kinda 😄

#

well, what i want to point out is, that there is a _ZBufferParams

#

this is the explaination for my initial problem about the LinearEyeDepth havon more than one parameter

#

i just need to find out what the zbuffer is and then i might have the hdrp piece for builtin LinearEyeDepth

thanks alot for bringin me this far

#

testing BOTD on 2018.2 atm

#

kinda sucks that GPU lightmapper is still unusable on that, trying to rebake lighting on cpu progressive is taking forever even on high end rig

#

also barely getting proper cpu utilization on this

#

it's jumping between 20 and 50% most of the time

#

#

I guess 1 hour doesn't sound all that bad if you don't know the speed on gpu bakers 🙂

#

mainly just annoyed that this doesn't utilize all cores properly to the max

glad tartan Apr 6, 2020, 1:20 AM

#

I was just thinking about something that raised this question. From the Roadmap Q&A someone asked when Built-in would be deprecated and a dev replied that it's not anytime soon as it will be getting new platform support (the new consoles). Since the Xbox Series X will be using DX12 U which supports VRR, Mesh Shaders, Ray Tracing, and Sampler Feedback.

Will the Built-in pipeline just support DX12 U (just the updated API) or maybe not at all and still use DX12 and get build support and nothing new for the new consoles? Basically helping devs who wanted to target those platforms with their current projects who can then transition to HDRP after?

turbid matrix Apr 6, 2020, 10:41 AM

#

@glad tartan isn't DX12U just extension set for DX12? meaning they can probably use core DX12 on next gen consoles even before those additinal feats get implemented (if they even get implemented)

#

I can totally see VRS and DXR 1.1 getting supported but I wouldn't count on getting the rest supported by unity any time soon

#

I'm talking about SRPs now

#

I wouldn't expect any of the DX12U specific feats on built-in renderer

turbid matrix Apr 6, 2020, 11:24 AM

#

note to self: don't try to put 16k resolution planar reflection on HDRP

#

unity not only crashed but my whole windows stopped responding, everything just froze 😄

SRP Repository Migration

THIS REPOSITORY HAS MOVED
tl;dr As of April 6 2020 the old SRP repository is no longer in use or maintained. Please migrate to using the new...

#

@turbid matrix Purging old branches will happen over the next few days.

turbid matrix Apr 6, 2020, 12:43 PM

#

ah ok, that makes more sense

#

there's close to 800 branches there now which all just can't be relevant anymore 😄

remote forge Apr 6, 2020, 12:44 PM

#

Yes, it increases the clone time a lot from our tests. We think we can prune abut 75% of them.

#

(keep internal backup of course :))

turbid matrix Apr 6, 2020, 12:44 PM

#

the folder structure is still the same, right?

remote forge Apr 6, 2020, 12:44 PM

#

Yes, all the same there.

turbid matrix Apr 6, 2020, 12:44 PM

#

like, if I just move my upstream remote from my SRP fork, it should just work

remote forge Apr 6, 2020, 12:45 PM

#

Oh. That's specifically called out. We transitioned to LFS which means we the SHA's are all changed.

#

So you will need to reclone 😦

turbid matrix Apr 6, 2020, 12:45 PM

#

ah, that's good to know

#

well, I'll see what I can work out

#

I have a lot of custom branches on my own fork

#

so can't just naively reclone

remote forge Apr 6, 2020, 12:46 PM

#

Do you have local modifications? Are they on a custom branch? I can walk you though migration.

turbid matrix Apr 6, 2020, 12:46 PM

#

there is mention on this on the FAQ tho

#

It will be difficult to migrate and also preserve history, you will need to either cherry pick your individual commits across to the new repository or do diff and make a single commit with this diff

#

We do this by taking a diff from the last master you had, and diff the working branch. Then apply this to the new fork.

#

yeah, it's not impossible, I can make branches again just fine

remote forge Apr 6, 2020, 12:47 PM

#

Yeah. So in your case depending on if you have been merging into your custom branches or rebasing then there might be different approaches.

turbid matrix Apr 6, 2020, 12:47 PM

#

I'm quite used to git, just trying to figure out the best route of action

remote forge Apr 6, 2020, 12:47 PM

#

👍

turbid matrix Apr 6, 2020, 12:49 PM

#

I guess easiest would just to squash the changes on my custom branches and cherry pick them to the new repos branches

remote forge Apr 6, 2020, 12:50 PM

#

Yeah. Make a clone of the new repo, set the old fork as a remote then cherry pick the squashed change

turbid matrix Apr 6, 2020, 12:54 PM

#

I'm now officially the first person to fork the new repo!

