achieve a drawcall 100 and below (the lower the better)

[unkempt summit]

If you are maintaining a PC/Quest world together, basically how networking works is the scene hierarchy must be exactly the same. So if you delete the video player from Quest, it must be deleted from PC as well if you want to maintain sync. However, you can disable the video player component only on Quest and sync will still be maintained as the hierarchy is not changed. (Of course this means Quest users can't watch videos)

However since video player works on Quest (just not youtube), you can leave it in as it is actually. It will not cause any problem except Quest people just cant see youtube links

[wind portal]

i see, good to know

[unkempt summit]

PC users can also insert non-youtube links to allow Quest users to watch videos

[wind portal]

and yeah, i am trying to maintain a pc/quest world. im looking into making spaceship hangout quest compatible. the world has been out on pc for a long time already but i recently finished a big update. So now im looking into the possibility of making it for quest. i just dont have a quest myself so i have to rely on friends to test it for me

[unkempt summit]

yeah, in this case the important thing is to look at the drawcalls. Quest is surprisingly weak and I did not know how terrible my world performed until I had gotten a Quest myself. (It was running like 30fps which Quest users told me it is fine but I'm like, no that's not)

if you can keep it to like below 30 it will be great, otherwise aim for like below 100. Anything above is not really good. Avoid realtime lights, transparencies, mirrors, and make things static.

[wind portal]

whole world is already static, and lights are baked. World itself is pretty big though.

duplicated project is currently still switching over to android, taking a while, ill check the draw calls in a bit, but im pretty sure it was more than a 100 when i checked that a couple months ago for the pc version

[unkempt summit]

you should enable local cache server to reduce the time it takes to switch over, it helps a lot https://docs.unity3d.com/Manual/CacheServer.html

it takes up space though

[wind portal]

so i know you can look at the stats menu ingame to see your draw calls, but is there a way to see what is adding to that number?

[unkempt summit]

What I do is I look at the stats within Unity itself after pressing the play button. I can then identify the biggest culprits by disabling/enabling gameobjects

oh yeah remember that enabling global instance on your materials helps reduce the drawcalls

[wind portal]

is it not enabled by default? if so are there any downsides to it or should i just enable it on both quest and pc version?

[unkempt summit]

there are no downsides i think, just enable it on all of them as you can

[wind portal]

alright good to know

[unkempt summit]

it is not enabled by default

[wind portal]

i wonder why thats the case then

@unkempt summit so this is if im looking away from my world (in the pc version)

and this is if im looking towards the center of it

[unkempt summit]

ah, yeah that's definitely not good (even the FPS itself is not good if this is on your PC)

set up occlusion culling by defining an occlusion area and then bake occlusion

[wind portal]

ingame performance sits around 74 fps on my index, which is basically as high as ive ever seen in vrchat if its not a blank world

[wind portal]

already have that

[unkempt summit]

ah hmm

[wind portal]

from everyone who has been in my world so far, theyve all said performance is great ingame

[unkempt summit]

then take sometime time and disable certain parts of your environment to get a gauge of how expensive it is, and see if you can do anything about it. Those drawcalls can definitely be improved

[wind portal]

alright

ive also seen mentioning of merging meshes, but does that help if youre already occlusion culling?

[unkempt summit]

yeah what I mean is that FPS does not mean a good sign if you are hoping to port it to Quest, which is much weaker. For example my world when optimized is like 500 fps and above

[wind portal]

ah i see

[unkempt summit]

I personally don't go to that extent haha (but I use only low poly assets so I don't know)

see if you can identify the expensive things in your world, there is a good chance you can reduce it. But if you cant then what the heck just upload it

[wind portal]

i have my world laid out like this, when i disable individual sections, most dont change anything, only the ones that are in front of me reduce it by about 50-100

[unkempt summit]

oh yeah you should see if disabling the mirror helps. If only the mirror is causing that issue then it's a simple problem to fix

[wind portal]

mirrors are off by default

[unkempt summit]

ah okay. Hmm what's the drawcall if you disable everything except the room you are in

[wind portal]

depending on where im standing in the room, 50-70

i just enabled gpu instancing on all the modular world pieces materials

[unkempt summit]

so its only the rooms that you dont see that is adding all those drawcalls?

[wind portal]

seems like it

i dont see them because im behind a closed door, but the door isnt static for occlusion culling

[unkempt summit]

ah. Well if there's no choice then it's fine. Personally I did a bit of work by segmenting my rooms and then having a toggle such that, if the player is in that area, the room is enabled

but that is a bit of manual work haha so by default, this is probably the best you can do without doing things like atlasing all your textures

[wind portal]

this is with gpu instancing on, didnt seem to affect much depending on where im looking

[unkempt summit]

yeah that scene looks nice, maybe that's the limit you can go as far as the automatic optimizations goes

[wind portal]

alright, well, thanks for your input, really appreciated 🙂

[unkempt summit]

no problem, glad I could help!

if I want to try optimize that, I'll put area based toggles to manually do my own culling

just to enable/disable the rooms that you have in your scene, it seems well organised

[wind portal]

well, the issue with that is, from where i was standing. the areas i could disable that affected draw calls, if i disable them, they would disable wall pieces visable at that point

[wind portal]

for example, the theather room had draw calls reduced if i disabled it from where i was standing in this picture, but the walls you can see through the door frame would have been disabled by doing that

[unkempt summit]

ah

maybe you can rearrange the scene haha

put the walls into another object

[wind portal]

so it looks like the occlusion is already doing a lot of the work

[unkempt summit]

ah yeah

[wind portal]

i do actually have them seperated like that

[unkempt summit]

I see

[wind portal]

let me see if disabling anything else than the walls helps draw calls

looks like i could get around 30 draw calls per room repending on what parts i disable

but it still varies hard depending on what part youre looking at

[unkempt summit]

Yeah I found out that manually disabling rooms is better than the occlusion culling

I guess the issue is you have a lot of materials and they are not atlased

Which is a lot of work to fix

[wind portal]

one more quick question, can i have settings be different on objects without causing syncing issues?

like i have a script that spawns new space locations, and some locations have RT lights, theres a button to disable those, but by default its on. can i change the script to have the default be off, or do the settings need to be the same? @unkempt summit

[unkempt summit]

Try not to change the scene hierarchy by not instantiating new oblects

Just disabling and enabling is fine

[wind portal]

its not instantiating them, just toggling already existing objects

alright thanks

[deep flower]

that's what occlusion portals are for.
they basically act like a solid object for occlusion culling, except it has a toggle to "open" it, making it no longer occlude stuff.

[molten bison]

Yes I am using occlusion portals too and they work nicely. Interestingly enough I also use that same asset pack :) It's great value but some walls have transparent materials I think which disables occlusion culling for them, so I blocked stuff manually with EditorOnly cubes.

But I still think manually toggling rooms might be better in a similar way for doors. Turning off Udon processing and audio sources for examples in blocked rooms should also give some more performance.
Just have to make sure scripts can resync after being toggled back on I think.

[outer quartz]

Use the Draw call/batches number from the statistics window but take the "FPS" a little less seriously since unity is including the time used to run the editor in that number.

I just wanted to make the comment for others that might think the FPS would be close to in game FPS

[unkempt summit]

ah yeah it's not

[outer quartz]

~~ Also, and someone please correct me if they have more info, organizing a scene with empty game objects has a run time performance hit because they are still technically game objects. ~~

As in I remember seeing that the game engine is doing parent child transform math for all of them.

[unkempt summit]

I would think if the objects' ain't moving it should be fine. (Otherwise that seems to be a big hindsight)

Esp if those are already static

[outer quartz]

Did a little more looking and seems like its for moving objects like you said.

I still wish unity had a folder system for the scene heirarchy

[pallid gale]

https://gitlab.com/s-ilent/SCSS/-/wikis/Other/Occlusion-Culling @wind portal a helpful guide on occlusion culling and you'd probably want to see if you can put your non tiling textures on a atlas

[young dove]

Hi there, is it normal for draw calls to batch in spikes like so?

https://cdn.discordapp.com/attachments/307446969029230593/958920062713098290/unknown.png

I had just thought I would expect batching to be persistent, or do I have the wrong idea of how it functions?

