world-lighting

[next owl]

you don't want gpu instanced objects to be static anyways. you can technically make them lightmap static but for something like grass you don't stand to gain much from that

[mental charm]

13 min bake now

[mint cipher]

oh?

ok

so you reset the settings and disabled at same time right?

if thats the case try toggling them back on and check time again

[mental charm]

yup

[mint cipher]

and check each object 1 at a time

first try all

if you get long bake time then disable all but 1

and keep going through each one

[mental charm]

it was 100% the grass carpet

[mint cipher]

check those texture settings

send ss if possible

[mint cipher]

well that is certainly an itneresting one

[next owl]

it's not the shader on the grass that's the culprit, it's the geometry

it's a bazillion instances of grass chunks scattered about, and then the lightmapper has to bounce a bunch of rays around them

that's a recipe for pain

[mental charm]

nope not even the grass

its the bushes i have the in the world

'

im gonna bake without and see how they look unbaked, if it looks weird ill just get rid of them

i can always replace them with something else

16 mins bake time no

Now

[mint cipher]

thats better

@next owl any idea why some of my objects are just black and not having light on it?

it is static

[next owl]

do the objects have lightmap UVs?

[mint cipher]

they should but ill double check

but what about matierals?

i made the walls black material

but they are having problems

[next owl]

how black? lightmapping won't really work if your materials are outside the PBR safe albedo range

[mint cipher]

pitch

it was fine before

but its pitch black

[next owl]

you can't bounce light off of pitch black

[mint cipher]

this isnt supposed to be pitch black'

[next owl]

i mean, how black is your black material in textures

[mint cipher]

i just increased it to lighter

[next owl]

have you tried viewing through the Validate Albedo mode

[mint cipher]

so it should work better

but idk why my disco ball is black now

i even deleted and reset it

[mint cipher]

i ammm confused why is it black now

[next owl]

i mean, i tried asking diagnostic questions.
you need to check if the ball has lightmap UVs, if it is static, and if the albedo or other textures are within reasonable limits

if the lightmap UVs were modified recently you may need to rebake. if the material is reflective you will need to make sure at least one reflection probe contains it within its volume.

you also need to make sure that the object itself is set to contribute to GI in the mesh renderer settings

[mint cipher]

i actualy missed this

[mint cipher]

it is static, it has lightmaps and ill check its texture again

[next owl]

okay. from here it looks like that object is almost entirely metallic

[next owl]

have you baked reflection probes? on the mesh renderer for that object, are any reflection probes listed?

[mint cipher]

oh no

i clicked

render reflection probes

oh no

[next owl]

that's not necessarily a fatal error

are you seeing textures on your probes? do they look correct?

[mint cipher]

when lights are off i see it but it doesnt look right

for some reason

now it seems to look right

even though

it failed

?

[next owl]

i have no idea what you're saying

[mint cipher]

allow me to speak english

[next owl]

the errors you're seeing there sometimes happen during bakery operations and they're typically not fatal

[mint cipher]

the textures looked somewhat right when i turned off lights

then i turned it on after trying to bake probes

now it looks right

[next owl]

¯\_(ツ)_/¯

[mint cipher]

seems good to me now

seems like the issue was just the reflect probes

[next owl]

if you're using bakery, you need to bake reflections after baking lighting

for whatever reason bakery will erase your reflection probes after baking lights, and so any metallic objects will appear completely black (because metallic objects don't reflect diffuse light in PBR)

[mint cipher]

thank you for telling me

[lyric heart]

For some reason when I bake AO to Vertex Colors
this effect happens

I think
I'd prefer it if it was more like this

which it sometimes is
Why is it sometimes one way and sometimes another?

[next owl]

your vertex normals might be completely hard on the incorrect ones? or vertices not fused

[lyric heart]

I've checked in edit mode by moving faces and using "merge vertices by distance" the vertices should be fused

[lyric heart]

as far as being hard goes, you can see the blue edges marked as sharp here

[next owl]

are there interior polygon faces in there? like between two of those cubes sandwiched together, are there faces in between them?

[lyric heart]

Maybe let me check
if there are that's gonna be a massive pain to remove manually

Seems no?

[lean whale]

Not sure I can help with you're issue but I'm just curious, are you baking ao to vertex colors in blender? Is that using an addon?

[lyric heart]

Yes baking AO to Vertex Colors in Blender not using an addon
I'm just using Blender 2.93.8 just a feature afaik

[lean whale]

Oooo I had no idea, I'm gonna try this

[lean whale]

Welp mine looks nothing like yours haha

[lyric heart]

What'd you do?

I need every "block" to have it's own quad I can't use planar decimation if that's what you did

[lean whale]

Yea the wireframe looks like this

I did this

[lyric heart]

So nothing different?

[lean whale]

Different from what? From your setup?

Idk how you did it

But mine doesn't seem right either, like Idk why these areas aren't shaded

[lyric heart]

Yeah

unless you're using GPU instead of CPU?

[outer nacelle]

anyone know what to do about this when rendering reflection probes

[modest vapor]

I think this error can be ignored ?

[outer nacelle]

It doesn't give reflections like a working reflection probe does however, like the material with a metal and smoothness of 1 looks flat and cant see light reflections in it, also when clicking on render reflection probe it kinda interrupts the progress bar right away and spits out this error

but your right , i just checked my other world and it gives this error but everything looks how i would expect it too....

[errant anchor]

how do I fix this, using Bakery

[tepid chasm]

Hmm.. well.. my avatar doesn't really get any darker when moving between areas.. though moving an object between the areas does cause the object to get darker (at least in my scene)

Using bakery + light probes, any certain settings or way to set up the probes to better lighten/darken my avatar when I move between those areas? (such as the dark area in the back, my avatar still seems fully bright back there)

[glossy meteor]

what's your avatar's shader?

[tepid chasm]

poiyomi, though I've seen him get darker in other worlds so it's not like he's full on emission :o

and before I added the light probes, he was almost impossible to see.

Maybe I just need to do some more light probes, guess I'll test that out.

[tepid chasm]

Yeah, adding more light probes helped, actually.

Now the avatar does get noticeably darker if I go behind that wall.

I'm assuming when you have a wall (or anything that separates light), you probably want to have light probes close to each side of the wall

[formal spindle]

would edge kissing cause lighting issues later in unity?

[lost imp]

Trying to add Post Processing, but there's no layer available for it.

[sharp robin]

Unity/VRChat doesn't have a designated post processing layers you would have to create your own

Or you could use existing layers that are mostly unused such as TransparentFX or Water

[lost imp]

Yeah, the intention is for water, so maybe I could just do that :P

[modest vapor]

Yes, merge your vertices

[opaque garnet]

any ideas why my lighting looks fine in Unity, but in-game all the interior floors have no lighting at all?

[tepid chasm]

using real time lighting? or baking?

also, sheesh... looks like Bakery's lightmaps can really increase the size of a world by a lot.

my crappy little world at 225 Texels per unity is like 100mb.. but at 100 Texels it's down to 44mb..

[opaque garnet]

Baking; I think it may have been the shader on that material i was using. seems to be resolved for now

[modest vapor]

225 texels is insanely high, so is 100

Indoor should be ~40, outside 10~20

[tepid chasm]

ohh, thanks. was kinda wondering what was a good number. saw someone in a video saying 200 was good. lol

[modest vapor]

[tepid chasm]

😄

that said, I am enjoying messing around with bakery and light probes

except when I go into desktop in vrc after using unity.. and notice I'm still holding down right click when I move...

So at the moment, my world is basically just one big test so I can figure out lighting and what not. Most of my walls are sort of their own pro builder mesh. Kinda wondering if I'd save more file size by making all the walls into a single mesh

[glossy meteor]

don't just combine everything
usually you combine in reasonable chunks to have occlusion culling do the work

if everything is a single mesh, there is nothing to cull

[tepid chasm]

good point, I'm not totally sure on how occlusion and occlusion culling work

[fallow lark]

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

[tepid chasm]

So if a room is mostly square, would it be better to have all the walls as their own mesh, or combine like two walls, opposite corners?

oh that's interesting

so does that basically make it so when you're not looking at certain things you get better performance?

[fallow lark]

https://cdn.discordapp.com/attachments/415412644682661908/663802296781766658/68747470733a2f2f36362e6d656469612e74756d626c722e636f6d2f32656435386634653231323139376630336162396631.gif

basically it stops rendering objects that are hidden behind a wall or another objects

[tepid chasm]

nice

[calm iron]

meow

how to combine mesh in unity ? i have a tool but forget about that

[pale heart]

and idea on how to fix this? everytime i bake my light the uv-maps overlap

[modest vapor]

Did you do what the warning said ?

[pale heart]

I tried but i couldnt figure out where

[modest vapor]

On the gameobject settings, in the inspector

[outer nacelle]

another tip is to crunch compress your lightmaps if you are baking them higher than 1080

[calm iron]

meow

[pale heart]

Suddenly my baking went wrong, i dont know how to fix it, any ideas? in game it looks horrible

[pale heart]

this is how horrendous it looks in game

[past vault]

I'm following a tutorial to do this:

I followed exactly everything but i dont get why i have this

I made my room with probuilder, someone know if that could be the problem?

[supple harness]

And what's the problem? Customizing reflection and lighting behavior on objects .Set everything to static, make baking.

[past vault]

Yea, now i made everything work except the postprocessing stack 2, i set it correctly but still effects of the post processing wont work

[supple harness]

https://gitlab.com/s-ilent/SCSS/-/wikis/Other/Post-Processing

[past vault]

Ok i made everthing work for the second time xD now i just need to figure out how i can make the light be on the player, like, there are no player shadow and the player dont get the light reflection in his body, why?