turbid matrix Apr 6, 2020, 12:58 PM

that being said, I should have just waited for you guys to clean it up first 🤔

remote forge Apr 6, 2020, 12:58 PM

#

Your choice, it will be within 7 days I think .

turbid matrix Apr 6, 2020, 12:59 PM

#

it's not really an issue, can just let git clean it after it's done

#

I wipe all the branches from the fork itself anyways as first step

#

always just pull things from upstream (unity) repo as basis

#

my public SRP repo fork only has like 6 branches

#

and have like dozen local ones

remote forge Apr 6, 2020, 1:01 PM

#

smart 🙂

turbid matrix Apr 6, 2020, 1:01 PM

#

it's impossible to find the branches if those 800 are there

lyric ravine Apr 6, 2020, 1:57 PM

#

@remote forge User 1 here (2nd fork). I find it a bit weird that you have already made the SRP repo private, as that means that all the information around mitigation is in the NEW repo, not the old one

turbid matrix Apr 6, 2020, 1:58 PM

#

it's just temporary

#

like the forum post said, they'll take the original repo offline for few days so they can backup it properly

remote forge Apr 6, 2020, 1:58 PM

#

@lyric ravine We are backing up the repository right now.

lyric ravine Apr 6, 2020, 1:58 PM

#

Make it readonly, clone it, whatever, but you ARE disrupting our active projects by that as it's not possible to continue with planned work (merging SRP branches into our fork)

#

If you plan sth like this don't announce it like 2 hours before you do that

remote forge Apr 6, 2020, 1:59 PM

#

If you have a fork though you have the code?

turbid matrix Apr 6, 2020, 1:59 PM

#

all branches are on the new repo tho?

lyric ravine Apr 6, 2020, 1:59 PM

#

Yes but there was planned work of merging in stuff from master.

#

@turbid matrix the remotes are not compatible as the description says. Can't just merge over, will have to now do totally unplanned rebase/patch/cherry-pick work

turbid matrix Apr 6, 2020, 2:00 PM

#

yeah, it's going to be a bit of pain during the transition

lyric ravine Apr 6, 2020, 2:00 PM

#

That's fine, but man give us more than an hour of notice

turbid matrix Apr 6, 2020, 2:00 PM

#

but SRP repo is not getting any updates anymore, so you have to move to new one at some point anyway

#

ah, thats a fair point

lyric ravine Apr 6, 2020, 2:01 PM

#

to at least do a pull of all existing stuff

turbid matrix Apr 6, 2020, 2:01 PM

#

I keep my upstream fetched most of the time so I have local version of all of the SRP repo

lyric ravine Apr 6, 2020, 2:02 PM

#

Well some of us have to work from home and do child care and can't just jump in an hour to do that after the weekend

#

So, @turbid matrix your "old" fork should be up-to-date with latest Unity version that was available?

remote forge Apr 6, 2020, 2:03 PM

#

Sent you a direct message herbst

turbid matrix Apr 6, 2020, 2:03 PM

#

my public fork has none of the unity's branches, but the local forks remote for Unity's repo (upstream) has all the things they've had in past

#

if you have a clone from original SRP repo, you can just add it as local remote for your new fork

#

I'm currently transitioning my custom branches to the new one, can report if I find any showstoppers

turbid matrix Apr 6, 2020, 2:59 PM

#

didn't really face any major issues since I don't need to rebase anything, basically commit hashes are different but I mainly had to cherry-pick commits so that was all nice and simple

#

how I did it on my end was that I just used git checkout for the base using new repo's commit hash values to get the branch to same starting point or if it was based on actual release, just checkout the release from new repo as basis then just cherrypicked all custom commits from the old fork on top

#

since all the same branches are on new repo (as on the old one), merging work from there should work just like before if you just redo your local branches first to be based on the new repo

#

btw, it's crazy that we were at 1.x on SRPs just two years ago (cleaning up my forks releases now)

#

been testing these ever since they got here and it feels like way longer time already

remote forge Apr 6, 2020, 3:12 PM

#

The version numbers can get a little crazy if you try to do semvar properly. We are only 'mostly' correct and it's still a lot of numbers.