[young dove]

determined it to be the behavior around a realtime reflection probe

[hearty ore]

Does SendCustomEventDelayedSeconds use a form of Update on the backend for when to trigger timers?
I'm asking because I'm curious as to if looping with a delay seconds is better performing than just using Update or FixedUpdate

[autumn quest]

how do i help Compress my world for the Questies

i Compressed a few Textures and Audio files

but

[pallid gale]

https://github.com/oneVR/VRWorldToolkit this is a handy tool that has a compress all textures button and tells you what takes up file size on a map

[autumn quest]

how do i use it to compress stuff?

too lazy to read the 2 hours of exposition

@pallid gale

[pallid gale]

the page for it is not terribly long

[autumn quest]

mm

still

like if you're going to do World development you're going to have to get used to reading documentation

[autumn quest]

ive been making worlds for over a year, just never needed to go higher than 100 MB yet, now i have, and need to fix it

[pallid gale]

then yeah the screenshots I posted would cover what you need to know to Crunch compress everything

[pallid gale]

do you have the Android build installed for Unity

[autumn quest]

ah

no

ill fix it

[topaz hinge]

asks for help
gets docu
"mmmm nah too long, spoonfeed me the docu"

[fallow drum]

When it takes longer to type out the question than it would to just read the page provided with the info 🤣

[serene sparrow]

Hey mates, i'd like to ask if anyone has a link on the low hanging fruit for quest map optimizations?

i have a very simple world with a large plane as a floor, a mirror, wolfe's video player, a billiards table and a few avatar pedestals. It seems like the quest is kinda struggling to run this, especially when the balls are rolling in the billiards table

is there anything i should look at before straight up disabling some bits of the map?

I'll be taking a look at the import settings guide from the pins, and maybe try to switch around some materials

[solemn tapir]

The pool table will always kill quest. It should be on a toggle and defaulted off locally for them. Also do all you can to reduce the draw calls by reducing the number of materials. Can even remove the drop shadow on the balls. There's not much you can do to improve this. The physics of the table is simply too much for a quest.

Putting the table in its own area such that the rest of the world can be disabled using an area trigger can help a bit too, so that the only thing really running is the table.

[rose wolf]

didnt someone here figure out why the table was too heavy and how to fix?

[serene sparrow]

hmm i see

[solemn tapir]

There's been a few forks that have in various ways improved it. But afaik the community table hasn't implemented any of that.

[serene sparrow]

it was meant to be my home map, with these couple of things kinda always on

[solemn tapir]

It's just simply hard to manage the physics for the quest. Especially q1 . Q2 does a lot bettet

[serene sparrow]

wasnt aware it was such a performance hog

[solemn tapir]

I mean having everything on by default is kinda bad design anyways. Just using area triggers to manage where the player is, ensuring that only logic in that area is running, is a very basic step to easily improve performance

[serene sparrow]

i mean, it is literally a 5x5m or so square

😆

but yeah, i'll see if i can fiddle with the table

[solemn tapir]

Well, might be a good idea to start building out some areas xP

[serene sparrow]

its just a spot for me to spend 5 seconds calibrating in

and maybe play a game if someone joins in on me

you mentioned the shadows being remove-able?

i'll try to gut that table a little

[rose wolf]

i mean, if the planes on y=0, you could use the original pool table. that ran well

[serene sparrow]

original?

[solemn tapir]

You'll break sync if you just remove them. You can just remove the shadow, just remove the mesh renderer. And plz don't use the OG table. He deserves no support for his bs

[serene sparrow]

i dont mind gutting both PC and quest equally, would that break sync as well?

[solemn tapir]

Also, your pens each use two shaders. You can reduce a ton of draw calls by replacing the material on each pen to be the same.

[serene sparrow]

would that make all pens share the same color?

[solemn tapir]

No

I mean the body of the pens

[serene sparrow]

Ah i see

[solemn tapir]

Each is two materials

[serene sparrow]

do you know if there is anything i need to watch out for in the video player?

i might just disable it on the quest lol, seems fairly useless

[solemn tapir]

Not really. It's just a player. ProTv is prob the best cross platform player but all the major ones work fine

[serene sparrow]

protv? ty

[solemn tapir]

It's free on booth

[serene sparrow]

i just got the first one that showed up on google

[solemn tapir]

As long as they're identical you won't break sync. It's often just easier to disable the mesh renderer than to worry about that but none the less.

[serene sparrow]

oh, i can disable the mesh without breaking it, great

pretty new to this, thank you

[solemn tapir]

Sync is determined by object position in the hierarchy, not the contents of the objects (simplification)

[serene sparrow]

so it is part of the scene even if i upload it as disabled?

[solemn tapir]

Unity assigns a sync ID from the top down. So sync objects tend to be best places at the top

Yes.

[serene sparrow]

i thought it cleared up stuff, but that might've been avatar uploads

[willow panther]

Hey, So i have a world that was made for quest using a bunch of models that included LOD To minimize lag, Is there a way i could bypass the sdk default settings and change the LOD Bias?

[serene sparrow]

i managed to get the world running way better by re-assigning materials, thank you

but i broke the table 😂

oops

[pallid gale]

you're not able to tamper with the LOD bias settings of the sdk

[hasty acorn]

When i build and test my world it sends me home, any help?

[solemn tapir]

Quest or PC?

Do you have a spawn point set in your world descriptor or is it empty?

[hasty acorn]

Got it fixed, thanks

[pallid thicket]

@plush comet I need to report a vrc user

They're a zoophile

[topaz hinge]

dont tag staff, read #moderation-reports and follow its instructions

[pallid thicket]

Ok

[serene sparrow]

wtf lol

[lilac saddle]

I do optimization this way but when I use the mass compression it never seems to work

Rn I'm making a club world can anyone tell me any tricks and methods they know for performance boosting?

All I've done for optimizing is just dropping Size of materials to 1024 and compressing it at 50% quality

[untold apex]

material atlasing, careful use of transparency, gpu instancing, static batching

[lilac saddle]

Helps with Mb size at least

I don't know other methods

[untold apex]

dropping texture sizes will reduce build size but not necessarily have an impact on framerate

[lilac saddle]

I'd love to learn all methods if there is videos or guides for fps boost and dropping MB size

[untold apex]

material atlasing basically means combining the materials of neighboring objects whenever possible so that for any given viewpoint you are using as few materials as possible

[lilac saddle]

Ahh alright I'm not sure how to do that though

[lilac saddle]

I'd love to learn about all this stuff

[untold apex]

you can probably just look up atlasing. it's the reason the standard shader exists... 90% of materials can be described by that one shader. let's say you have a bunch of dishes and utensils sitting on a table. you could give each fork, knife and plate its own material, but that makes the render engine work way harder. instead, you set up the UVs of all those objects so that they fit within a single map, and use textures to differentiate the various material properties. now all that table setting is a single material

gpu instancing is what you use for objects that exist over and over again in the scene. you just enable it in the shader. the engine will automatically try to optimize identical meshes using the same material if this is enabled

static batching is a semi automated process. anything in your world that doesn't move, generally speaking, should be static. unity will automatically combine nearby static objects into single meshes where possible to save on draw calls

this requires that you use baked lighting, which is generally what you want for performance anyways. real-time lights area huge performance hit and should be avoided. always bake your lighting

you also have occlusion culling, which takes some work to set up. this acts as a hint to the engine to tell unity that you can't see through certain objects, so it can hide things behind that object to save draw calls

[lilac saddle]

Alright I'll definitely look that up that sounds very useful

[lilac saddle]

Ooo that's very useful

I never knew what those meant

[pallid gale]

https://static.planetminecraft.com/files/resource_media/screenshot/1217/terrain_2068984.jpg

like here's an example of a texture Atlas

https://gitlab.com/s-ilent/SCSS/-/wikis/Other/Occlusion-Culling

[lilac saddle]

Ohhh that makes sense

[pallid gale]

documentation on occlusion culling and something that also helps is making sure all your lighting is baked so that you're not needing to do calculations every frame on how your shadows work

[lilac saddle]

90% of my lighting is baked but I have some real time lights

That need to stay that way

[untold apex]

yeah, then just be extra careful to minimize other expensive operations in those areas, and understand that they're going to impact performance quite a lot

[lilac saddle]

This is without a doubt most expensive area

[hazy haven]

If one of your shaders rely on the realtime directional light, you can delete the rest of them

Only if you have duplicated it around the world

Also whatever that fog is on the floor, if thats a particle system then you should reduce it down until you start seeing changes.