[supple harness]

https://docs.unity3d.com/Manual/LightProbes.html

[green vault]

baked lighting will not have shadows. but as for lighting your avatar. follow mureiks thing

if youre wanting shadows. best uou can do is mixed lighting. or you can try the projector method

[past vault]

You mean the light probes?

[green vault]

si

[past vault]

I tried with reflection probe and seems the light now bounce on avatar correctly, is it a solution or light probes are better?

(still the shadow of the avatar doesnt show up , maybe i can use a directional light for that?)

[green vault]

use both

light probes and reflection probes contribute to better lighting practices

[past vault]

For the light probe i should make the box large as the room where the light its emitted , right?

[green vault]

youll want probes near lighting

[outer nacelle]

I had this issue happen to me too, I had to export all my assets into a new project with no prior lighting in it, and then re open my scene, re bake lights and then it worked, I know it’s a long solution but I haven’t found a better one tbh

[pale heart]

Thank you! is it easier to bake when im done with all my assets u think?

[outer nacelle]

Yeah probably easiest to set up everything how you want then do the export, if need help with exporting it too just lmk

[pale heart]

Thanks a lot, ill try this!

[tawdry bridge]

yall i lost my inspector

[tight marten]

anyone have any recommendations on lighting a forest with moving leaves? My initial thoughts are to bake the trunks' shadows and then light the leaves in real time/have their shadows in real time, but I wasn't sure if anyone had any good ideas on the best way to do this for optimization.

also has moving grass/foliage as well.

[fallow lark]

not sure if it would be the best solution but here's how Skyward Sword does it basically wiggling a transparent quad with the Shadow baked onto it https://i.gyazo.com/123b3b475207159f4c46c5f13cc4b538.mp4

[spring elk]

ok so im using bakery and everything was working fine and made a few adjustments to some lights and now nothing is baking anymore is there a quick fix to this or is there some rookie mistake im doing to cause this issue because i ran into this multiple times in the past an its getting really frustrating.

[modest vapor]

Clear unity's lighting, clear your GI cache, clear bakery's bake data, save, restart unity and try again

[mint cipher]

my lighting looks good in the editor but not in testing (the first picture is testing and the second is editor)

nevermind, I had 2 lights that I didn't realize I had

[mint cipher]

i got a bakery problem

anytime i use more than 20 texels the bake just gets stuck

for example 30 or 40

fails

anything above 20

and baking at 20 makes the lights look terrible

it just gets stuck at exporting scene

[next owl]

you might be running out of VRAM if your scene is pretty complicated. you could try using bakery sectors to slice up the problem into smaller chunks

[mint cipher]

how do i make sectors?

[modest vapor]

Add the bakery sector script onto an object, place part of your scene below that object, and place that sector object above the bake button in bakery

(I should make a tutorial )

[fallow lark]

yes

[next owl]

...or just read the manual

[mint cipher]

some people have different learning styles

some are better at words. some need video, some need audio

manual could be confusing without visual aid imo

[next owl]

yeah, but like, have you actually looked at the manual? it's not very long

[modest vapor]

It has images too

It's pretty visual

[next owl]

i don't mind helping to answer questions but this stuff is all out there for you to see

[mint cipher]

i might have looked at the wrong place then

because what i looked at had text only and wasnt very informative xD

i probably should've used the link on the store and not some random guide

WIP

[fallow lark]

cool wall pattern

[spring elk]

i need to fix up the corners a bit just trying to perfect the lighting before going any further

[lean whale]

Groovy

[outer nacelle]

really not sure what to do here, that black wall has the same material as the other concrete wall but just comes out black after a bake, yes its static and there are lightprobes in the scene

[next owl]

is that black wall a separate FBX? does it have lightmap UVs?

[outer nacelle]

same fbx, yes lightmap uvs

let me restart unity maybe

restarrting and rebaking seemed to fix it, should have tried that sooner probably

[swift garnet]

Anyone know if theres a way to use https://github.com/MerlinVR/VRC-Bakery-Adapter with shaders other than Bakery Standard? I've baked some SH lightmaps and want to be able to use Mochie's standard, or even my own shaders in Amplify with SH support

[fallow lark]

they are shaders that support the Bakery stuff https://gitlab.com/s-ilent/filamented

That's what I'm asking, I already have shaders that support Bakery lightmap modes

It seems like Merlin's tool to make SH and RNM lightmap modes compatible with vrchat only work with Bakery Standard

[fallow lark]

do not know myself as I haven't tried the SH and RNM lightmap modes

[swift garnet]

[wooden raven]

When I set my own skybox, disable the Directional Light and my Point Light (the only two light sources besides the skybox itself) and then bake the lightmap, it doesn't bake correctly and I'm not sure why. Then, when I undo the change I made and bake it again, it still bakes incorrectly. I'm at a loss. (Feel free to tag me when you reply)

[wooden raven]

Found out it was due to overlapping UV's, but I'm not sure how to fix this.

[fallow lark]

https://docs.unity3d.com/Manual/LightingGiUvs-GeneratingLightmappingUVs.html

[spring elk]

got the lighting done to the way i like it finally started putting stuff in the room

[spring elk]

dose anyone know why my lightmap is breaking when i upload my word to vrc

[versed herald]

in my lighting settings. I know its best to have all lights baked, or most. But should they be rectangle or circle

also for some reason my lights are not baking.
They are set to: Point. Mode-Baked.

Then should reflection probes be baked or realtime, or custom

[graceful tartan]

I see you have bakery. What directional mode did you use when baking?

If you used anything other than none or baked normals there are extra steps you need to take for VRC to support it.

[outer nacelle]

reflection probe should be baked if your baking lights, also how do you mean its not baking, is the progress bar stuck, is the world black?

[versed herald]

no, it finishes, but it still looks like realtime. and i cant find the textures for the bake

[spring elk]

@graceful tartan its just basic settings pretty much besides the samples and resolution

[outer nacelle]

do you have any emmsive materials in the scene that are on realtime?

[versed herald]

not that i know of

[graceful tartan]

My default thing to try is clear the baked data and rebake and test that. 🤔

[outer nacelle]

can you send a pic of the finished world after baking?

[versed herald]

yeah just a minute. building and testing

[spring elk]

ok if that dose not work ill just reset my bakery stuff and give it another go

[outer nacelle]

and if you search for lightmaps in your assets nothing comes up?

[versed herald]

just noticed i sent the msg ot the wrong person

[versed herald]

yeah i found things called "Lightmap" . it just dont look like its baked for some reason. i guess im used to more pixelly looks

[outer nacelle]

yeah if you have thoes then your light should have been baked good

[versed herald]

ok. and reflection probes are set to custom-box? HDR?

[outer nacelle]

i have mine om Type:baked and HDR checked

HDR is a kinda dependent on your world

[versed herald]

what is hdr

[outer nacelle]

hdr just means high dynamic range, i know for a camera it means it just combines several different exposures and combines them, im not 100% but it should be the same for reflection probes becuase they "act" like cameras

heres a comparison https://forum.unity.com/threads/hdr-rendering-and-texture-benefits.903377/

[tepid chasm]

was nice and smooth.. but once I baked it with bakery... (40 Textels), got these ultra jaggy edges..

Anyway to avoid that without cranking up the textels skyhigh?

as a comparison, when I don't set it to static:

[graceful tartan]

Take a screenshot of your bake settings?

[tepid chasm]

that's the settings I used.

[mental charm]

how could i lower my bake times?

[outer nacelle]

I thibk texels is the biggest factor in time for bakes

[mental charm]

texels?

[outer nacelle]

Light map res or texels per unit

[mental charm]

oh

[outer nacelle]

Also you can bake light maps at 4k and crunch compress them to 1080 to save some mb

[mental charm]

How would i compress em

currently this is what my time is looking at after lowering the texels to 20

[pure widget]

turn your samples down tf

[mental charm]

wheres dat

oh i see

what should i put it at?

[pure widget]

half the 500s at least

[mental charm]

alright ill try

gonna place light and reflection probes rn aswell

[outer nacelle]

When the light maps are finished, click on them then in inspector choose 1080 and slide the slider to 100 and choose best quality and then click apply

[mental charm]

Alrighty

Bake time is 30 mins now, which is better than 2 hours lmao (Edit: Its back down to 30 now lol still somewhat rising though; edit again, its going up and down back to back now lmao)

wait its goin up ;-;

Could another possibility be that i have too many point lights, i feel light i do lmao

[outer nacelle]

How many lights you got?

[mental charm]

Ill send a ss LMAO

2 screenshots KEKW

[outer nacelle]

Bruh

[mental charm]

KEKW

[outer nacelle]

What’s your world look like?

Like how compact are the light geographically

[mental charm]

how close each lights are close to each other?

[outer nacelle]

Yeah that wording works better

[mental charm]

I have six seperate "private rooms" aswell with 4 lights each aswell

100% could keep one light on each of these

[outer nacelle]

Ah makes sense, yeah i would say that would help reducing time, could try baking but just turning 1/2 of thoes off and try

[mental charm]

Yeah, ill just redo those and see how it turns out

[mental charm]

Alright so light probes look ridiculous lmao

Alright, got rid of a pretty damn good amount, gonna go through and double check then rebake and see how she looks

[oak breach]

Heya i have really weird thing happening with Bakery, any idea what may cause it and how to fix it? From what i noticed it may be connected to how many stuff light is casted on and maybe their size in lightmap

[mental charm]

Starting bake now, gonna see how long it takes

[oak breach]

For clarity, everything is mesh, no terrains nor trees, everything is static, everything has generate lightmap uv

[lean whale]

Use Progressive GPU instead of CPU

[mental charm]

Baking finished

[outer nacelle]

How long?