turbid matrix Apr 6, 2020, 3:14 PM

#

yeah, I guess that slows down a bit now that the amount of tech releases got dropped by one

severe spear Apr 6, 2020, 5:25 PM

#

Anyone able to comment on what the overhead is like for the decals in HDRP? I'm assuming they are batchable when set to static and what not eh?

turbid matrix Apr 6, 2020, 5:26 PM

#

I'd just test them on your setup and make your own conclusions

#

it's hard get generic impressions on a thing like that when people's use cases for decals can vary a ton from small bullet holes to actually dressing half the level

hazy yoke Apr 6, 2020, 8:34 PM

#

if I recall so long as they arent set to affect transparency they should be fine to use, we used them as mesh decals on most of our geo as detailing

strange sequoia Apr 6, 2020, 9:50 PM

#

So I'm wondering how srp handles compared to standard where objects, textures and materials are concerned.

I know with standard you want to minimize the number of materials and textures, using larger bundled textures if needed.

From what I hear unreal engine is not like this and handles more materials and more smaller textures better. Like having many objects with tiled textures.

So has SRP changed this from standard or still roughly the same performance and draw call wise?

turbid matrix Apr 6, 2020, 9:52 PM

#

@remote forge fyi, there's a typo on line 48 here: https://github.com/Unity-Technologies/Graphics/commit/653bb2d619b5f6bcea38949721b600be84106d73 "Unity Grpahics repository"

turbid matrix Apr 6, 2020, 10:49 PM

#

@strange sequoia SRPs can use SRP Batcher that can batch materials that use the same shader variant

#

more technical explanation here: https://docs.unity3d.com/Manual/SRPBatcher.html

strange sequoia Apr 6, 2020, 11:12 PM

#

Ah neat, thanks

turbid matrix Apr 6, 2020, 11:13 PM

#

well, "can" use is bit wrong way to say it. it's enabled by default

strange sequoia Apr 6, 2020, 11:21 PM

#

Hm, maybe i will change to URP....

#

I'm rather late in the game for my visual development, but i should at least research it in the mean time...

#

The issues with the number of materials is my biggest problem especially when i target web and mobile platforms beside PC...

#

And i recently decided to scale back other aspects and push for quality. So this might be a reasonable part of that compromise.

strange sequoia Apr 7, 2020, 1:20 AM

#

Another question, normally i use shadow mask for my baked shadows and not supporting that kinda sucks.

And it seems like there's some AO options.

So really i'm down to that one thing. I'm pretty sure baked indirect doesn't solve this well enough.

#

Considering most of my game takes place insider a building baked shadows worked best, but without shadow mask it might consistently look awkward...

I dunno maybe i'll have to test it...

turbid matrix Apr 7, 2020, 5:35 AM

#

@strange sequoia ?

#

afaik shadow mask is supported by HDRP

#

according to docs it's per light setting there

strange sequoia Apr 7, 2020, 6:35 AM

#

No I need URP due to android and webgl support

turbid matrix Apr 7, 2020, 6:39 AM

#

ah yeah that's more limited then

#

hmmmm, this says it's released: https://portal.productboard.com/8ufdwj59ehtmsvxenjumxo82/c/21-shadow-mask-support

Shadow mask support - Unity Graphics

A shadow mask is a Texture that shares the same UV layout and resolution with its corresponding lightmap. It stores occlusion information for up to 4 lights per texel, because Textures are limited to up to 4 channels on current GPUs.

actual docs state it's in research

#

Yeah fair enough. Very time I consider it theres always a feature missing to make me hold off XD

turbid matrix Apr 7, 2020, 6:48 AM

#

URP has been like that, yeah

#

deferred, ssao, point light shadows still coming up

#

from those deferred and ssao have had wip branches for quite a while

remote forge Apr 7, 2020, 7:27 AM

#

URP has been beefed up in terms of people over the past few months so start expecting more things to land 🙂

#

SSAO and Deferred are trucking along well and we are really starting to round out a lot of the other features 🙂

#

Also so many bug fixes and minor improvements.

#

But yes, some things some people still need are not quite there yet, but we are working on them.

elder merlin Apr 7, 2020, 7:45 AM

Hey, I upgraded to 2019.3.8f1 yesterday from 7f1, it said it had to update HDRP materials, and now it's throwing me GetLoadedImportedAssetsAndTargetHashes called with invalid targetHash with soem assertion, but no file or path info. Anyone experinenced the same?