[lilac saddle]

It's a smoke machine from a prefab pack I have

[lilac saddle]

is there an easy way to see if occlusion culling is working

[lilac saddle]

also which is better gpu instancing or static batching

[untold apex]

if you're using copies of the same mesh with the same material over and over again, gpu instancing is probably the better choice. but it's hard to say if one method is always better than the other. profiling is the way to tell

if your objects are very lightweight, like just a handful of triangles, you're probably better off static batching

[solemn tapir]

Scene view, top left, change the render mode from shaded to overdraw.

Then go to the occlusion culling tab, click on the visualization tab.

On the camera in your scene view, enable view lines and volumes.

Move camera around.

[lilac saddle]

so the way in interpreting this is, high quality prefabs = gpu instancing (if im using multiple of the same kind) and static batching for stuff like walls and floors and low quality stuff

[lilac saddle]

alright thanks

[lilac saddle]

should my camera be made big enough to cover entire world or small

[untold apex]

yeah, assuming that those high quality prefabs are being used repeatedly throughout the scene and with the same material, and have more than about 256 vertices

[lilac saddle]

alright

im still trying to figure anti aliasing rn

[untold apex]

if you have a lot of one-off props there's no real reason to gpu instance. as far as anti-aliasing goes there's not much you can do. any post-processing method for AA is not compatible with VR

[lilac saddle]

so i shouldnt bother with antialiasing?

[untold apex]

i assume you're applying it to a post-process volume? it won't work in VR.

[lilac saddle]

never done it before

[untold apex]

or, well, it might do something, but definitely not something you want it to do

[lilac saddle]

i dont think pc users are gonna lag in my world anyways

im mainly trying to get things optimized so there is minimal lag when my club reaches higher player count

also any tips for reducing mb size?

[solemn tapir]

Without reading everything typed, post processing should only be used for Bloom and color grading. That's it.

[solemn tapir]

Use crunch compression on all textures and compress all FBXs to medium

[untold apex]

crunch your textures and use as low a resolution as you can get away with based on your level's needs

[lilac saddle]

oo never knew about fbx thing

i usually crunch my textures to 1024

[untold apex]

mesh compression is available in the inspector for any input mesh

crunching is not the same as file resolution

[lilac saddle]

my light maps are a big killer rn for mb size

[solemn tapir]

Yes. Click on the fbx, in the inspector, set to Medium. You'll typically never see a loss in quality at medium. Don't go higher than that or it will reduce the visual quality.

[lilac saddle]

lightmaps massive killer

[solemn tapir]

Yes. Baked lighting takes up space. Tailor your settings to be as low as possible while maintaining the visuals you desire. You can also crunch your light maps

[lilac saddle]

about 48 different light maps

at 1.3mb each

thats accounting for 62mb

[solemn tapir]

Your meshes are all separated

[lilac saddle]

fuckign hell

is that why i have soo many lightmaps?

[solemn tapir]

Most likely.

[lilac saddle]

how can i combine them reduce light maps?

[solemn tapir]

Using a script to do so in unity or export and do so in blender (best method is blender use fbx exporter to send to blender). You want to be logical about it tho. Things should be joined in neighboring groups, not all together, so frustum culling still works well.

Also, many things may or may not even need light mapping. Ensure you're light mapping only the meshes you need. You can use shaders to create the look of shading without actually baking lights to it.

There's never a one size fits all solution. Stuff like good optimization is a lot of things all coming together in a logical way for your project.

[lilac saddle]

seems like i have a lot to learn

[lilac saddle]

how can i stop unity from creating light maps for meshes?

by unchecking the create lightmap uvs box?

[untold apex]

turn off "lightmap static" in the inspector

[lilac saddle]

where can i find that?

[untold apex]

on the top right corner of the inspector for any game object, you have that "Static" flag. but there's a bunch of options within that

you can pick and choose what type of static flags you want for any given gameobject

[lilac saddle]

this?

[untold apex]

ah sorry misworded, just turn off contribute gi

[lilac saddle]

so turning that off will mean it will not get light mapped?

[untold apex]

yes

it won't be considered for lightmapping at all

[lilac saddle]

alright good

ill do that on a lot of things that wont even need light

and see how it turns out

[solemn tapir]

On the mesh renderer itself. Under the lighting tab....

But yes. You should also uncheck the tag. Regardless. Section B of the mesh renderer, disable everything you don't need for that specific mesh.

[lilac saddle]

alright

[lilac saddle]

for this where is the option to set it lower/higher?

ohh nnvm

spotted it

[untold apex]

Mesh Compression

[lilac saddle]

so weird i reduced the amount of lightmap there and somehow my build size is the same

[untold apex]

reducing the number of objects present in the lightmap is likely to just make the other objects take up more space in the uv map. what you might need to do is adjust your lightmap resolution so that you're using less texels per unit

[solemn tapir]

U also need to ya know. Rebake

[fallow drum]

They shouldnt all be seperate lightmaps though. You need to turn up the lightmap resolution in unity id assume

looks like you're baking a whole lot of 1k lightmaps instead of 4k ones

[fallow drum]

what is this set to?

[lilac saddle]

Alright

[lilac saddle]

I did rebake.

[lilac saddle]

I'll look into this tomorrow. I'm working rn (night shift) but thank you

[fallow drum]

👍 feel free to @ when you do

[cerulean locust]

can someone tell me what does this mean and how i can fix it?

[fallow drum]

Expand your error console and see if there are any other errorcs coming before that.

[frail wyvern]

how do you view how big a filesize of a quest world in unity?

[rose wolf]

either with the worldtoolkit by 1 or you can manually check with the compilelog

[lilac saddle]

@fallow drum

ok so

it was set on 1024

so i changed it to 2048

rebaked

took a lot longer

i have less light maps but my build size is bigger

[versed lichen]

How big is the world you're baking ?

[lilac saddle]

pretty big

its a club world

[versed lichen]

What lightmapping settings do you have ?

[lilac saddle]

untouched

ill send ss

[versed lichen]

You need to scroll down

[versed lichen]

bring the texels down by half

and bounces to 5

[versed lichen]

enable ambient occlusion

[lilac saddle]

max for bounces is 4

[versed lichen]

Ah, go with 4 then

[lilac saddle]

which texels

this

or

[pallid gale]

texels per unit should be at 20

[lilac saddle]

alright

so 20

anything else

[pallid gale]

Ruuubick instruction should cover most everything else

[lilac saddle]

alright

[blissful wasp]

Hey, my pickup items have different topology/tris and such
Would it still be a good idea to atlas them to the same material and use GPU Instancing?
all my item textures are around 16x16 so an atlas wouldn't lose any detail

For extra context I have around 6 unique items (more planned)
and 2 pairs which are the same mesh just different texture/material those I assume would be good to atlas
(then I'd be able to make more duplicates too) what I'm wondering is if the unique ones would benefit
because from what I understand even if it's the same material if it's a different mesh then it's an extra draw call
so I dunno if it'd help much there
and then as far as saving dl/cache size as I said my textures are like max 16x16 so I doubt there'd be much

[agile hawk]

It's good to atlas. Even if it's not to reduce draw calls.

Though, from the context I have is that you have no identical mesh with the same material, so, GPU instancing wouldn't help reduce draw calls or do anything.

GPU instancing requires identical mesh, identical materials, and static batching off.

Static batching works a bit better because it only needs identical materials, but, don't work on dynamic objects.

[inland bobcat]

What could i do to try to lower my world size

its like 200mbs 😭

234

[unkempt summit]

Download VR World Toolkit, make a build and then you can use it to see what assets are taking up space, so you can think how to reduce it

[inland bobcat]

Pretty sure its mainly lightmaps but ill look at it

[unkempt summit]

if its lightmaps then you'll need to reduce the quality. Other factors could be you are using huge normal maps or textures (well just scale them down using gimp or photoshop)

but first to understand why, its best you get VR World Toolkit

[inland bobcat]

importing it right now 🙂

[twilit atlas]

don't scale them down using photo manipulation software

use VRWorldToolkit to set the import sizes accordingly, it has a mass importer tool for this

[unkempt summit]

yeah, you'll need to make a build first before it will show the information. It shows information from your last build

[twilit atlas]

also allows you to set crunch levels

[unkempt summit]

oooh

[twilit atlas]

providing high resolution base graphics/textures and then setting the import settings is a way more flexible workflow

[solemn tapir]

Just remember that crunching textures only lowers the download size, not the size in memory...

[near juniper]

What does texture streaming do exactly?

Is it supported in VRC?