[mental charm]

bout 15 mins

wayyy better

[lean whale]

Have you tried using Progressive GPU lightmapper @mental charm ? That should be way faster

[mental charm]

Naw i havent

[lean whale]

It's like 10x for me 😊

[verbal cape]

The default Unity lightmapper has nothing for memory management which eliminated GPU lightmapping for many basic VRC users trying to get into dev. 4GB ram, and a mediocre GPU wont cut it for a lot of content. The simpler the scene the more likely it is to bake but still. For the majority, our savior is Bakery which is way faster. Sure you need an NVIDIA to use it but brand obsession is not the direction you choose when picking a GPU 😉

[tepid chasm]

Figured out my own issue. When I made the pillows, I didn't actually create a seam and unwrap the UVs...

[tepid chasm]

So if you ever got some weird ass lighting on your object.. it might not be properly unwrapped UV wise... (figured that out by clicking the "Show Checkered" part.. and was like, wait... is that because of the UVs?)

[mint cipher]

why is it doing this? all of the lights are marked as important, but it keeps doing this

[pure widget]

bake your lights

[lean whale]

I think you can increase pixel light count in project settings > quality. But note that this will only work in the editor, VRCSDK will force it back to 8 if you build or change the scene etc

To actually use more than 8 lights yeah you need to bake em (and should be baking as much of your light as possible anyway)

[twilit lily]

please dont do that, no matter what. there is almost never a reason to use real time lights

[pure widget]

did you read their whole message

[modest vapor]

There's plenty of reasons to use realtime lights though

[vagrant briar]

Speaking of realtime lights, Im trying to add some on top of my baked light. Am running into an issue where toon lit shaders just appear dark / environment lit and don't get affected by the light in some areas 😦 a sky light sun source would fix this but I am more concerned about why toon lit shaders just ignore most of my lights. In this spot his head isnt getting lit

If I were to move him and the light just a little bit farther right on the image, his whole body would be unlit and just going off environment light like his head is in that pic

[tepid chasm]

They appear dark even with light probes?

Otherwise, if you're just trying to use realtime lights, I think you're limited to 8, haven't really used them enough to be sure

[vagrant briar]

You know what I havent set up light probes yet only the reflection probes so that might fix it if toon lit takes those into account

[tepid chasm]

Dunno for sure, worth trying. All my poiyomi based avatars I've tried in my world with only baked lighting + light probes have been lit up properly

That said, not all avatars are built the same, and might not have their extra accessories and what not anchored to their hip for lighting.

[pure widget]

remove your mods first

lol

[vagrant briar]

After some testing can confirm light probes will fix my issue. Any tips for setting them up properly?

[tepid chasm]

I'd watch some videos. I'd mostly place them around places where the light will change a good bit. Don't be afraid of putting quite a few down, as they don't eat up much resources.

[winter mantle]

For such a long time now I've been going absolutely crazy trying to figure out this issue. Some things are super bright and some are pretty much pitch black after a bake.
It all looks great in the editor, and after a bake it looks kind of good but then I run a test and the lighting gets all messed up and not until then it looks messed up even in the editor after the test. Does anyone know anything that might cause this? (Switched from Bakery to the Built in one, same issues)

Left is before bake, right is after light bake and test run

Looks horrendous

[next owl]

• make sure all geometry you want to bake illumination onto has lightmap UVs
• make sure all geometry you want to bake illumination onto is lightmap static in inspector / contribute GI in mesh settings
• check validate albedo render mode and make sure your textures aren't too dark
• bake reflection probes after baking illumination. this will be especially evident on metallic surfaces

@winter mantle

[winter mantle]

Thank you! Going through your list rn. What do you mean with "Albedo render mode" and where can I find this?

Where?

[lyric heart]

How do I bake the shadows from the directional light?
when I bake it in unity it makes everything darker and doesn't bake the shadows right

I want it to look like this

[graceful tartan]

Make sure that all your lights are static, and the objects that you want to be lightmapped are static also

this is a good little intro to baking https://www.youtube.com/watch?v=VnG2gOKV9dw

[lyric heart]

I just want to bake the light from one directional light

[lyric heart]

Thank you though
I apparently forgot to mark the light as static
thought I did, as I marked it as bake/mixed and assumed it would mark as static too

[lyric heart]

Didn't get the shadowssss

[graceful tartan]

Where all the objects static too?

[lyric heart]

Yes, Static everything

It seems to just bake the ambient/environment lighting
didn't change when I set that to skybox (with the sun source as the directional light)

[graceful tartan]

is the sky light set to have shadows?

and the mode set to mixed or baked?

[lyric heart]

Yes soft shadows

[graceful tartan]

baked would be better

[lyric heart]

Baked too

How do I set the baked shadow angle?

[graceful tartan]

You rotate the light so it points at s different angle

[lyric heart]

Yeah I got that but I mean the setting specificallly "Baked Shadow Angle"
What is it relative to!?
when I change it I see nothing change
there's no icon/gizmo I see that tells me where that's pointing

[lyric heart]

Also again when I bake the directional shadow goes away and idk why
I greatly appreciate you trying to help btw incase I come across differently

[graceful tartan]

I haven't seen that setting before so I'm not sure.
I use bakery so I'm not suuiiper familiar with the unity settings. Alright they're all mostly the same.

If you mouse over it hopefully it'd give a tooltip for what it's for

[graceful tartan]

No worries. Glad to help if I can.
I'm heading to bed now though so hopefully ya can figure it out.

[lyric heart]

Rest well

[coarse moth]

Check if your models have Cast Shadows and Receive Shadows on

Also setting your light to static doesn't do anything to baking process. All it needs to be is either set to Mixed or Baked

[next owl]

baked shadow angle on directional lights is basically softening the shadow so you get a wider penumbra, like on a hazy day

with area lights, the bigger the light source relative to the reflecting surface, the softer the shadow. but directional lights are infinitely small, so that slider is there as a workaround

[lean whale]

Do your static objects have lightmap uvs?

[lyric heart]

They do

[lyric heart]

They should, in import settings I checked "Generate lightmap uvs"

[lyric heart]

Do I need to use a different shader?
I'm using Liltoon for everything in my world

[graceful tartan]

Oh. Yes probably

Use standard

And see how it looks

[lyric heart]

I've tried I hate standard

[graceful tartan]

Generally speaking toon shaders don't get much lighting from the world very much. That's what makes it toon looking

[lyric heart]

What can I use that'll look like this?
needs to be Quest compatible, cutout/transparent support, and maybe emissions too

[graceful tartan]

It might not even be a lightmapped shader

[lyric heart]

Well this one does how I have it setup
Edit: Also just what?
That may be true for default lighting settings for toon stuff but generally every toon shader I have used works fine with shadows for avatars

[graceful tartan]

But I thought the issue was that it wasn't getting baked lighting?

[lyric heart]

Yes this is a screenshot of realtime lighting

Sorry that I didn't make that clear

[graceful tartan]

I'd check that your shader supports lightmapping, because it might not

[lyric heart]

I'm guessing it doesn't support it
That's why I asked what I could use that does

[graceful tartan]

I mean, not to say it again but I'm pretty sure I could get standard to look like that.

[lyric heart]

Perhaps.
I'll try fiddling with the settings of it again

[graceful tartan]

You'd just have to play with the ambient light level a bit so the shadows don't get too dark

[lyric heart]

?

[graceful tartan]

Because one direct light will have pretty harsh shadows. So you might need to maybe turn the emission on the texture up a little so they aren't too dark on corners.or maybe add a second light source from the opposite direction set to not cast shadows to add some ambient light

[slender pebble]

Hello! I've been having an issue for some time now that's been driving me insane, and I was wondering if some one here might be able to point me in the right direction. I have a project with a few different scenes in it, and lately I've been having an issue wherein if I bake the lightmaps for one scene, it glitches out the other unrelated scenes and some texture maps have huge black splotches all over them. I'm using Bakery, for reference.

I can't for the life of me figure out what is causing it, however, but it's incredibly taxing to have to re-bake lighting every single time I swap between scenes.

[lyric heart]

I think there's a setting to output the lightmap to scene specific folders
Try that

[slender pebble]

Hrm. Gave that a shot, still having the same issue.

[lyric heart]

Seems I already did

Is there a standard shader with backface culling off?

[glossy meteor]

a shader like filamented can

[graceful tartan]

filamented or Mochies can

https://github.com/MochiesCode/Mochies-Unity-Shaders/releases
https://booth.pm/en/items/3250389

They're both great shaders

[coarse moth]

Definitely recommend Filamented. Its very optimized and makes the lighting look better.

[outer aurora]

ORL Standard is also worth looking at c:

[graceful tartan]

It's also very preformant on quest too so you don't even need to swap it out most of the time.

[fallow lark]

that's good to know as I don't have a quest so I wouldn't be able to test that so it would like be okay to have all the materials on the map Be filament on a quest

[half herald]

Jetstreamsans

[graceful tartan]

Yup. Out of habit I remove all the heightmaps though since Im told that heightmaps don't preform well on quest.