On 2019.3.8f1 update broke URP shaders and killed previous package when switching to another version. After installing URP again, just opening them up in Shader Graph and re-saving fixed them.

strange sequoia Apr 7, 2020, 10:54 AM

#

Well thats good. Cause HDRP looks nice but i can't use it at all far too limited platform wise. :<

So i really need URP feature complete.

turbid matrix Apr 7, 2020, 12:44 PM

#

hmmm, not sure what to make out of this comment:

📎 unknown.png

#

I'm mainly puzzled that he mentioned angle based fading, I didn't know that was on the table

#

I'm aware of the decal layers branch though

scarlet hull Apr 7, 2020, 1:33 PM

#

Why puzzled ?

turbid matrix Apr 7, 2020, 1:34 PM

#

based on the earlier discussions, it seemed like it wouldn't happen due to no normal data at the decals execution point

#

I'm mainly curious if this is now happening still or if that comment was only for the decal layers essentially (which I know has been worked on already)

#

I asked about it on the thread as well (https://forum.unity.com/threads/hdrp-decals-projection.861790/#post-5680951)

#

as a side note, would love to have some product board for HDRP as well (like there's now for URP and SG)

#

would be so much nicer to track what's planned and what's possibly coming

#

having github access is already awesome for seeing the wip things though 🙂

scarlet hull Apr 7, 2020, 1:50 PM

#

It is happening. iirc, the angle base fade is done using a normal approximation of the depth map

turbid matrix Apr 7, 2020, 1:50 PM

#

that's nice 🙂

#

and yeah, I think we discussed the normal generation here too last time this topic was up

#

main concern there is the cost

shell vigil Apr 7, 2020, 2:07 PM

@long wagon So I should remove package and add again? I don't have any custom shaders.

I only get them on project load

I dunno if it's even related to HDRP in any way, could just be the new asset db

I haven't really seen any negative impact despite getting those errors so I've just ignored them

Guys i want to make a mobile game and use URP the problem is that as soon as i use teh URP in my project i start seeing some lag like some frames etc i dont know what's teh problem but the projects runs smoothly without using it (the project is 1 sprite and 1 controll script so tehre si no performance issues or whatever)

#

if anyone knows what's this im really stuck

rich spade Apr 7, 2020, 5:31 PM

#

@void musk is this in editor or on test device? I would make some basic features then check and compare on test device. ;)
Lag in edit can be anything or nothing, it's what happens on consumer device which matters.

void musk Apr 7, 2020, 5:31 PM

#

in the editor its smooth

#

on teh etst device it fels like there is some lag or some frame problems

rich spade Apr 7, 2020, 5:34 PM

#

then you may be better not using URP, it's still very new and constantly changing. I moved to URP myself recently (desktop target) I notice nothing major. Improvement if anything, mobile platforms vary so much I'd probably not go with URP. But that' sjust my opinion. Others may know better 😉

midnight skiff Apr 7, 2020, 8:24 PM

Hey guys. Quick question about custom post processing shaders in HDRP.
Is a Properties{} section in the shader file the correct way to get these properties in the inspector? Or do i do that within the CustomPostProcessVolumeComponent?

i tried the property field in the .shader but the properties act strange or not at all even though they appear normally in the material inspector.

#

especially interested in a colorpicker. I found the FloatParameter for the CustomPostProcessVolumeComponent but something like ColorParameter does not seem to work

hazy yoke Apr 7, 2020, 8:30 PM

#

Usually if youre doing a post process in HDRP you want to do it through the postprocessingstack (at least if you want to get the blending between volumes and ui)
Otherwise youll probably have to make your own custom inspector

#

Doing it yourself will probably be easier though since I dont think custom post process effects are supported out of the box like they used to be in HDRP, so might need to add in your own delegate callbacks in the SRP

turbid matrix Apr 7, 2020, 8:34 PM

#

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@8.0/manual/Custom-Post-Process.html has example of exposing the properties

#

also the colorblind filter I linked earlier implements enum properties for the custom PP (you need a bit of extra for it)

hazy yoke Apr 7, 2020, 8:35 PM

#

oh awesome, glad to see thats supported again

midnight skiff Apr 7, 2020, 8:42 PM

#

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@8.0/manual/Custom-Post-Process.html has example of exposing the properties
@turbid matrix yeah, i based my current custom PP effect on this, but i couldn't find the right keyword for a colorpicker.
the solution was to just cast.

m_Material.SetColor("_ShaderColor", (Color)PPolor);

#

Though, i still dont know why the poperties in the shader are displayed correctly in the material inspector but dont seem to work

turbid matrix Apr 7, 2020, 8:45 PM

#

again, the HDRP's own PP shaders are awesome resource as they probably implement everything somewhere that you may need