[pallid gale]

https://docs.unity3d.com/2019.1/Documentation/Manual/TextureStreaming.html

[near juniper]

Is it literally just a memory cap?

So performance gets priority?

[solemn tapir]

Yeah. Helps with mipmaps.

If you're not using mipmaps, well

[near juniper]

awhh poopie

[solemn tapir]

Well yes. Cuz the entire terrain is one mesh. And you're always right next to it

Could do it still if it's just some generic meshes with textures that aren't specifically terrain and your terrain is cut up in chunks.

[pallid gale]

I guess the question is would that actually help much in vrchat given that you're not going to be loading like big open-world Maps?

[cursive rock]

Who knows how to make the on/off button control?

[cursive rock]

How did you solve the problem?

[obtuse bear]

Leave one variable game object, and add a mirror there in the inspector.

[solemn tapir]

#world-development message

You named your variable "vrcmirror" but that's just a variable to toggle a game object you just arbitrarily names vrcmirror. If the public variable is left empty, it defaults to "self" so it toggles the object the Udon behavior is on. I explain this more at the link above. The gist is you need to drag and drop the actual mirror into the public variable.

[cursive rock]

How do I sit a chair? 👉 👈

[unique kite]

You don't until you fix the errors preventing the udon behaviors from loading. You also need to use the appropriate channel which would at least demonstrate you are paying attention. #world-development

[cursive rock]

ok

[spiral nova]

Have you ever used this plugin, I imported it into minecraft but I can't use it

🙁

[versed lichen]

What do you mean by imported into minecraft ?

[spiral nova]

world

Sorry, my English is not very good

imported it into my world but I can't use it

😱

[spiral nova]

It seems like it's a problem with my setup

[versed lichen]

Were there any console errors in unity ?

There might be a specific udon version required

[versed lichen]

These aren't errors

[spiral nova]

It doesn't seem to be this either

[versed lichen]

Is there only one ?

[spiral nova]

yes

I don't know why

Which one should I use

[versed lichen]

I'm not sure, is there no documentation on the item page on booth ?

[spiral nova]

The second one has the suffix of unlit

[stray oak]

Do you have UdonSharp in your project? Maybe it requires that

[spiral nova]

I imported UdinSharp

🙁

[stray oak]

Did you import UdonSharp first, before importing the plugin?

[spiral nova]

yes

[spring laurel]

Does anyone knows if scaling a gameobject impact the world's optimisation ?

I mean does a very tiny prop with a lot of poly have an higher impact than an enormous low poly structure ?

I'm trying to do an Island so I wanna know this to think about how big I can make it

[unkempt summit]

you can have a high poly prop with LOD levels so you dont have to render the full model from far distance, but if you dont do LOD then that high poly prop will be heavy

whereas low poly structure, obviously its good

there's no way the low poly prop will be heavier than the high poly prop at any size, unless you do LOD for the high poly prop

[spring laurel]

Okay thanks

So the size of the props doesn't really change much about the impact ?

[unkempt summit]

even if you are drawing a high poly prop with a size of 1mm, all of the polygon's drawing will have to be computed, they dont get culled automatically

so yeah, using LOD is a way to reduce the impact of high poly stuff

[spring laurel]

All right

So basically if I use a cube, I can make it very big and it wont affect anything ?

[unkempt summit]

that is absolutely no problem yeah

[spring laurel]

Let's go thanks

I'm doing an island so I'm gonna make a lowpoly and scale it a lot

[unkempt summit]

anyway, the impact of that is so insignificant compared to drawing 20 avatars on screen, that has no LOD level

other factors, such as changing materials, will affect more than just drawing a larger triangle on screen

yeah, upscaling a low poly island is def no problem

[spring laurel]

I'm planning on doing a cartoon water shader, will the size of the plane (with the shader on it) affect it's impact or it's the same as the island ?

[unkempt summit]

doing as in you are making a water shader or using someone else's

again, any performance hit from drawing a larger triangle is extremely insignificant compared to rendering avatars, so it doesnt matter

so technically yes, but no its miniscule compared to everything your modern device is processing

[spring laurel]

True some avatars are heavier than some worlds xD

[deep flower]

the only thing that scaling up an object might make worse performance-wise is making it more likely for that object to be in frame
if the object is in frame, it impacts performance much more than if it isn't in frame.
although this goes for the performance impact of the shader used to render it, not for the performance impact due to the number of polygons or such.
and unless you do crazy stuff in the shader, that particular impact is irrelevant compared to other performance impacts

[lilac saddle]

Hi! I can't find the settings to lower the resolution of all of the textures in the world. Could somebody show it for me?

[stray oak]

I think that would be in Project Settings > Quality > Rendering > Texture Quality. But I don't think VRChat allows these settings to be modified, so instead you'd need to manually change the import size of each texture

[lilac saddle]

That's not it, there was another setting for is

[stray oak]

Oh, maybe you mean the mass texture importer from the VR World Toolkit? You have to download that separately from the SDK

[untold apex]

there's a package called vrc world toolkit

it has a mass texture importer script that can batch compress textures

[stray oak]

can someone help me with Switching to Android:AndroidPlayer is disabled

[unkempt summit]

you need to download the android SDK for your unity version

check your unity hub

[frigid iron]

1. In Unity hub, click on installs on the left side of Unity hub
2. Click the gear icon on the 2019.4.31f1 install, and click add modules
3. Install the Android build support, Android SDK & NDK Tools, and OpenJDK

[inland bobcat]

yall think me copying and pasting 3 different "grass" items around to make a "3d looking" carpet

would make lag

[untold apex]

hard to say for sure. make sure GPU instancing is enabled on their material and check your draw calls in the game view

[frail radish]

Im pretty sure there is a shader you could use instead, to make it easier, and on top of that

[inland bobcat]

i loaded into the world and it seemed like nothing different was happening, FPS seemed fine to me

[echo siren]

Does baking occlusion really meaningfully affect performance??

[untold apex]

depends on your world and how much objects occlude each other.

[echo siren]

uhhhhh

Not too much I think

[twilit atlas]

occlusion relies on having proper occluders and occludees, it is something you design a world around if you need it

large transparent windows are a very hard design to incorporate into this

your stats look a bit scary for this scene however
are these all real time lights?

[inland bobcat]

The Waffle House!

[echo siren]

All baked except one real time light in the parking lot

im really not sure why it performs so poorly lol

[echo siren]

Yesss! Waffle House On The Moon!

i am on a pretty low end machine, a laptop with a 1060

Is there a meaningful performance hit from having higher res baked lightmaps??

[twilit atlas]

there is also a cost for everything, this has one too but can be ignored

you have a lot of batches and setpass calls

why do you have a realtime light at the parking lot? they end up doubling a lot of the stats

[echo siren]

i think i was mistaken because looking back i didn't see any

how can i affect the batches and setpass calls??

thank you for the help ;;

I keep seeing recs to add occlusion culling, but like we said there's really no case when much of anything is realistically going to be culled

I wonder if it comes down to the fact that this was a DAE model imported into blender to some extent

so

disabling the building mesh makes performance skyrocket lol

that seems to be the culprit

this stupid DAE file has been a nightmare since day one

[solemn tapir]

You can just import it into blender and export as an fbx. DAE alone won't kill perf tho, it's probably super high poly, looks like it's an absurd amount of separate meshes as well so a ton of draw calls, and I assume you've put a mesh collider on each of the meshes. So a ton of bad practices.

Import it into blender. Merge things into logical groups so you have a bare minimum number of separate meshes. Decimate it or remesh it so any high poly mesh is much more reasonable, and export it as an fbx

Basically, way too many draw calls and I suspect way too high poly, especially bad it you're using mesh colliders.

[twilit atlas]

model type is irrelevant, unity imports into its very own representation

[echo siren]

Yeah what I mean by that is that because it was a DAE file auto-generated from CAD, it's not at all optimised for this sort of performance requirement. I honestly might be best suited to just remodel it from scratch because it's not particularly complicated, rather than go to the effort of trying to remesh it. I've spent so much time screwing around with the terrible topology that was generated

[untold apex]

CAD topo is an absolute nightmare to work with. you're best off using it as an armature to model on top of so that you have better control over your edge loops / UV seams, then bake AO/normals from the original hi rez tessellation onto your clean model

[viscid hatch]

I feel like I should be getting more frames less drawcalls, but then you realize it's the lighting

[echo siren]

Yeah D: I learned this the hard way, it's been super annoying the entire time. I thought it would save time given Waffle House model exists but it just made it worse all around lol

Do you have a rec for baking the AO/Normals? Not ever done that before

[untold apex]

it depends on your software, really. i usually use substance painter for this. i'm sure blender has its own system, but i don't know blender.