But I also don't have a quest to test that XD

[half herald]

I do

[fallow lark]

wish there was a easier way to Ballpark Quest performance if you don't have one but that would be very difficult given the architecture differences

[graceful tartan]

Yea, even emulation I don't think would give a great idea of the preformance

[fallow lark]

which is quite frustrating as I want to try my hand at cross-compatible development as I have Quest Standalone friends

[green vault]

someone had like a specific list for settings in unity projects that would simulate the performance of what a quest 2 on stock would give. i think they set the resolution of the camera in unity to the same as a quest 2 and somewhere in the profiler, you could custom set it to use the same specs instead of using the editor window and your pcs direct resources

[graceful tartan]

Might be a good start, but wouldn't be exactly comparable since the graphics logic on the mobile chip in it just works differently to a PC one.

[green vault]

itd also look different, but that list i was talking about had like everything you could do to replicate what a quest saw, without one plugged in

[verbal cape]

as long as you are baking, and using a supported shader, and no post processing it should look close enough. I have no Quest, fk that paper weight. Yet 3/4 of my clients are Quest users that love the product they receive. Unless you are building something complex with UI and interactions that are not universal it should never be a huge problem. Filamented is a nice shader for Quest support. Not too good with reflections but it's my go to shader.

and I build PCVR and Quest identical. Maybe include PP in PC but rarely

[outer nacelle]

I think it would be cool to have a tool like websites and chrome dev tools have to emulate mobile performance vs desktop but for vr, would definitely be a good help 🤷🏼‍♂️

[lean whale]

Yea that would be amazing. I'm sure lots of people have tried though, and if anybody made something decent it would be a very popular tool

[fallow lark]

very hard to make a cool like that because you couldn't emulate the the graphics performance of The Quest from a PC because the quest renders differently than a pc gpu

[outer nacelle]

of course, just a cool idea

[vocal grove]

Does anyone know if there is a possibility to exclude a single baked light source from adding their data to a light probe group?

[verbal cape]

what? Light probes are meant to provide lighting data to dynamic objects. The data they gather can only come from a lightmap. No lightmap, no data, no light on the dynamic object. Solution: dont place a light probe around that spot.

[lean whale]

I'm not sure you are understanding the question here. Just as an example, say you have a room with a bunch of red and green lights. Assume (for whatever reason) that the creator wants to bake all of the lights into the lightmaps, however they do not want the green lights to be baked into the light probes- so dynamic objects passing through should only be hit by the red lights, despite them seeing green lighting in the environment. Changing the probe placement will not accomplish this

I know reflection probes have culling layers... kinda surprised light probes do not

[modest vapor]

Why would probe placement not work ?

[lean whale]

I think as a hacky workaround maybe you could make a copy of the scene, delete the light sources you want to exclude, bake the lighting and probes, then use copy the probes back into the original scene? Lol

[lean whale]

Because probes still need to be in correct places to account for other lights

[modest vapor]

Ah, in your example I was under the impression that you only had green and red lights

[lean whale]

Well yes that's what I mean. How could you move probes to only get rid of the green lighting? For the sake of this issue let's pretend they are right next to the red ones

[verbal cape]

^ if you only want light from the red light place the probes in the red light area 🙂

you wont get green spill off

[lean whale]

Again for the sake of this issue let's pretend they are right next to the red ones

[modest vapor]

Unless they literally intersect, you can place your probes correctly

[lean whale]

But then the probes would have both red and green light embedded in them... right?

[verbal cape]

if they are intersecting and you fail to place the probe in the correct spot yes, it will have both datas

but given you can see the lighting, failure to place the probe correctly can only be if you are using automated software

which you really shouldn't do unless you have a MASSIVE world or cant be bothered to care

[lean whale]

Huh. I'm wondering if I'm not understanding probes correctly then

[verbal cape]

normally you place probes where light transitions and at a source. this will result in a realtime like effect for dynamics. but they gather light based on the baked data so if a probe is placed in an area that is red it will only use the red data

the green and red only bleed together when overlapped and even then unless they share the same place there is a point that will only be one color

[lean whale]

Ok I'm tryin to get to the bottom of this lol. So I just baked this scene real quick- everything is static and baked except the sphere. With your solution, where would be the correct place to put the probes so that the sphere only gets the red lighting?

[verbal cape]

in the darkest red area

[lean whale]

But every bit of this plane is being hit by both lights? And anyway if the sphere is directly under the red light, won't it still be dark?

[verbal cape]

or directly inside the red light but that will give a really red dynamic light

[lean whale]

Yeah that would provide incorrect dynamic lighting, and not in the way we want

[verbal cape]

its already incorrect lighting to want to exclude a light source

[lean whale]

That's a very different result on dynamic objects than if the green light wasn't there

That doesn't mean that making it more incorrect is acceptable though

Depends on what is wanted, in this case it's just the exclusion of a source and not also incorrect lighting from the active sources

[verbal cape]

... its either right or its wrong. What you are requesting is wrong. Perhaps if you gave a reason why the light needs excluded, what scenario could you possibly have?

[lean whale]

I'm sure there are reasons, but that's besides the point. Like what reasons do people need culling layers on reflection probes for? Idk exactly but they are there for a reason and people definitely use them

[verbal cape]

we arnt talking about reflections, we are talking about lighting, its just not realistic and difficult to compute lol. Best solution: Use a single real time light set to ignore the player layer for the light you want to not effect the player.

one rtl wont drop you but 1-5 fps at best

[fallow lark]

and honestly that would probably look weird on avatars using realistic shading having it be red when it's standing in between the two lights like that

https://i.gyazo.com/76bb3fdbaf1c4edd3f726a839c31387a.png

[verbal cape]

Its definitely an odd request Jason. Try my idea and see if it fits your needs.

[lean whale]

I mean this is just a scratch scene to illustrate the problem. In an alternate version of this problem there might be 100 green lights and realtime wouldn't be an option. I'm sure there are good reasons out there for doing something like this, none that come to mind immediately, but like, gamedev is full of weird hacky tricks that aren't "realistic" but achieve a particular stylized look by defying certain physics and things. I don't think light probes with a layer culling mask is such an odd thing to conceive

And it's not my problem in this case, just one that I'm curious about and want to help with

[fallow lark]

honestly if you were to do that trick I would think your map was broken lighting wise

[verbal cape]

^ so would everyone else. cant wait to see what magic they pull tho

[lean whale]

Well I'd assume it wouldn't be applied in such a simple way that looks very obviously wrong. But yeah Idk the particular use case here

[fallow lark]

personally I can't think of any scenario that would be suitable with vrchat

[lean whale]

Just curious, what is your use case? Why do you want to exclude a light source from the probes?

[fallow lark]

because you have to accommodate a wide variety of avatars so you need your lighting to look good to a realistic Avatar

[verbal cape]

well as much as you got involved, you should message the OP and offer to assist 😛 make it a collab

^ with respect of course, you put in a lot of effort to clarify

[lean whale]

Well, I don't have all day to work on other people's problems but I do like to dig into the nitty gritty on weird things like this 😅

[vocal grove]

I have a scene where a light source from a campfire would shine light, the intensity is enough for the dynamic objects (avatars), but not enough for the leaves of a tree a bit higher in the air (not accurate, but it looks better when they are receiving a bit more light). So I added a extra light with the same colour that only is able to light up the leaves and set it to a slightly higher intensity, only problem being, that this light also adds more light to the probes

[rotund ibex]

How can I bake translucency?

[remote prawn]

why is there a shadow here? It shouldn't be casting/receiving shadows at all

also the light shadow type is no shadows

[remote prawn]

Ok so I fixed it in Blender by using the "Clear Custom Split Normals Data" option

[next owl]

double sided GI. you might need to put a light or an emissive element inside the housing

[glad rock]

So my world in android is getting crazy lag when I look in certain directions, I believe I may have narrowed it down to lighting. All my lights Ive placed are baked, is there any world light settings I can change to help optimize it? Theres no windows or anything so I’m using default skybox

[verbal cape]

you can set the tag on the lights to editor only. This will ensure that if your bake failed that they dont make it into the build. Lightmaps wont be causing your issue. Not having occlusion culling will. having real time lights will, the list goes on. Using the profiler will help sort out your low fps.

[tardy rivet]

Is there a way to get Bakery RT Preview to look more like the actual render?

RT:

Render:

It's super different

[tardy rivet]

So after separating the walls into separate meshes and the desks as well, it seems to work better - though it's still a bit stretched. is there a better workflow for doing this? Like is there a better way to get from the preview to a full bake?

[rotund ibex]

so I'm modelling my childhood home

How can I get this lighting into unity?

[fallow lark]

you pretty much have to do all your lighting setup in unity

[tardy rivet]

Any idea why these weird distorted lines are happening here???

[green vault]

if you want a sand traced bake like that. youd basically disable all denoising the lightmapper does

[green vault]

overlapping uvs are cross talking over each other. light

map padding may fix issue

[tardy rivet]

Map padding?

Why would the UVs overlap?

[lean whale]

Yea it doesn't look like overlapping uvs to me, or else the checkerboard pattern wouldn't be consistent across that plane. Idk what it is tho

[graceful tartan]

Do you have a heightmap on the texture?

Or a normal

[green vault]

uneven uvs

so like. imagine having a pixel shared accross 2 different surfaces

[tardy rivet]

but shouldnt the UVs been consistent with the geometry??

[tardy rivet]

there is a normal

[graceful tartan]

Does it have a seam that runs along that part? Just looks like a dark crack between some boards to me. Unless it's something else in the pic your talking about

[vagrant briar]

If this is a blender file then unity can just import your lights as well automatically

[tardy rivet]

There's one seam in the direct middle, but not as many seams as light glitches

[graceful tartan]

Have you got the "generate uv light maps" check in the import settings for that model?

[next monolith]

First is my editor, second is in-game. What is goin' on here?