#

that's how I figured how to expose those enums as custom PP properties

#

it's completely undocumented

midnight skiff Apr 7, 2020, 8:49 PM

#

i had a look earlier at the vignette PP because it was the only PP with a colorpicker in the inspector, but that .cs was completely different to the GrayScale custom PP sample

turbid matrix Apr 7, 2020, 8:49 PM

#

if the controls don't do anything, then you don't set them for the shader properly (or to right shader)

#

that custom PP doc did have functional example for that tho

midnight skiff Apr 7, 2020, 9:00 PM

#

setting the parameter from the .cs works now.

but the different method, to set the parameters in the .shader was confusing me because the parameters were displayed in the inspector correctly. I expected them not to show if it was not the correct way for PP parameters.
But after some testing it seems like they are not getting updated by the inspector and only accept the initial value set in the .shader parameters.

#

i wanted to set them from the .shader since i know it that way. but i will just to it from the .cs now.

^ been curious to see the current snapshot of HDRP + raytracing.

I've gone through the wizard and changed it all over to the necessary config.

Whenever I change any of the render pass for materials to Raytracing I get nothing out of like the cube in the image above.

And yes, I am running on an RTX 2080 😛

#

Has anyone ever dealt with this, and what I may need to do to correct this?

glad tartan Apr 8, 2020, 12:55 AM

@severe spear The only material type that needs to use the raytracing render pass is transparency and you use a Recursive Rendering volume component to make it render the glass. Everything else uses the default render pass

One thing I'd suggest is to check your settings to see if Raytracing is enabled in the frame settings. it might be enabled on the Pipeline asset but not in the frame settings

Hey, I have a little problem.. I am using the HDRP.
I have a point light set on a wall and it shines on the other side of the wall. It bakes on the other side too. If I decrease the range then the light is too small and I can see like no light. What should I do to make the light not to through the walls?

scarlet hull Apr 8, 2020, 7:59 AM

#

@worldly sedge You enabled shadows for this light, right ?

turbid matrix Apr 8, 2020, 8:35 AM

#

@severe spear make sure your materials have higher smoothness than that 0.9 or lower the threshold on ssr settings

#

Default 0.9 is too high value IMO

#

Altho lower smoothness values require agressive denoiser values to filter the noise they generate on RT reflections

guys do you know why it is taking so long to hdrp 7.3.1 become verified? there is no verified package greater than 7.1.8 and in my opinion 7.2.0 was pretty big

turbid matrix Apr 8, 2020, 9:18 AM

#

it's bit weird yeah considering HDRP is officially released on 7.2.x

#

I'm guessing they did the verification passes for packages before 2019.3.0 released officially and they don't normally do them again for the same major version or something

turbid matrix Apr 8, 2020, 9:43 AM

hmmm, you need camera stacking on 2D as well? https://github.com/Unity-Technologies/Graphics/tree/2d/camera-stacking

I can imagine there being some use cases if URP's 2D lights don't have light layers but would think it would be better to just implement them instead then

@gilded maple "downgrade from HDRP to SRP" doesn't make any sense

gilded maple Apr 8, 2020, 12:22 PM

I don't have choice because I really need volumetric clouds for my project and I didn't found any assets that support HDRP or URP

scarlet hull Apr 8, 2020, 12:23 PM

Oh, so, I guess you're using wrong name here. Are you refering to the "legacy renderer" ?

gilded maple Apr 8, 2020, 12:23 PM

#

yes

#

What is the difference ?

scarlet hull Apr 8, 2020, 12:24 PM

#

SRP is the general API to write your own renderer in Unity, it's the fundamental brick that is used to build HDRP and URP

gilded maple Apr 8, 2020, 12:24 PM

#

oh

#

Ok

scarlet hull Apr 8, 2020, 12:25 PM

#

Build-in (sorry, I should not name it legacy) renderer is the "old" blackboxed renderer of unity

#

And no, there is no automated way to convert from HDRP to built-in, but it's possible to automate it yourself, or maybe somebody already did it and posted the needed scripts

gilded maple Apr 8, 2020, 12:26 PM

i have to build a tablet app.. i usually use 2018 is there a big reason why i should move to unity 2019 for this or should i just stick with 2018. Is URP our of preview and does it make a big difference on 3d app performance on tablets or is it the same as the unity rendering in 2018

gilded maple Apr 8, 2020, 3:15 PM

Yes URP is now out of preview, and you have more options for render pipeline.