[surreal shoal]

why arent my atlas'd textures going with the fbx into unity?

[vague umbra]

Is it possible to add items to a VRCObjectPool on start or some other event?

[twilit atlas]

that defeats the purpose of the object pool's synced nature

what are trying to achieve?

[vague umbra]

I have a bunch of items that I am spawning one at a time, and I want to be able to edit one and update them all, so if I use one item and copy it then i'm set, but then I have to update every copy each time I want to make an edit

[vague umbra]

Also, adding 180 items one at a time to the object pool is tedious

[hollow elk]

You can select the game object with the object pool > lock the inspector > select all the objects you want in the pool then drag all of them into the pool at once

[vague umbra]

Where do I drop them to make it take all of them?

[hollow elk]

set the pool back to 0 items and then drag it on the "pool" text

[vague umbra]

omg ty

still a pain to have to delete -> edit -> duplicate though, so some way to programmatically duplicate them and add them to the pool would be great

[viscid hatch]

did you set the atlased texture to the fbx in blender and then export the fbx to unity?

[surreal shoal]

i figured it out. thanks thouh

[lilac saddle]

When trying to compress my world size using the texture crunching option on the vrcworldtoolkit, it will gather the assets for awhile and then unity will crash everytime. Does anyone know how to fix? I am wanting to upload my world for quest use but I am not able to with this issue.

[solemn tapir]

You're probably running out of memory. Manually crunch your textures yourself rather than using the bulk tool.

Also, don't cross post issues in multiple threads. Pick a thread and post once. You end up wasting people's time by doing that.

[lilac saddle]

Will do. Sorry. Also, manually crunch each texture? That would take me forever would it not?

[solemn tapir]

Not really. Depends how many you have, and you can do a few at the same time. You should have your asset folder organized such that they are together anyways. Plus it's a one time and done kinda thing.

[lilac saddle]

I used used project view and search t:texture, it brought up all textures. Then I tried Ctrl+a to select all, but it wouldn't select all and freezes my unity everytime.

How would I do them all at once manually?

[solemn tapir]

You don't want to do them all at once..... That's why you're crashing most likely

[lilac saddle]

Alright, how would I do more than one at a time?

[solemn tapir]

I've personally never used a bulk processing tool. It's not hard to manage your textures. If your project is so absolutely massive and your asset folder is so absolutely not organized then you have other issues on hand lol.

Just go to your textures in your asset folder and drag select a few, or shift click, or control click. Whatever method you want.

Just work through your hierarchy and find all your textures and crunch em. Doesn't take long.

[lilac saddle]

Will try that thanks. Hopefully it'll let me select multiples as I couldn't select but one earlier. I'll try those methods

[lilac saddle]

@solemn tapir thanks, what you said is working. Now, it's been a long time since I've worked on this project. How do I upload it for quest once I'm done compressing?

[untold apex]

switch your build target to quest in the sdk window, then watch for broken materials. anything that uses a grabpass will fail

you need the Android libraries installed if you haven't already; this can be done from the unity hub

[lilac saddle]

Thanks @untold apex

It's been awhile 😎

[lilac saddle]

Anyone know a good way for size reference of objects in the world? It seems like most world have it right where as mine I can't seem to get it porportionate

[versed lichen]

worldtoolkit has a page for that

oh, transform size

Unity cube

[pallid gale]

a Unity cube is 1 meter

and the capsule collider for avatars Collision is 2 m tall for answering like how big doors should be

[solemn tapir]

Or just..... Use a capsule....

3D capsule is 1m x 2m tall

[pallid gale]

oh yeah good point

[lilac saddle]

Alright thanks

It's taking me 5 years to compress my textures sigh

[serene sparrow]

cpu go brrr

[brisk lance]

Should you delete all the lights after baking? Or just leave them?

[twilit atlas]

leave them, you can mark them editor-only if you want, helps when you use bakery components, they will just print warnings in the log

[echo siren]

https://assetstore.unity.com/packages/tools/modeling/mesh-combine-studio-2-101956

Anyone ever tried to use this or similar assets with VRC? Is it possible?

[pallid gale]

haven't tried it but it should work fine as it's doing stuff at editing time generating new mesh files not runtime scripts

[echo siren]

hmmm i wonder if it's worth trying

[solemn tapir]

It works fine, I own it and have used it, including many assets from MC Studio. It's just a mesh combining tool. It is better to do this in blender however. Important to ensure you're fully aware of what it is and if you truly need it or will leverage it.

[pallid gale]

like it's not going to do you any good to combine meshes that are using different materials as an example as that would still be the amount of materials in draw calls

[solemn tapir]

Yes. It's very easy to misuse the tool and actually hurt performance by reducing the effectiveness of occlusion and frustum culling. Everything needs to be leveraged appropriately and with intent.

[echo siren]

Isn't the purpose moreso to automate that process that would have to be done manually in Blender?

[lapis charm]

OK

[solemn tapir]

Wat

[willow gorge]

your worlds are weak

weak i say

[pallid gale]

that's a lot of batches

[solemn tapir]

1.8m tris 3.5m verts. 5k batches. 3k calls.

Lmfao. 101 ways to not design a world

[willow gorge]

its 27'000 square meters of walking space

you would not understand

[solemn tapir]

That doesn't mean it has to be ass designed.

Also floating point errors go brrrr

My world is also rather... Huge and is a literal fraction of those stats. Good game dev is important if you want people to be able to actually enjoy it in VR lol.

Your screen is showing 15ms of frame time with a resolution of basically 720p with a single camera.... I'm sure your post is for funnies but I do hope you intend on actually profiling and optimizing that lmao

[willow gorge]

that train has long left the station

i am working on this autism project since a year and a lot of my mindset has changed since then, i did not follow a structured approach and my choice of tools ||proBuilder|| is a so-called "oof" moment. since it would take a disproportional amount of work in fixing the sins of the past, the council has decided that it is good enough for a night of attentionwhoring before putting it back into storage as a ethernal reminder on how to not do it.

[unkempt summit]

30 fps cinematic game

surprised that much is saved by batching even

[solemn tapir]

It's never too late.... I mean there's no reason to have 3k calls. Like. You're doing something extremely wrong that has nothing to do with probuilder

Like, is ever mesh sperated, and each set as a shadow caster and you're using realtime lighting with shadows?

You can also just export your probuilder meshes to blender.

[unkempt summit]

i wonder how many triangles my large world have, im sure its not close to a million

[solemn tapir]

Tbf gpus can handle a shit fuck ton of polies, as long as they don't have mesh colliders. A static hp mesh won't be too much of an issue. But absurd draw calls def is. Hp meshes really become an issue if you try and do a collision check against every face, ie, mesh collider.

[twilit atlas]

it's why most games build their layout around occlusion culling or let objects pop in via lods if you really need a vast view

[solemn tapir]

Indeed. Designing the world to leverage occlusion and frustum culling is very valuable

[pallid gale]

which is kind of why essentially s-shaped hallways are very common in video games

as it lets you sarv unload one area and loading another without noticing

[unkempt summit]

(but in vrchat people dont care)

throws all the effects without regard for framerate as long as one screenshot looks nice enough to lure people in

[solemn tapir]

super bad ass looking world preview

It's actually just a photo of a texture on a quad and the world is absolutely shit

[twilit atlas]

gamedev is hard, many/most are just doing it as a hobby in vrchat

it's always great if people do decide to optimise

[solemn tapir]

It's my hobby. But it's also important to learn and study and read and watch and ask and implement what you learn and iterate over and over to build something unique and cool that you can be proud of that doesn't nuke everyone's computer

Takes time. And dedication. But if you have those two things, you can manage it. But if you just accept " it is what it is" then you won't get very far.

[pallid gale]

and also there's the extra consideration of low frame rate can make people literally nauseous in vrchat

[willow gorge]

atleast it looks pretty 🥰

[pallid gale]

looks like it would be trivially easy to cut down on the draw calls as it looks like it's a bunch of solid colors so you could put everything on one texture Atlas

[willow gorge]

there are actual colors

and textures

[solemn tapir]

Merge individual buildings.
Atlas textures
Leverage occlusion culling
Bake all lights

[unkempt summit]

did you identify what the costliest parts? You can do that by just disabling parts of your world and seeing the drawcalls go down

that doesnt look like it should be that heavy, culling seems very possible

[solemn tapir]

Culling would def be possible.