[graceful tartan]

Have you got ligbting enabled in editor? These the little light bulb kn the top bar

[next monolith]

The editor view is the one that is correct.

It's the ingame view that is the problem

[graceful tartan]

But the game is the final result, so you gotta ask why the editor doesn't look the same

Hence my question

[next monolith]

Yes. The lighting is on

[graceful tartan]

Just to confirm, we're looking at the fact it's darker in-game right?
Are your lights baked or dynamic?

[next monolith]

Purely baked

And yes. Namely that big, black wall

I changed the material of that building to a mobile shader and it did fix it, but I want to understand the why rather than just accepting it

[graceful tartan]

Hmm. If you test it in editor with cyanemu does it look too dark then too?

[lean whale]

What shader were you using on the wall? And what kinda lightmap directional mode?

[next monolith]

Directional. I'm using a UVFree shader

[mortal loom]

Hey, I've been having some bakery issues. I figured I would get a better lightmapper since the progressive lightmapper has some serious noise issues at lower light levels. Also, the GPU features break half the time.

However, there are some new problems (as expected):

1: I get fireflies. Bakery's documentation suggests to use a stamp tool to remove the sun from an EXR/HDRI. However, how? I have been searching around for a guide on how to use photoshop to remove the sun, but it's all photo-related. Also, for such files, there is not a 1:1 for pixel brightness to HDRI brightness. I cannot see how I can interpret what the appropriate amount of brightness should be when using a stamp tool.

2: I get seam errors. Even "fix bright seams" doesn't seem to fix anything. In fact, it seems to introduce other issues:

The progressive lightmapper works far better than bakery, so far. This is at odds with everything everyone else has said about bakery, so I can only assume that I simply need to continue tweaking my settings. However, it is not clear what the right numbers are for this.

look at this mess, like wtf. It's literally the inverse of what a lightmapper should be showing.

[fallow lark]

https://gitlab.com/s-ilent/SCSS/-/wikis/Other/Light-Baking

if it helps a text guide for Bakery

[mortal loom]

Thanks. I don't see anything in there, however, that is in greater detail than bakery's official documentation: https://geom.io/bakery/wiki/index.php?title=Manual

[fallow lark]

I might suggest making like a test that's just like a cube and a plane to make sure you don't have like your install somehow messed up or something

or weird shaders

[mortal loom]

It's all using the standard shader

[fallow lark]

okie dokie just thinking of ways to eliminate variables

[mortal loom]

yeah thanks for the help and such

I'm tweaking things and just baking over and over to see what happens. I think a big issue is indeed the HDRI that is being used. I didn't realize that bakery freaks out if an HDRI has sunlight in it

However, bakery just says "google it" when it comes to how to remove spots from an EXR file

Like, my original bakes from bakery only had small problems (fireflies, brightness at seams) and now it's just horrendously broken.

[fallow lark]

maybe you could use a different Sky Box for the baking?

[mortal loom]

That won't really solve the "shadows are white, bright areas are black, blue stripes in random areas" problem, unfortunately. Here's what the default lightmapper looks like. It's so much better than Bakery. It feels like money wasted.

If bakery freaks out at a simple HDRI then different color values in the same format shouldn't drastically break things, unless the lightmapper is fundamentally flawed, but I don't think that's the case.

[fallow lark]

yeah I'm wondering what is up as like Bakery works fine for everybody else who tries it

can you try like a baked with the default Skybox

[mortal loom]

If only those people could come out of the woodwork

What I have right now is the HDRI inserted into an empty with a "bakery sky light" component, and I have the skybox disabled for unity's built-in lightmapper.

Yeah. every attempt I make to bake using bakery just produces literal inverted lightmaps. it's absurd

It worked at first. Now, it doesn't, even with default settings.

literally inverted

[fallow lark]

question maybe try making a new project with only Bakery in it

to make sure you don't have like some scripts somehow interacting badly?

[mortal loom]

zero scripts in there right now. nothing but mesh data for now

(except for a VRC Mirror script which is untouched)

I've kept all custom scripts and materials in a separate project. But yes, I'm going to have to make a new project to see what's up. It could be that unity just doesn't handle Bakery correctly in this version.

[fallow lark]

I don't think it would be that one because literally everybody is using the same Unity version

[mortal loom]

I would hope so

For some reason, I am gloriously subverting expectations. I hate being the odd one out lmao

(experimenting with fresh project)

[lean whale]

Does it look correct if you just use a different hdri or disable the sky light and then bake?

Op sorry

[mortal loom]

standby. computer processing

[mortal loom]

I'm removing the HDRI, putting in just a solid color, with a single directional light with the bakery direct light component on it. I'll see how this goes

no skybox, directional mode off, render "full lighting" and bam, inverted shadows. I'll try this in an empty project to see what happens.

just using simple settings

everything identical in the new scene. now it works. RIP

I have no idea what went wrong

I wish there was some sort of "reset everything" button in bakery. or maybe I can just uninstall the whole thing

Ah ha. OK. now I'm back to where I started. It looks like bakery was freaking out over its own lightmaps. Once I told bakery to delete the data, it got back to the original set of symptoms I'm dealing with, which is better tbh. However, I am still getting fireflies, even without an HDRI

[next owl]

what is your bakery light source component and how bright is it?

[mortal loom]

good question. I'll check once my computer is done

[next owl]

getting fireflies when sampling an HDRI with very bright hotspots (like the sun) is a common problem; often the way to get around it is to clamp your maximum ray brightness

[mortal loom]

oooh. Now this is interesting. Where would this setting be? This sounds like it could be exactly what I'm looking for 🤔

[next owl]

you'd have to do it in an image editing program. literally you'd just be throwing away exposure values above whatever arbitrary threshold you pick

[mortal loom]

Ahh yeah, that's what Bakery's manual recommended. Unfortunately, I haven't found a good guide on how to do that :/

Normally I'd just stamp it out in photoshop, but since pixel brightness isn't 1:1 with HDRI's, I feel like there's a better way

[next owl]

photoshop kinda sucks at HDRIs

you could probably do it in the free version of fusion that comes with da vinci resolve

[mortal loom]

this is weird. it just reversed my lightmaps once more hahhaa, even when I had it clear out the original lightmaps first

[next owl]

never seen anything like that in bakery. i wonder if it's some weird NaN shit from your HDRI

[mortal loom]

Maybe, but this is without using the HDRI at all

but it does look to me like it's doing some kinda weird overflow thing where all the values are getting inverted

[next owl]

bakery could have already stored what you had as the environment map, try deleting all bakery data from the menu

[mortal loom]

so I selected "clear all baked data" before rendering the above picture

WAIT. scratch that. there's a third menu option.

I didn't select the third option. Trying after this now.

OK. better. tighter fireflies. To answer your question @next owl I have one directional light with an intensity of 1.84, in realtime mode. I'm going to set it to mixed. Should I maybe reduce the brightness to something like 1?

[next owl]

the bakery light component is the only thing that's going to determine the brightness of the GI solution

[graceful tartan]

Yea, If you haven't already you need to add a bakery light component to your directional light and it should give you a match settings button.

[mortal loom]

Yeah, there's already one there

I had it match settings and such

[next owl]

try starting at 1.0

directional lights typically have no falloff

[mortal loom]

Giving this a go. I set the bakery direct light to 1.0

(with no HDRI for now)

This is with an intensity of 1.0. Hmmmmmm

I'm going to try again with "dominant direction" maybe?

[next owl]

are you passing the light through a lot of small shadow casters? trees or something like that?

[mortal loom]

no trees or anything like that

empty environment except for this one house

so far, unity's progressive lightmapper is whipping bakery rather thoroughly. So I can only assume that I still have the wrong settings

yeah. bakery juuuust isn't doing well, hah

[graceful tartan]

Might be a dumb question but just to be sure, you have generate lightmaps checked on the model right?

[mortal loom]

Yeah, I have "generate lightmap UV's" checked for the fbx import settings

[graceful tartan]

How many samples are you baking at?

I've never baked with an hdri myself. Generally just put a directional light where the sun is in the skybox and call it a day

[mortal loom]

I'm doing all these bakes without an HDRI. I'm using 5 bounces and 16 samples right now

[graceful tartan]

Oh ok. hmmm.

[mortal loom]

Also, I forget: "texels per unit" which direction is more or less? What does a "unit" mean?

[graceful tartan]

I believe it's one unity of distance in unity. Idk if there's a direct unity it converts to

[fallow lark]

basically like how many pixels across like a meter would be on the light map

[graceful tartan]

What is your texel density?

[mortal loom]

Ohhh I see. so texels per unit is texel density then huh? I was doing 20 per meter

Maybe I can overshoot and then compress the lightmaps

Though, unity's progressive lightmapper seems to entirely lack this issue

[graceful tartan]

I normally go for 30 texels but I know people who do 5. It depends on what your going for I guess.

[fallow lark]

like 20 should be fine for like an indoor map

[mortal loom]

It's a fairly "small" house at around 300 square meters, scaled by 1.1

[graceful tartan]

If you select your directional light try turning the samples up maybe?

Oh and what denoiser are you using?

[mortal loom]

I have 16 shadow samples right now. Using Optix 7 for a denoiser (I am using a 3090)

[graceful tartan]

Hmmm ok idk about optix..I generally uaenopen image denoiser.