simple vine Apr 8, 2020, 6:15 PM

#

Hmmmm, I quite confused

#

I'm writing a simple compute shader from scratch and it doesn't seem to work

#

The whole thing that the compute shader does is that it writes 1 to the UAV texture (RW_TEXTURE2D macro unrolls in Texture2D<uint>)

📎 unknown.png

#

The texture is properly marked as a UAV one, I get a proper amount of thread groups

📎 unknown.png

#

But the output is always zero, as if the shader is never ran

What might be the problem? It's a very simple thing for it to break, the error must be a very stupid one that I can't spot

split spire Apr 8, 2020, 6:41 PM

Don't you need to run the program? Like dispatch the compute shader from script and hit play?

scarlet hull Apr 9, 2020, 3:29 PM

So, might as well be expected 🤔

hazy yoke Apr 9, 2020, 3:29 PM

#

yeah, thats likely just due to how shadows work with point-lights though (6 shadow maps) so youre just not hitting the boundary

#

the more you pull it up I mean

it does look like that blend is odd

just out of curiosity, why not add support for dual paraboloid projection for point light?

late schooner Apr 9, 2020, 4:06 PM

#

would suggest octahedral projections over dual paraboloids

#

but shadows in general are not in a great place w/ Unity 😐

indigo summit Apr 9, 2020, 4:17 PM

#

it's under the shadow of other issue . . . . 😬

late schooner Apr 9, 2020, 4:19 PM

#

yeah unfortunately I think there are a few pretty fundamental design mistakes with SRP right now-- I don't so much mind that the stock shadow solution has edge cases

#

what I do think was a huge, huge problem is the lack of a modular shadow system to begin with

#

since it results in duplicate work for Unity nor can users implement their own workaround(s) or make stylistic decisions

#

I'm actually a little puzzled why product management didn't think to do this to begin with considering HDRP essentially wrote one anyway

indigo summit Apr 9, 2020, 4:21 PM

#

you mean the legacy renderer shadow system?

late schooner Apr 9, 2020, 4:22 PM

#

not exactly

#

so right now HDRP has a whole internal system dedicated to managing/caching shadow maps for lighting

#

Unity Engineering has a whole matrix of rendering algorithms and quality settings set up

#

as has been observed, the URP team has access to none of this despite it actually all being equally valid for forward rendering systems, etc.

#

you can build invalidation algorithms to re-use the same shadow map for every light if you feel like it

#

so what's baffling is that rather than share work across teams it looks like UT PMs just forced everyone into doing stuff from scratch with the net result that there are two monolithic systems with independent/conflicting settings

#

especially since one of the stated goals of SRP was modularity in rendering

#

I think this was a really bad judgement call

indigo summit Apr 9, 2020, 4:26 PM

#

ah, i see what you mean

late schooner Apr 9, 2020, 4:27 PM

#

postprocessing is another example of the same kind of mismanagement

#

that's a straight regression at this point

#

with the separation of the single PPv2 into per-project stuff

#

why can't URP use the HDRP SSAO framework?

#

Additionally, the label in my Unity editor says "Render Mode" instead of "Render Type". Does anyone have experience with camera stacking in 2019.3?

that you move along camera etc

turbid matrix Apr 10, 2020, 5:16 PM

#

@glad tartan can you be more specific?

#

HDRP wizard already places new scene default for you

#

there's a default resources folder in the assets folder that has prefab for the new scene

#

if you use dxr it has it's own prefab as well

#

you can also set default volume profile that applies to all your scenes

glad tartan Apr 10, 2020, 5:35 PM

#

Yea, I know about all that. I've been following HDRP closely, and using it exclusively since it was available in 2018.1 and messed with it when you could only get it from GitHub and it came bundled with LWRP and all the demo scenes.

What I'm talking about is specific, basically exactly what I mentioned. There is a package in Unity called Scene Template It's not well know or advertised by Unity so I guess it slipped by a lot of people. It allows you to create custom scene templates for your project and be able to choose which one to create a new scene from. I've been using it since it was added to the package manager. After a while I saw there was a branch in the SRP repo that was going to use this instead of the prefab asset the wizard creates and it would be bundled in the project templates. So I was wondering if that is still in the works or it got scrapped.