But you'd want to merge thing into logical groups to improve culling performance

Is your lighting baked? I suspect you are using realtime shadows too, considering how high your draw calls are

Also, you only have one reflection probe? Is it baked?

A single reflection probe in that scene would only be useful for baking the skybox and nothing else at low res.

[willow gorge]

The Lights are all baked. there are 0 (zero) real time lights.
Billboards are atlassed as best as possible.
Textures are from a asset pack. Which makes it very very tedious to atlas them.
Designing and creating the buildings was done without the practice of separating by materials.
culling is already baked in
reflection probe is baked. Same as the lights with bakery.
i did not put more than one lightprobe because unity literally crashes when i did that.

[unkempt summit]

those stats seems like its because you are viewing from the top, what's the stats if you zoom it down?

[willow gorge]

the 350 megabyte filesize comes from these. and the lightmaps.

[solemn tapir]

Even then, 3k draws is pretty insane

Something is causing absurd calls, it should be tracked down. Consider learning the profiler and frame debugger.

[unkempt summit]

holy moly

disable your gameobjects and see which one is the culprit

[solemn tapir]

Wait. That's street level facing a building. Yet it still has that many draw calls and Tris. Certainly test your occlusion culling and ensure it's working as intended. You can enable a view called overdraw in the scene view to see what is rendering through a mesh in the frustum

[willow gorge]

yes, i have just noticed that i cleared the occlusion data yesterday and forgot to rebake it

[pallid gale]

that would explain it

[solemn tapir]

Occlusion culling has a performance overhead cost for the CPU, it's important to logically merge things together, such as whole buildings, so that you don't have so many draw calls. I still don't see how you can have that many draw calls.

Too many separated meshes or small meshes will require really bad occlusion settings which will have a high file size and higher CPU cost.

[willow gorge]

society

[unkempt summit]

yeah still too many

considering you are looking at a wall lol

[solemn tapir]

Yeaaaa. Def use overdraw render mode to see what's being rendered in the frustum

Top left corner of the scene tab

You can also enable the visualization mode in the occlusion tab and enable render lines on the camera with that on

Those two things will give you a picture of what's going on.

You might see 200fps and go "that's not bad" but remember this is at basically 720p render res for a single camera. So it's actually really bad.

Ideally you want to be under 200 calls. Realistically under 100

[willow gorge]

i think its this but its okay resource checker has given up as well and is crying in a corner.

and as said, mainly used probuilder

and probuilder does not like merging meshes

[solemn tapir]

Probuilder is fine.

[willow gorge]

no

[solemn tapir]

You can always just export as fbx into blender and merge then export back into unity.

There's nothing intrinsically wrong or bad with with probuilder and nothing stopping you from just sending it through blender real quick.

Regardless, the overdraw render mode, and visualization mode in occlusion culling are good starts to figuring things out and dialing in your occlusion settings.

[willow gorge]

go on, press the export as fbx button

i will watch and laught as unity crashes

probuilder is good, yes

but after a certain threshhold it starts to be... excentric

[solemn tapir]

Doesn't crash for me. What,, you have 4gb of ram?

[unkempt summit]

impressive using probuilder to make that model though

i got sick of it pretty fast, just trying to make a simple room

[willow gorge]

i had to restore the project from backups numerous times because something with probuilder

be it "haha when you open the project all the meshes are at 0, 0, 0"

or "xd, you cant extrude faces anymore"

[solemn tapir]

All the more reason to export your stuff into blender

[willow gorge]

or "okay, so you combined a mesh. what are uv's"

[solemn tapir]

Combining meshes in unity produces a mesh that can't be compressed and isn't ideal

[pallid gale]

also kind of hard to generate lightmap uvs with a Unity mesh file

[willow gorge]

see where the issue is? this should have been considered earlier in the planning and tool evaluation phase. with the knowledge that i have today, i definitively would have used blender for modeling, however past-liechty, present-liechty and future-liechty are not very cooperative

to fix it now would be too much work to justify for basically a big shitpost

[pallid gale]

I don't particularly see what's the problem with convert exporting the stuff now?

[unkempt summit]

i think there must still be other issues

[pallid gale]

and even if you don't want to update the world it would still be good to try so you learn the skill

[unkempt summit]

like just disabling game objects to see what has the most impact is also good

[solemn tapir]

Indeed. That many draw calls aren't to blame on probuilder. Something is up

Overdraw, visualization mode, profiler, frame debugger, toggling things, export one by one as fbx into blender.

No use repeating more for me. Lol. Good luck

[unkempt summit]

it will be good knowledge anyway, optimizing things are fun

[solemn tapir]

If I've learned anything pushing over 1,200 updates to my world, it's that optimization is the bulk of the work

[unkempt summit]

true

worlds can be made so much more quickly if we just ignore performance constraints. Instead over 50% of the time it is spent on making things run in a lighter way

[still pelican]

for people that want to get what you made from unity back into blender,
unity has made an fbx exporter tool

it makes it verry eazy to get everything merged and optimized in blender

[sterile echo]

Guys ,in terms of optimization: i'm making a room with pool tiles, but with a large floor i wanted to make the texture fit as possible the walls like the "OK" circle

I noticed that i cant do it for all walls so the best way that came in my mind was to divide the floor in some parts and set individually the texture (i'm using probuilder UV's editor)

Should it work or its bad in terms of optimization? i dont know if i'm explained well

[deep flower]

I've had a similar problem, and in general there are three solutions:

1. change the texture to follow the UV map [this will prevent the texture from being tile-able though, so if you have to tile an entire room be prepared for a massive texture]
2. edit the UV maps to align with the tiling factors of the texture [mess, and will need to be redone whenever the tiling factors change
3. do not use a texture, instead have a shader generate the tiles on the fly based on where a given pixel is in 3D space

option 1 will consume a lot of GPU memory and probably look bad too because the texel density will probably end up really low
option 2 is a pain to set up, and you'll have to do it again whenever the size of the tiles change
option 3 will render a tad slower[depending on how complex the tile generating algorithm is], but will reduce world download size because there is no texture, and has the added benefit of "infinite detail" [no matter how close the player gets, the tiles won't get pixel-y]

Since I can write shaders, I personally went with option 3, and my particular world performed well enough that the performance impact of generating the tiles on the fly did not cause noticeable framerate loss with my vr setup on a gtx 1070

[untold apex]

chopping up the floor a bit and using UVs to tweak texture placement is negligible in terms of performance. what you don't want to do is add extra materials to solve texturing issues, except as a last resort

[sterile echo]

I've solved with M127's 2nd solution, and by slight changing some sizes of walls, floors etc

Now everything match

[pallid gale]

cool

[sterile echo]

It's possible to enable fps permanent visible in the "built and test"?

Cause the only way i know its to open the vrchat menu during testing

[solemn tapir]

Looking at fps is really only a small part of the picture and isn't the best metric to use for testing. You should be profiling with the profile and frame debugger tools in unity while moving your camera around or changing between cameras. Looking at frame times for the CPU and GPU as well as memory usage and using the overdraw rendering view and visualization mode in occlusion culling to determine what is being drawn. I seldom do any performance testing in game, only testing things like networking in game, or the raw functioning of things. Your fps doesn't really give you any view of why or what is causing your frames to be a certain way, not does it really tell you how well other people's systems will react, it's a blind metric, whereas the profiling tools in unity give you highly in depth look into exactly what has the highest draw times and what is being rendered or operated.

[weak walrus]

I'm a musician and VR chat noob that has recently made a world. I'm trying to optimize it. Noob question: How do i see my statistics window like yours? 🙂

[versed lichen]

Stats button, top right corner of Game window

[weak walrus]

reading your replies has helped me a ton, thank you

my word is a spaceship on a spaceship.... and omg do I have a lot of optimizing to do 😦

right now you can see one ship docked on the other from my main "cantina" room.... Question: Could I put up a wall and occlude the smaller ship so users wouldn't have to render it everytime they look around in the Cantina?

main room

Zeppelin asset thingy

[weak walrus]

😦 I should just make two worlds shouldn't I 😦 😦

[solemn tapir]

Do whatever you want. Looks cool tho dude.

You can dynamically load ans unload assets using area triggers too.