[mortal loom]

I might do that then 🤔 I'll give that a go

[graceful tartan]

But I have a 1080

Worth a try tho

[mortal loom]

I know that Mr. F was strongly advocating for optix AI denoiser and stuff

[graceful tartan]

Ahk

[mortal loom]

like, right now, my assumption is that I'm mucking it up pretty badly and I just need to work out the kinks. Because from what I've read and seen, it's not good enough to say that Mr. F understands baked lighting hahaha

[next owl]

for a complex interior you want a pretty high texel density

[graceful tartan]

I feel like I had more issues with optix 5 that I liked so I used open image

[next owl]

i guarantee you that bakery is an improvement over the built-in lightmapper

dude knows what he's doing

[mortal loom]

I'm assuming "Tile size" has to do with the size of the array fed to the GPU?

[graceful tartan]

Yeh something like that

[mortal loom]

OK! I maxed that bad boy out then

I'm gonna justify the money I don't have anymore somehow

[graceful tartan]

All I know about that is the hover tooltip

🤣

[mortal loom]

thanks for the help again btw. you guys are asking stuff I didn't think about

[next owl]

tile size will not affect quality, it's an optimization for speed

[graceful tartan]

Bakery is indeed great. It's not without it's issues sometimes which can be annoying though.

But when it works it ✨ works✨

[mortal loom]

100 texels per unit, optix 7. I'm going to stick to 100 and change to open image denoiser

[fallow lark]

like when you get to really big Maps the speed difference is tremendously beneficial

[mortal loom]

I'm also using Xatlas as a packer and unwrapper. Maybe I should not do that?

[graceful tartan]

Yea I feel like that might be an optix issue. I feel like it used to give me random bright spots. 🤔

[fallow lark]

that shouldn't have a big effect on it

[graceful tartan]

Xatlas is normally good.

Sometimes it has given me issues with uvs bleeding where the default unwrapper doesn't.
But I normally use xatlas until something starts annoying it

Probably issues you could fix with fixing thrbuv unwrap settings for things but I'm lazy

[mortal loom]

I switched to "indirect" instead of full lighting. not sure if it'll make a difference or not

this is same settings as before, set to "indirect" looks like it had no effect. maybe more samples for the directional light I guess. I'll try that

[graceful tartan]

That's on open image?

[mortal loom]

I think it was? :S actually I'm not sure, because bakery keeps resetting the window and all my settings each time

I'll try that first

open image denoise. same deal X_X

doubling the GI samples in the bakery settings and trying again.

[graceful tartan]

Aaaaaactually

Could you check the scale on your object?

[mortal loom]

so all the child objects are scaled at 1

the parent object they're all under is scaled to 1.1

bounces and samples maxed out, 100 texels per unit

[next owl]

ok. what are all your light sources atm? just the single directional? do you have a bakery skylight as well?

[sharp robin]

@mortal loom Does your map use any emissive materials?

[mortal loom]

Oh crap, I do have a bakery sky light as well. maybe that's causing the problem.

@sharp robin no emissive materials for now

[next owl]

if you're using a sky texture in the bakery sky light, and the texture has a sun in it, that is your problem

[mortal loom]

yyyyep. I think you are exactly correct. I disabled the skylight and now things look sane. It looks like, indeed, I will have to go into an EXR editor and clamp the brightness somehow

[fallow lark]

glad we were able to finally sorted out

[mortal loom]

I have noooo idea how to do that.

Also: How do I exclude objects from being lightmapped in bakery? for instance, what if I want them to contribute to global illumination but only receive lighting from light probes? It lightmaps every object right now.

[next owl]

just clone stamp man

photoshop can easily read a 32 bit HDR or EXR file. clone stamp the sun out, that's it

[mortal loom]

Is there a way to adjust brightness settings so I can see the full range of pixel brightness?

as in, without compressing it all down to the brightness depth of the monitor

[next owl]

use an exposure adjustment layer

[mortal loom]

ohhh duh. yes.

that makes sense hahaha

[next owl]

you aren't going to be able to see the whole exposure range at once

[mortal loom]

yeah definitely not

[next owl]

use the exposure layer to stop down so you can see the sun, paint it out, then delete the layer and save

[mortal loom]

goooood call. I'll see how well that works. I suppose I could just add an adjustment layer to clamp the brightest values. or is it more an issue of it being that the sun is a bright POINT light source? like it's way too concentrated or something

thanks for the tips guys 👀 I'll report back if I get this working!

[fallow lark]

glad to be of help and your screenshot without the Skylight looks a lot better so progress is definitely being made and I might suggest putting the density back at like 20 so it doesn't take like too long to render your light Maps while you're testing

[next owl]

this issue is common to all CGI rendering. when you have a SUPER BRIGHT pixel next to something much darker, and you have a limited number of rays to shoot around, you're going to get sampling errors that will manifest as either fireflies or aliasing in the final image

[graceful tartan]

Well that was an adventure

Glad we got it figured out.

All the help homies I see helping often joined in 🤣

[mortal loom]

@fallow lark @next owl @graceful tartan whoooaaa. yeah. that skybox thing solved everything. I just clone stamped out the issues in photoshop. I'm aboard with this fully now

[graceful tartan]

That looks really nice!
I've not done any bright daylight scenes like that but it looks really good.

You can probably turn you texel density back down after that too, unless you want it to take forever to bake and then turn the res down at the end or somethin.

[mortal loom]

yeah probably. I cranked it to 200 hahaha

I might just compress the lightmaps in photoshop or something

I like how photoshop handles aliasing

[fallow lark]

awesome

[mortal loom]

What's interesting to me is how it not only fixed fireflies, but how fireflies + (lots of other weird things I saw) were linked to having those few overly-intense pixels

so oddly darkened areas, weirdly blocky bits

[graceful tartan]

I guess it would be taking that one super bright pixel as the brightest allowed point, which would scale all the other bright parts way down in comparison.

[mortal loom]

Oh hey, I have another question: How do I exclude objects from being lightmapped? For instance, if I wish to use light probes + a proxy volume for some of the smaller dynamic objects, and I do not want a lightmap on them. In Unity's progressive GPU renderer, I can simply declare that I wish it to be light probed instead of lightmapped

[graceful tartan]

You could just not set them static.
Or in the settings set the 'scale in lightmap' on the objects renderer to zero if you still want it to be casting shadows but not lightmapped.

[mortal loom]

Ahhh yeah. OK. I could just adjust my lightmap scale that way 👀 I'm glad to hear that the built-in lightmap size settings carry over to bakery

[mortal loom]

Also: is there a way that I can set a reflection probe to only reflect the skybox and nothing else? Like in the case of an interior with its own set of probes, surrounded by an exterior which would just have a skybox reflection. Right now, what I've got unfortunately reflects everything.

Got it! I had to set the "culling mask" in the outdoor probe to be lowest priority and only set to the "environment" layer. that way, it doesn't reflect the things within. I'd imagine this applies to any custom layer too.

[simple sinew]

Anyone know what could be causing these strange dark spots?

[sullen solar]

anyone experience random lights appearing and baking? there's only 1 light source in the scene (top left)

[graceful tartan]

Feels like a lightmap uv issue?

[simple sinew]

Maybe

Trying to figure it out in blender

[round moon]

is there any emissive texture on the atlas?

or i mean, is it setup to be emissive soon but you don't have the emissive parts showing yet

as for the corners check to see if you got some inverted normals that you can't see but are blocking the light from hitting the outward facing normals

[glossy meteor]

looks like overlapping uv2

or flipped faces and we see some dark outside

[mortal loom]

when you load up the FBX, do you select "generate lightmap UV's"?

[ionic kernel]

last shot reminds me of one of those minecraft raytracing showcases

really nice lighting

[simple sinew]

Usually yes

[mortal loom]

thx!

[mortal loom]

What I usually do in that case is investigate the individual polygon on the lightmap and see what it's mapping to. if it's just oddly pitch black, another guess I may have is that it may have to do with how the vertices are connected. I had some weird lightmap issues in the past and it was because I had identical faces filling the same set of vertices. It was something blender couldn't pick up, and I just had to manually delete them. I'm wondering about the vertex connectedness you have because there's that seam on the lower left of my crop of your screenshot. I'm guessing that the vertex in that corner isn't attached to the one continuing the crossbeam above

er not lower left. upper left, but lower left of that vertex/corner

[unreal halo]

Is there a way to apply a directional light only to the players in a world? :)

[graceful tartan]

Yes, you can set which layers the light affects in the culling setting on the light itself. Just set that to the player layer.

Just be careful with dynamic lights on players, using it alaringly as it can be rewource intensive if you use too many

[round moon]

again just to be sure (some people are unaware of this setting in blender) have you checked the face normals with this? :

[hearty wren]

well

[sturdy ether]

Does LTCGI only affect supported shaders / lightmaps which means using a real time reflection probe to affect players or can it affect light probes as well?

[patent heath]

light probes cannot be modified since these are baked, reflection probes can tho, but it can be very heavy depending on the resolution, and ye i think it can only affect its own shaders
Light probes and lightmaps are static

[sturdy ether]

That's what I was guessing after visiting other LTCGI worlds where it was also affecting my model. Thank you.

Thought maybe it was also baked as enlightened realtime gi.

[patent heath]

nah

if it was affecting your model it might be realtime lights, reflections or that your shader supported it

[sturdy ether]

Currently there's only one realtime reflection probe around the main viewing area at the default 128 res. Going to assume that's fine, if not I'll just lower it.

[patent heath]

depens on the update mode, i don't know how are these named but one updates side by side each frame, another probe by probe and another just updates everything for every frame, this changes a lot on the performance

[sturdy ether]

I'll do some testing, if it's not performant enough I'll omit the RT probe.