Hi

#

Is it possible to render a camera to an external texture2d with rendertarget flag using DirectX11 ? I don't care about C# or C++ API

dawn sorrel Apr 11, 2020, 9:52 AM

#

I've been doing some stuff in Unity before but I would like to begin anew
I'm not sure which rendering pipeline I would like to use (and also which version of Unity)
My requirements and other stuff:
-being able to use materials with ao / metallic / roughness (or smoothness) textures
-being able to use decals
-vfx graph and preferrably unity'sparticle system at the same time
-I don't care about 2d / dots
-It can't be a pipeline that needs a really good PC to work fairly well, my good old wooden PC won't handle it

#

Any tips / advices?

drifting vault Apr 11, 2020, 10:23 AM

#

@dawn sorrel use URP (Universal Render Pipeline)

#

that pipeline focused on mobile/potato PC/portable VR

dawn sorrel Apr 11, 2020, 10:24 AM

#

Last time I used it there were no decal shaders available

#

Has it changed?

drifting vault Apr 11, 2020, 10:24 AM

#

URP do not have build-in decal system

#

but you can buy decal solution for URP in asset store

#

or make own

dawn sorrel Apr 11, 2020, 10:25 AM

Okay, thanks for help

#

You're asking a pretty specific, technical question and missing some important semantics, calm down ^

#

answer depends on if you need Unity to draw to a surface you created or if you need to access a native ID3D11Texture in your code

#

see Texture.GetNativeTexturePtr if the latter

barren marsh Apr 11, 2020, 1:11 PM

#

@late schooner I have it man , I'm not angry or something :D

#

I'm using SharpDX

Original Question :
https://gamedev.stackexchange.com/questions/181601/optimized-way-to-show-unity-rendertexture-in-wpf-using-sharpdx

UPDATE 1 :
Ok I got it working but in non-standard way , I need better and faster solution to this and my sharing surface code is not working...

This is the method I used Memory Streaming and it works fine but it has no good performance for large results.

and this is my method using DirectX surface sharing which result a black output with no errors.

Optimized way to show Unity RenderTexture in WPF using SharpDX

I'm writing a Unity plugin which uses WPF for UI , Plugin runs in same process of Unity and has direct access to unity's memory.

Unity Code :

But Now I'm thinking if it be possible to just render unity camera to a shared Texture2D generated by SharpDX directly.

late schooner Apr 11, 2020, 1:17 PM

and that part, unfortunately, is harder, as I don't believe there's a way to have Unity consume a native IntPtr D3D resource

@late schooner Even within C++ native plugin ?

late schooner Apr 11, 2020, 1:18 PM

#

I think the native plugins assume you're doing all the work with native code, I don't think you have much of the C# binding back-end

#

you can absolutely query the device/resources/etc. and issue commands, but I don't think there's a layer to actually create new C# objects

barren marsh Apr 11, 2020, 1:20 PM

#

I don't have any issue I do C++ and C# , If it's possible I'll do it but I don't want to waste my time on something is not possible

late schooner Apr 11, 2020, 1:21 PM

#

I understand, I'm simply saying that I don't believe the internals of the C# binding layer are exposed to the Unity native plugin API

#

on the basis that Unity Engineering thinks you would do C# things in C# and C++ things with the extension points made available

#

I am doing some poking around in the official samples

barren marsh Apr 11, 2020, 1:31 PM

#

Cool , is there any place I be able to get help and information from unity official engineers ?

#

Because It seems discord level is not suitable for advanced (not exposed ) subjects like this

turbid matrix Apr 11, 2020, 1:37 PM

#

it's not that advanced topics wouldn't fit here, you are just asking about super niche thing

@turbid matrix thanks , I checked this before , it's nothing different than SharpDX by hack into unity graphic device , the point here is** I don't want to get a pointer to a unity texture and do stuff I want to set a pointer**

late schooner Apr 11, 2020, 1:44 PM

#

and to reiterate to you

answer depends on if you need Unity to draw to a surface you created or if you need to access a native ID3D11Texture in your code

I understand, I'm simply saying that I don't believe the internals of the C# binding layer are exposed to the Unity native plugin API

#

in order for native-side texture creation to work, you need to make the C# binding aware of a lot of technical specifics for platform 3D APIs

#

and this problem goes away if you adopt a black-box/one-way binding approach

barren marsh Apr 11, 2020, 1:46 PM

#

@late schooner I don't need to use any C# I can do native

#

so , Unity 's RenderTexture is a DX11Texture2D with RenderTarget flag ?

late schooner Apr 11, 2020, 1:47 PM

#

We are aware that RenderTexture exists as a C# class in the Unity script layer

#

?