[pallid gale]

a spaceship like that is going to have like the doors be the choke points so you can do it as manual triggers

[solemn tapir]

Indeed. Only one area even needs to be loaded at all. Occlusion culling could probably be leveled well too.

Actually the first screenshot looks kinda open so idk what the occluders would be. Maybe design in some walls. But regardless. Can deff use area triggers n shit and only load chunks. Your file size tho

[weak walrus]

The first screen shot has assets my friend made me in blender (i've never been in blender) so it runs WAY smoother. I first just had that main room, but then of course was like "dur dur why don't i add moar!" 😦

[weak walrus]

thats great info thank you

[weak walrus]

ahhh, so each room gets loaded when a user clicks on the doors to go in each room?

[pallid gale]

yes or just walks past a archway that has the trigger

[weak walrus]

I think the suggestions you made were right: I'm going to do the dynamic loading and unload the first and second room (ships). When a user portals outside the zeppelin will load and the first room the cantina will unload. Thank you again @solemn tapir you really helped

[blissful wasp]

Is there any way to automatically split a mesh into chunks in a program like Blender?
I have this massive mesh of cubes that I need to split into smaller sections of cubes
Goal would be 16x16 grids
And my blender is lagging just switching from Vertex to Face selection in Edit mode

[deep flower]

depends on where the split is supposed to be. so long as you don't want to cut a surface apart, you can just go to:
mesh -> separate -> by loose parts
in edit mode in blender
if you want to cut a surface apart, you'll have to do it manually

[crimson girder]

How many materials is too many for a VRChat PC world?

Im not sure whats the best way to go about this texture wise. Ive made a sci-fi satellite building in blender. At the moment it is one Object. I will be texturing it in substance painter. Substance looks at the materials and creates a Texture set list for each one.

So previously on my first attempt I had the model in four parts, but some of the different parts shared a material. In substance the texture set had them overlapping on the UV's even with the sperate UV's in blender. (Im new to this so likely not doing this correctly)

Is it best to separate the model up by material in blender. Then Create a UV map for each material that can be packed better?

[topaz hinge]

with the amount of materials i see in your blender, thats too much imo

but i see solid colors, so you could easily get away with remapping those colors to a tiny image with a few pixels for each other

[stray oak]

Not sure about your questions but just wanna say that looks super cool and I'm really curious to see how it turns out! Are you open to collabs or commissions? I could totally use something like that for a standalone game I'm making

[crimson girder]

Ah so those colours are just placeholders as in substance ill be using some smart materials and sbar's (Kinda like this but atm Im just throwing stuff around while I figure stuff out) so i cant do the pixel trick.

I thought this was too many.... but my issue was this has been my attempt to fix a problem I had before. >.<

So originally I had the building in 4 parts. Dome Main Front and Glass I planned to have just one UV map and material for each part and use fill masks in substance to separate up the bits like walls, frames, floor ect

Problem was when I did that I had horrible resolution and bleeding across faces even with a big margin in the UV unwrap (I used smart project im still learning this) I knew I could fix this bleeding if I gave those those parts into their own materials. Then substance treats them as sep UV maps and wont bleed them anymore.

But then....as i had the building in 4 parts with 4 uv maps. When I took that into substance it was creating a texture set for each material and with some being mapped to different UV it puts them over the top of each other. (like in last pic i sent)

So I was now at lots of materials with their own UVs so i can get a neat paint in substance XD Can you tell I have no idea what Im doing yet

[crimson girder]

and tysm! I honestly appreciate that! But i think i need to learn a bit more before i start any commissions or anything like that.

[inland bobcat]

How could i lower this?

its huge imh lol

[pallid gale]

you can utilize tiling textures for your Maps so you don't have to uniquely texture everything @crimson girder

[stray oak]

Use VR World Toolkit to figure out what's taking up the most space (likely huge textures, normal maps and lightmaps) then lower the import resolutions and apply crunch compression where applicable

I used that and found I had a ton of 4k normal maps that were practically one solid color with no detail lol. Others were more important that they stay 4k but right away it was super obvious what could easily be shaved off to go from 200mb to 100 for my world

[frigid iron]

Yes what jasono is saying about textures is right, crunch compressive them can reduce world size but from anywhere between 10% and 500% if none are compressed already

[versed lichen]

Use the vrworldtoolkit to see what your build is made out of

[weak walrus]

I am a noob here and in Unity, but someone helped me by telling me to take off the Alpha channel of those textures that didn't need it.

Does anyone know the line of code that can Dynamically unload/load an asset/prefab? I want to make an object, upon player entering the object, unload one asset while simulteaniosly loading another.

[pallid gale]

I don't recall how you do that off the top of my head but you can definitely do that in udon

[blissful wasp]

They aren't loose parts though

[blissful wasp]

I use cyantrigger make a box collider on an empty object mark it as trigger and static
Set it to activate one gameobject and turn off another on "PlayerCollisionTrigger"(?) Change it from VRCDirect to Local
If I messed up describing it here I feel you can still figure it out

[weak walrus]

forgive me, but its the "set it to activate one gameobject and turn off another" is where I'm stuck :(. I have cyantrigger and the collider set up.

[blissful wasp]

Give me a minute to open unity I'll screenshot how I have it set up in Cyantrigger alright?

need to close Blender first as my project there is using like 90% of my ram

[blissful wasp]

GameObject.SetActive twice once for active second for inactive

Or if you're putting your trigger on like an enterence/exit/in-between bit maybe it could just a GameObject.ToggleActive?

[weak walrus]

wow thank you so much, never have recieved so much help in a discord. Yall are awesome

[weak walrus]

I can't seem to change it from VRC_direct. It's grey'd out and unclickable. How can I change this?

[blissful wasp]

Collision Trigger not just enter

also mark the collider as trigger

[candid fable]

if I change the quality in my project setting and restart my project, it is always reset, anyone have an idea why ?

[stray oak]

VRChat has it's own settings that the SDK purposely prevents you from overriding

[candid fable]

ok...

[cinder tusk]

I'm doing some Quest optimisation today, what's the recommend max texture size, light map size, etc?

[pallid gale]

https://docs.vrchat.com/docs/quest-content-optimization

[timber coyote]

How do I make my skybox a smaller size?
Right now my skybox is half my world download size.

[serene sparrow]

crunch it? i assume its a high resolution texture

[versed lichen]

It's probably a 6 sided skybox

[timber coyote]

After some optimizations, crunching and munching.
Now at 25 instead of 50.
That's pretty good.

If I convert my music files to ogg I could probably get that even lower.
But I think I'm good at this point

[obtuse bear]

If you convert music to ogg you will get no smaller and even bigger build size.
Do not do this. Select the music file and in the inspector set the desired compression for it.

[timber coyote]

Eh? Why would it get bigger?
Oggs can be compressed more.

[obtuse bear]

each conversion is unnecessary garbage in a file that compresses very badly.
Unity already converts to ogg when importing, which can be seen in the inspector.

[timber coyote]

Hm, alright.

[obtuse bear]

Quality 50 can be safely set, there will be good sound and good compression.

[timber coyote]

Mine are all just public domain recordings anyways so it'll be aite.

[lilac saddle]

I've been wondering for a while now, I've noticed alot of worlds on Oculus Quest 2 havent been working, an example being box avoid game, where everything is pitch black, everything is still there but I just can't see it, and I haven't been able to find any info about why, does anyone have any idea?

[barren rapids]

Hey so I've got a world with a sun that moves over time, is it possible to like bake multiple shadows based on different sun positions so I don't use a huge real-time light?

[blissful wasp]

I think that was caused by an update to a newer version of Unity
all the world creator would have to do in that case to fix it is just upload it in I think 2018/2019 Unity
If it's not that idk

[timber coyote]

For world creation, would it be better to make a series of modular wall, floor and roof assets and construct my environments using those, and then to GPU instance them into one material?

Because right now I modeled my entire world in Blender with each piece and I feel concerned about the amounts of redundant materials

[twilit atlas]

gpu instancing works only on multiple copies of the same mesh

you likely want to bring down materials by atlas'ing the textures

[timber coyote]

They would be the same mesh if it’s the same wall being repeated

There’s a lot of material redundancy because I use the exact same texture for a lot of things
The only way to conquer that would be to atlas all the textures onto one including all the tiling I’ve been using and that’s gonna be one big package there

[untold apex]

using the same texture for things is good. that's not going to make anything more difficult

assuming the textures are the same, you can use the same material for everything and you're good. even without gpu instancing that's going to reduce draw calls considerably, and static batching can handle a lot of the rest

you can try instancing and profile both options, see what it gets you

[timber coyote]

Oh, if I have all my static stuff marked as static, they’re already on the same material… ohh right. I always forget about static batching

I should be pretty alright then?