[patent heath]

i think realtime vertex lights will work well
but the world shader should omit them since these work better on meshes with a higher polygon density like avatars or props

[green vault]

so ltcgi method to effect players is via the global illumination method, which is basically editing a single light probe that effects the whole world. but as someone who uses their own custom lighting methods, i think light probes or linear space projectors would do a better job at looking “realistic”

a more intense method would be to use a realtime light, but set it to only render on player layer to be as optimized as possible and basically summarize the color of the rendertexture used

[patent heath]

also set it as not important

[green vault]

that too if using mixed

or multiple rtlights

[earnest mantle]

Hello, does anyone know why whenever I build and run the game in vrchat the baked light from an emissive material disappears?

Before:

After:

[lean whale]

Not sure, what shader are you using? And it looks like the other light in the top left corner is also not appearing- is this just happening with the emissive material or with all of the lighting?

[earnest mantle]

All shader's I've used are Unity's standard one

I may have just realised, it seems that the light isn't retained on only the single mesh* that is the building.

You can see on the right the other materials objects are being lit fine

This is what it's like normally before pressing build&test

[lean whale]

Huh I'm confused sorry. Do you mean that it disappears from your scene view after building too?

[earnest mantle]

Yeah, it's like it's deleting the lightmap

[lean whale]

Ahh ok. Are there any errors when that happens? Does it also disappear if you switch scenes and then switch back?

[earnest mantle]

Lemme check

Aha it does

Do you know if that actually means anything?

[lean whale]

I'm no expert on this, but I might try clearing the baked data for the scene and even manually deleting lightmaps/lightingdata assets that it is using, then rebake everything

I feel like I've had similar issues when I've renamed and duplicated scenes and they're referencing stuff in another scene's folder or something

[earnest mantle]

ah ok I'll give that a shot

I've cleaned a bunch of stuff up and now the lightmap stays when I swap between scenes so that's a good sign

🤞 this works

It's works!

[lean whale]

Great 😄

[earnest mantle]

Thank you so much

[lean whale]

No prob I'm glad it worked

Idk for sure but my guess it that this reference was created from another scene or something like that

[earnest mantle]

Ah you're right

[lean whale]

I got into some rabbit hole recently where I was purposely trying to use the data from another scene, and it kept resetting. So maybe that asset can be attached to one scene only or something

[earnest mantle]

Just glad that the answer wasn't "Vrchat doesn't support x amount of lights" or something like that haha

[lean whale]

Maybe someone more knowledgeable can chime in. But yea, glad it's workin!

[earnest mantle]

👍

[lean whale]

Hah well that is true for realtime lights- I think the number is 8, but otherwise you can use as many as you can bake

[earnest mantle]

Sweet

[mortal loom]

Hey guys. I'm using "Bakery" is there a reason why my objects are not casting a shadow? I have a directional light in the scene

I have "cast shadows" enabled. I'm using SH lighting

[lean whale]

Do you mean realtime shadow for a non-static sphere?

[mortal loom]

@lean whale yeah

I baked "Full lighting" but I'm thinking maybe I needed to bake indirect or shadowmask?

[lean whale]

I believe that's what shadow mask is for, not totally sure though

But make sure the building material is set to receive shadows and that the light is set to cast shadows too

[mortal loom]

I'll do SH mode with shadowmask. I'll see how that works for low resolution

[lean whale]

The bakery docs have some good info on this- the image on the right here illustrates the difference which I believe is what you're going for https://geom.io/bakery/wiki/index.php?title=Manual#Shadowmask

[mortal loom]

@lean whale thanks for that link. it looks like there might be different versions of bakery going on. I do not have the same options in my bakery light scripts. For instance. I'm looking at "bakery direct light" and there's apparently an option for "baked contribution" and no such option exists for me

so It'll unfortunately remain a mystery for me

That seems to be the biggest issue I have right now. None of my bakery light components have a "contribution" option

but all the manuals suggest that this option exists

yeah still nothing

[lean whale]

Have you changed the render mode to shadowmask in the lighting/bakery menus? Or are you just looking at the light components

[mortal loom]

yep, changed it to shadowmask

[lean whale]

And is the unity light component set to mixed?

[mortal loom]

it was. I changed it to realtime to see if that would make any difference. I couldn't get shadows to show up for either mode

that's 100% of my "direct light" script

missing any options for contribution

[lean whale]

What if you put another sphere between that one and the wall, does it get shadows? Maybe then you can narrow down whether it's the light or the environment

And what does your unity light component look like?

[mortal loom]

like, duplicate the same object? that will not get shadows, since it would be the same object

[lean whale]

Yeah, like see if one sphere will cast shadows on another sphere

[mortal loom]

ohhh I see

I'll try that

[lean whale]

Instead of the building

Cause then you'll at least know if shadows are being cast at all

[mortal loom]

when I prepare the bake, I get a brief instant of this, where it appears like all the shadows are working. very confusing

that only shows up for a few seconds

I am using a special bakery-specific shader that take into account for SH lightmap baking

[lean whale]

Is that what it looks like if you clear all the baked data too? I'm guessing that's just what it looks like with all realtime

[mortal loom]

oh yeah. half the time I get this as an error. I have to spam the "clear bake" a few times over and over and, like a rain dance, it sort of stops happening

[lean whale]

Lol shit

[mortal loom]

it doesn't look that way post-clear

this is how it looks when I clear data

[lean whale]

Are you clearing just the bakery data or clearing it from the unity lighting panel?

[mortal loom]

I do that

[lean whale]

Sorry if I'm not helping much, Idk what the deal is but trying to poke around and see where the prob is coming from

[mortal loom]

nah you're asking good questions that I didn't consider

like I clear the lightmap data from unity itself and all my shadows work again 🤷‍♂️

ok I guess I pasted too quickly damn

[lean whale]

Yeah I think when you do that it makes all the lights go back to realtime

Until they get baked again

[lean whale]

That's before the bake yeah?

[mortal loom]

yeah

still nothing :/ I'm gonna try a few other ideas

changing render mode to "dominant direction"

OK, that didn't work. changing the shaders back to standard

ok. still didn't work. seriously I'm very confused. I've never had this problem before

This must be a critical limitation in Bakery. Maybe Bakery just cannot do realtime shadows. Sure, the manual shows that there's a "contribution" option in the bakery components, but the reality is that that does not exist

[stray bay]

Is it posible to use vertex lighting on my models rather than haveing to bake to a texture?

IIRC vertex lighting is way cheaper (hence why it was done in the PS2 days) and it means I don't need to use 12, 2K textures in order to get a meh quality bake

well I found vertex lit shader, did not expect it to have no shadows but it is there

[lunar narwhal]

setting your light sources to not important sets them as vertex lights

[mortal loom]

I believe you can use light probe proximity (??) volumes wrapped around your object and that'll do a sort of vertex lighting. not sure what the cost of that ends up being though

[stray bay]

how do I modify the importance?

cus RN im useing Mobile/VertexLit
But that has no shadows

a shader that is vertex lit, with a texture, that allows shadows.

perfect for my use case.

at the moment I have a shader that has vertex shadows but is a solid colour or the built in one with no shadows

I may just have no shadows and deal with that.

[patent heath]

Is the object marked as static?

[patent heath]

What do you want specifically?

I mean do you want to bake vertex colors as a lightmap on world objects or to make avatars use only vertex lights
By the way vertex lights can't cast shadows

[stray bay]

My Ideal end goal is to bake lighting to vertex colours rather than a texture, that way I don't need to deal with the pain of haveing so many high res textures that still loose detail.

[patent heath]

aight

well i don't know if you can do that on unity cuz i do my lightmaps on blender
but on blender you can
just put a vertex color slot on the object and on the bake options change the output to vertex colors
also before that the color management has to be on standard

one problem is that i think vertex colors are clamped to 0-1 so it won't work well for intense lights as an exr texture would

[stray bay]

oh I never go over intencity 1 anyways.

so I just need to put my light in in blender and bake there?

[patent heath]

ye

well blender has different baking than unity

blender fully raytraces and stuff

btw idk it it might happen to you but it's possible that the project crashes whenever you bake vertex colors with any device other than the main gpu

[stray bay]

noted, bake with GPU

[patent heath]

ueah that too, but i mean that on user preferences>system blender might creash when baking vertex colors if there's a device other than the main gpu checked, like a secondary gpu or the cpu (for some reason)
but for image texture bakes you can put all the devicces if you want

[mortal loom]

Any idea why I cannot get realtime shadows to work from directional light sources when I use Bakery? Or where I can ask for support on using Bakery?

[patent heath]

you mean after baking?

baking lightmaps converts all the lighting and shadows into exr textures so it cannot be updated realtime
the realtime method uses the light as a camera that renders the depth of every object that casts shadows and then does a fton of stuff to calculate from that texture where should the shadows be present and where not (performance heavy things), all of this for each frame and for each light source with shadows
so i recommend baking it anyways even if it cannot project realtime shadows

[mortal loom]

I'm not sure I understand this response, sorry. I understand how lightmap baking works, and I understand how EXR files work. I make them regularly to bake height maps, and I edit them as environmental light sources. Lightmap baking precomputes the lighting. But we both know this.

In unity's lightmap baker, there is a "mixed" option, whereby some of the lighting is precomputed, and the rest is allowed to continue to exist as realtime shadows. Thus, you are able to explore a world with baked lightmaps, while still having realtime shadows from directional and point light sources.

In Bakery, a third party extension which is usually much better than anything Unity can provide, I am completely unable to get realtime shadows of any sort to work.

[patent heath]

Ah ok didn't take in mind mixed lighting exists, my bad

[ionic kernel]

Any input from you guys?