[untold apex]

well, you won't know until you profile, but probably. gpu instancing is great, but you do have to be using the same mesh for everything

[timber coyote]

Yeah, I’ll have to take a look when I get home.
I think my world performance is fine but I’m considering future proofing for expansion and building up

I’d rather not be a map that suddenly gets big but sacrifices everything from performance

[fallow drum]

The thing about static batching that nobody seems to mention is that if your objects are lightmapped, they need to be on the same lightmap otherwise they can't be batched together.

Something to keep in mind.

[pallid gale]

so is that a case like manually merging stuff together might help so that they all use the same light map

[fallow drum]

Indeed

I've made a world from lots of modular walls etc and then the same thing in blender from solid components and it droped the draw calls by a lot

[pallid gale]

like I have an acquaintance that's working on a Unity tool that handles automatically merging that stuff in a sensible manner

[fallow drum]

I have on actually for merging a bunch of stuff that I got recently like that that would've been handy.

[pallid gale]

nice

[blissful wasp]

Is there a way to grab a players FPS?
I wanna make it so that things happen based on a players FPS
like if they drop down to 20FPS or lower
switch everything to a super optimized version or teleport them somewhere
etc

mainly in this instance just to make it so if someone turns on the HQ mirror and it kills them it'll turn itself off
maybe prompt them if they were okay with the FPS they were getting and if so turn it back on

[solemn tapir]

Id personally find that pretty annoying. Many people are fine with lower fps. Giving them the tools to mange it in a nice looking menu can be helpful without being forceful. If a mirror being turned on kills people, focusing on optimization, checking overdraw, ensuring things are culling, and perhaps offering a HQ and lq button rather than forcing the mirror to HQ with a single button can be viable.

[fallow drum]

I lived at like 16 Fps in full lobbies when partying until I upgraded my pc

You get used to it xD

[blissful wasp]

maybe prompt them if they were okay with the FPS they were getting and if so turn it back on
If they're okay with it sure fine

[fallow drum]

And fps can dip randomly when people do things so I'd you game is running dine and it randomly turns your stuff off would be anoying.
I'm a big fan of just having a potato mode button for people

[topaz hinge]

making something that grabs someone's fps seems like more work than its worth when you can just optimize your whole world. there's a mirror prefab with 3 quality buttons on it on vrcprefabs i think lol

[fallow drum]

Yea. Idk if there's a direct fps hook bit you could check the time between update events and that would be reflective of the time between frames

[viscid hatch]

I compress my aufio with Audacity and the built in Unity and make it quiet to where you can hear it but not loud because you hear the compression.

[barren rapids]

Is it possible to bake multiple sets of shadows for a scene?

[spice turtle]

Is there any ways to optimize lighting for android outside of baking lights I placed on the map, anything world wise I should be doing? I have one area of the map that just nearly crashes the game and I think it may have to do with lighting

[pallid gale]

well make sure there's no real-time lights whatsoever for 1 and do you have any particularly complicated custom shaders in that area

[spice turtle]

I dont believe so, most items I made with basic shapes in that area, all my textures are compressed too

[pallid gale]

I suppose time to use the frame debugger https://docs.unity3d.com/2019.4/Documentation/Manual/FrameDebugger.html

[spice turtle]

Can anyone determine anything about optimization from this data, this might as well be a foreign language to me

[unique kite]

https://www.youtube.com/watch?v=4N8GxCeolzM

[spice turtle]

Alright well that’s cool and all that I can watch it render frame by frame but how does that show me what is crashing my game😂 theres no “game crashing frame” that shows whats bugging out

[stray oak]

That is a crap ton of draw calls. You want to figure out why all of the things in that gigantic list are being drawn separately and not in groups or at the same time in fewer passes. If you click on one of the steps in that list like "Draw Mesh Cube (37)" it should tell you why it's drawing that cube separately from the one before it. Maybe your objects are not marked as static, or the materials do not use instancing? Maybe you have a ton of separate materials and textures in your scene?

[spice turtle]

it was the static option, went through marked what needed to be static and turn on the occlusion

[stray oak]

Noice. What's the number of calls on that list now?

[solemn tapir]

Just clicking the static box is bad practice indeed. I wish people making tutorials would stop suggesting this. Checking that box enables everything. Batching, occluder, occlude, nav mesh, etc etc. Lots of stuff that can have negative ramifications depending on the project. Then everything in your scene is set to try and batch and your occlusion culling sucks ass.

[spice turtle]

Went from 10k down to 6k

[stray oak]

Dang that's still a lot for quest. Here's a reference from oculus that I keep handy

[spice turtle]

What else could be causing that now I set the proper things to static?

[solemn tapir]

Tons of materials

Also if your meshes don't share lightmaps they won't Bach

There's a lot of reasons something won't batch tho

[stray oak]

Materials on non static objects not using instancing, or having lots of different materials, lots of skinned mesh renderers, crazy shaders or lots of transparent things. The frame debugger should help give you at least some info when you click on each call

[solemn tapir]

I assume your lighting is static too and baked?

[spice turtle]

Yarp

[solemn tapir]

No realtime shadows

[spice turtle]

Looks like 90% of these events are draw mesh

[solemn tapir]

Posting a screen of the entire project can help us

You prob have a ton of sperated meshes

With different materials

[stray oak]

Yeah how many separate materials are in your scene

[spice turtle]

Can you check that easily?

[solemn tapir]

Indeed.

[spice turtle]

Where do I see total used?

[solemn tapir]

Ooof

Yea. You need to be merging a ton of shit

So many separate meshes will lead to bad occlusion culling too, increasing cpu overhead

You can also use resource checker or VR world toolkit to see more info about your materials and number of meshes

[stray oak]

I'm very confused why it says the object is being affected by multiple lights... Maybe the lighting is not actually getting baked here

[spice turtle]

Theres several area lights of different color would that affect that?

[solemn tapir]

Are they baked?

[spice turtle]

Yh

Yah

[solemn tapir]

Post photo

Of your lighting tab and of your light in the inspector

[stray oak]

If you disable those lights does the scene look different? That's how I do a sanity check to make sure my lights baked properly 😅

[solemn tapir]

And the lighting tab?

Setting the light to bake doesn't actually bake the lights

[spice turtle]

Ah I see…

And how do I bake properly?

[solemn tapir]

Go to the lighting tab under rendering

In the windows drop down on the menu bar at the top

You'll want to read or watch about baking probablyz or check #world-lighting as default settings prob won't be best.

[spice turtle]

Ok in that tab whats next

[solemn tapir]

So yeah.

1: too many meshes
2: too many materials
3: lights weren't actually baked

= High draw calls

[solemn tapir]

Well, set everything to baked. And bake it. But the default settings prob won't be ideal so you'll want to read up

Set source for environmental to color and choose a neutral color like a soft gray (artistic choice of your own)

Set environment reflections to probe(if you want, skybox would reflect your skybox onto Everything)

Hit generate.

Wait.

[spice turtle]

Theres skybox or custom

[stray oak]

Yeah scroll to the bottom of that window, lightmapping settings are what you want to tweak here. Then click generate and watch it take 30 mins and make everything look like crap 😅 and then watch a lightmapping tutorial and fix things up and tweak settings until it finally looks good. At least that's how I did it

[solemn tapir]

Lmao basically

It's a lot of trial and error

But you'll want to merge meshes first.

Baking with so many sperate meshes will take more time and then when you merge them later, you'll just need to bake again and prob change lightmap res settings

[spice turtle]

I dont have a probe option for reflection

[solemn tapir]

Ignore that then. It's been a while. I'm walking my dog through a desert rn so I'm talking purely from memory

[spice turtle]

Ok well Ill tackle that later since it will take a while, how do I combine meshes?

[solemn tapir]

#world-lighting is where you'd want to move to for lighting specific questions

[solemn tapir]

Blender

You can do it in unity, but it has a lot of drawbacks if you do. Such as being unable to compress the mesh

[spice turtle]

Will dragging objects into a parent object help it run better?

[solemn tapir]

Best to export things into blender and merge them logically there then export as fbx back to unity

It won't help performance necessarily, but it will make your project easier to manage and will make exporting things as an fbx easier

Things should be logically grouped together. Not just an endless long list.