[vagrant briar]

Just a bakery appreciation post

[tidal spoke]

Unity Left, VRChat Right
Does anyone know why the Post-Processing Bloom effect is showing in Unity but not in-game?

[patent heath]

Do you have a postprocessing layer on the main camera, the main camera assigned to the vrcworld prefab and the postprocessing volume set to a layer other than "all" or "default?

[tidal spoke]

I think indeed it was the cam not being assigned to the vrcworld prefab 👍

[patent heath]

Cool

[modest vapor]

Bloom enjoyer I see

[rancid tulip]

I'm having a brain fart when it comes to light positioning. Is there any way to have a baked light have a "near clip"? The reason being, the mesh of the bulb itself appears to be blocking the light propagation itself.

e.g.

[graceful tartan]

If you seperate the light material part from the lamp post as a hole, you could set it to not cast shadows(while still maintaining shadows from the post) then it won't get in the way of the light.

[graceful jetty]

I've started work on a new world, and for some reason I can't bake a reflection probe without unity trying to bake the lighting in the whole world

The lighting isn't set to be baked anywhere so I don't know why it's trying to

[barren crater]

In the bake button on the lighting tab, there's an arrow on the right side you can click and it'll give you the option to just bake all reflection probes. The same thing applies for each reflection probes' bake button

[manic rampart]

Hi. Are realtime shadows not compatible with quest?

[supple harness]

Realtime light is supported by the quest, but comes with a huge performance hit.

[manic rampart]

yes, but when I have the realtime lights, there are still no realtime shadows

Are the realtime shadows supported by quest?

[supple harness]

I already answered that it supports, you can turn on the shadows. quality settings (> Project Settings... > Quality)

[manic rampart]

you answered regarding realtime lighting, not realtime shadows

and okay! Thank you!

[manic rampart]

hi. So I enabled shadows, but when I uploaded it, it disabled it again. What do I do?

I think it's not saving the changes I made to the graphics setting

how do I get it to save it?

oh silly me! I just use control-S lol

Nevermind. It's still not saving it, even though I used control-S

I think that vr chat overrides our quality settings and sets it to what it originally was for vr chat

Can anyone verify whether this is true?

Because it would be great if I could get these clouds to work on quest

but I think it's not working because the depth buffer isn't working because vr chat automatically disables realtime shadows for quest

[fallow lark]

yeah I think that's the case

[manic rampart]

okay! thank you!

[fallow lark]

so yeah you might have to use a different design for your clouds on Quest

[vagrant briar]

Caught me in 4k

[glad rock]

So Everything in my map was nice and dark and after I baked my lights it came out looking like someone was shining headlights through my window? Any idea why everything is now lit up?

To

It somehow even took out the plants?

[hushed jetty]

Training with Bakery

[glossy meteor]

switch your project to linear mode

[atomic hamlet]

Hey, when baking, the lighting looks good. after the baking ends the lights on different surfaces are pixelated and the world overall is more brighter.

The first image shows the final look after everything is done.
the second image is how I want it to look like. And thats how it look during "finalizing baking".

[atomic hamlet]

my current settings

nvm. I had the build set for android. changed it back to windows and its fixed

[torn rock]

I just bought Bakery Lightmapper cuz I've heard a lot about it being great. But I'm struggling to make a good baked lightmap with it.
Some objects and areas are very dark. They are set to static. They have UV lightmaps enabled.
Third pic is without baked lightmap.
What am i doing wrong?

[lean whale]

Where is the bright light supposed to be coming from? Like do you have light objects in your scene that are supposed to be lighting those walls or is it a lot of skybox/ ambient lighting etc?

[torn rock]

There are some point lights. Some other lights are spot lights. No directional light.

[lunar narwhal]

are you actually using the bakery light components? because it doesn't really look baked to me

[lean whale]

^

And it's supposed to look like 3rd pic?

Or that's close to what it looks like in full realtime?

[torn rock]

Yes.. maybe. I’m not sure. This is my first time with Bakery.

[torn rock]

Yes

[lunar narwhal]

bakery bakes with bakery light components, and doesn't use the unity lights at all. You can keep them in your scene as a reference, but you should leave them disabled

its also not entirely a 1 to 1 match so you'll have to play around with the settings to get it to look the way you want

I'd give the manual a read https://geom.io/bakery/wiki/index.php?title=Manual#Quickstart

[torn rock]

Ooooh

So, I replace the Unity lights with the ones from Bakery?

[lunar narwhal]

yeah

[torn rock]

Huh interesting

[lunar narwhal]

if you place the bakery light component on the same object as your unity light, bakery has a button to match settings

but you should always leave unity lights disabled as they will just act as real time

[torn rock]

So, basically, I remove the Unity lights. Put the Bakery lights in their places?

[lunar narwhal]

basically

[torn rock]

Oh I see. Weird but thank you for your help.

[lean whale]

You shouldn't need to remove or disable the unity ones. I just add a bakery component to mine (which also has a nifty button to match it's settings to the unity light)

And I like the convenience of being able to clear baked data and quickly look at the scene with realtime light

[torn rock]

Ah ok. Thank you

[hushed jetty]

Another map with Bakery

[earnest mantle]

Does bakery produce better lighting or is it just faster than any of the built in lightmappers? I've heard a lot of conflicting stuff online

[hushed jetty]

Both. much better quality with great precision and use the RTX ability of you're gpu to product them and baked them. here it's some tests i have made at a map with basic geometric form to learn it

[earnest mantle]

Oh wow, cheers for the examples. Was hoping for a better alternative to the default one which usually comes down to spending ages tweaking settings for a semi-decent outcome that isn't blotchy.

[hushed jetty]

for the confict yes i don't know yet how to made a classic mixed directional lights and have the rest of the lights with bakery. but yes bakery is pretty simple to use very optimise and very powerful

here it's a prefab map include with bakery and when all lights is baked the result is impressive in rtx mode and the denoiser optix 7

[earnest mantle]

Wow, getting close to unreal engine level of baked lighting

[hushed jetty]

unity is the best rival of unreal 4. and that little map asset include with bakery is perfect to training and test. PS: the shader Filament Master by Silent is perfect with bakery

And unity is prepare itself to face unreal 5 https://www.youtube.com/watch?v=Ri8U2COIPTQ
After lets see for optimisation

and yes the women is a 3D model here

[earnest mantle]

Oh damn

[simple sinew]

Anyone know what could be causing these weird lighting issues? It's not emission or GI static

[earnest mantle]

Do they have lightmaps?

[simple sinew]

No, but I somehow managed to make half of them cooperate

[hushed jetty]

did you doing that ?

[simple sinew]

Yup, has nothing to do with the static

[hushed jetty]

hmmm maybe the shader on them try that one it's filament master by silent https://drive.google.com/drive/folders/1isI39rcKnGX5LZgDqK6jaPZDw1AoNvBg?usp=sharing

you just have to put the folder at you're unity project

[simple sinew]

Aight cool, I'll check it out when I get home

[dire crater]

What's up with my baked lighting looking so strange

Everything else is fine, except for these trees

[earnest mantle]

I had something very similar and it was caused by overlapping uvs

[dire crater]

This happens all the time for me. I usually end up using realtime lights for the broken objects

[torn rock]

Ok, so the lighting is much better and just looks like what I wanted after baking with Bakery. However, I noticed that the world's download size has increased by 12 MB. How do I compress the lightmap if there's no option on the setting?

never mind. figured it out

[torn rock]

wait, it didn't work. Ok, how do you reduce the size of the lightmap?

[earnest pagoda]

Reduce the value

20 is big, 12 is smaller.

And less textures if possible.

[torn rock]

Ok

[earnest pagoda]

in bakery advanced, use bigger textures. minmal 512

simple will use even small 16x16 which can makes many textures

[torn rock]

i see

[lean whale]

You can also select the actual lightmap file(s) that gets produced and change its import settings. If you're concerned about download size I would set it to use crunch compression, and if the size is still not small enough then you can also lower the res there in the import settings

[torn rock]

ok. I'm curious. What about Gi VRAM optimization?

[torn rock]

also, you meant like texels?

[lean whale]

I think that just affects the way your pc handles the baking process, not the lightmap that it produces or runtime performance

[torn rock]

ah ok

ok, got it. thank you

[earnest pagoda]

How can i bake lighting with LOD objects? What is best way to deal with it?

[latent latch]

How do I toggle the skybox material?

Like if I want a button on the map that toggles the Skybox Material to something different

[glad rock]

So if I’m making a club and want flashing lights, can baked lights be programmed to turn on and off or would not be possible

[earnest mantle]

Nah, baked is a texture applied over an object, so you'd have to bake the lighting every frame if you wanted that.

Which would probably give you 0.000005fps at best

[glad rock]

Lol thanks

👍🏻

[fallow lark]

https://github.com/AcChosen/VR-Stage-Lighting

[rancid tulip]

Does anyone know why objects, when set to 0 size in the lightmap, still appear to stay mapped in the lightmap, even after rebaking, with garbage being applied as their lightmap?

It explicitly states that this shouldn't happen, just that they will contribute light, but not be mapped.

[lean whale]

Hm that is odd. Did you clear the baked data before rebaking? If you're using bakery did you clear the data through the Bakery menu and not the Unity menu?

[rancid tulip]

No. Because I'm baking like a dozen different zones so I don't want to clear all baked data as that would wipe all the Bakery sectors, not just this one.

[lean whale]

Ah, well what if you at least delete the lightmap that it is associated with and then rebake? Does it just generate the same one again?

I don't know much about using sectors either, I wonder if it's a limitation of that specific component of bakery or the way you have that set up