#

not necessarily, at least in terms of formal guarantees. Something like that is involved, but there are a few other D3D resources in there for MSAA resolution, etc.

glad tartan Apr 11, 2020, 4:20 PM

#

So I tested the Probes volume and it seems that it's just a light probe grid that stores better lighting information. So you still have to bake your lightmaps and then it also store that lighting information in a probe volume asset for dynamic object to use.

I thought it would have been able to be baked without having to bake lightmaps as well

#

It works solid though, the dynamic objects looked like they were also baked as well. Even if you cleared your lightmaps but not the probe volume bake and you enable the probe volume, it looks exactly like the baked lightmaps.

#

Guess now I wait for DDGI or the realtime solution mentioned to be coming next year. Then I wont have to worry about baking lightmaps and also be able to get decent occlusion for things like vegetation.

barren marsh Apr 11, 2020, 4:56 PM

@late schooner I thought Unity has C++ api too , but it doesn't it seems :) Now I get what you say

upbeat badger Apr 11, 2020, 5:11 PM

#

You dont need to bake lightmaps for probe volume. Enable contribute GI static flag then set receive GI type to Light Probes in Mesh Renderer and bake Probe volume.

#

This is my test scene for probe volume without lightmaps

Cube inside house is dynamic everything other is static

late schooner Apr 11, 2020, 5:19 PM

I'm trying to create a basic lamp for my game. I added this light property to the prefab, but there is no light emitted from my lamp, either in the scene view or in-game. Is this due to something I'm overlooking in the Universal Render Pipeline? Online tutorials that I have watched never had this problem.

@glad tartan Thats what im waiting for too, but i rencently tried the ray tracing solution and i must say it was amazing im gonna have to get an rtx to render my scenes properly

glad tartan Apr 12, 2020, 4:50 AM

#

Yea, raytracing is pretty sweet. I use it every now and then when there's a new feature added or if I want to take screenshots since it runs at 1-5 fps with all effects on using a GTX 1080 GPU. I'll be using it a lot more when I get a GPU made to do Realtime Raytracing. It will be nice when that's the standard.

you'll get used to these settings getting scattered around but it's not intuitive

#

@drifting vault also, if you don't need camera specific override, just set it in default settings instead

#

Edit->Project Settings->HDRP Default Settings

#

that camera specific frame settings override is there only if you want to adjust this per camera

like for example if you use camera to render to render texture etc

it does work in motion without jitter as the motion gives the new temporal data it needs

glad tartan Apr 12, 2020, 4:35 PM

#

@barren marsh Yea DDGI will only be available for GPUs that support Realtime Raytracing. DDGI isn't available yet so we don't have access to it, from what I can tell it might have a bake feature that lets you save/cache the GI and this will work on any GPU, It just wont be realtime. This is still a good use since you will be able to have GI and a lot less work to have it. No lightmaps or even waiting a too long for the baked lighting to be done (This would still need a supported card to be able to bake it though)

turbid matrix Apr 12, 2020, 4:48 PM

#

I dunno if they will even allow baking it realtime in build, it's not been discussed on the presentation I think(?)

#

I think they did mention though that the once baked data in the editor is usable for realtime lighting on any gpu on actual build

it's just so random. I don't understand :PP

#

any ideas?

stiff star Apr 13, 2020, 8:43 AM

#

I was curious if the Scriptable Render Pipeline will replace the built-in renderer at some point, or if there has been any info on that?

#

I haven't used any SRP, but I understand that even the pre-made URP and HDRP are actual files you need to have in your game assets, and then require some tweaking from the settings to make rendering use these?

turbid matrix Apr 13, 2020, 11:32 AM

#

@stiff star you can check the pinned messages on this channel for both urp and hdrp docs

#

Both have some sorts of getting started -guide

stiff star Apr 13, 2020, 12:51 PM

#

Right, thank you, but my question was mainly concerning the first part. I was indicating it is currently an add-on, but I was wondering if it is planned to become the default?

turbid matrix Apr 13, 2020, 1:02 PM

#

@stiff star with few exceptions, new features only land to SRPs, so the idea is that the built-in renderer will slowly phase out. The idea is that most new projects would start with URP now

#

the built-in renderer is not going away as long as it has big userbase, so at least in past Unity has messaged that they'll keep it around until their stats indicate only tiny minority is using it anymore

stiff star Apr 13, 2020, 1:33 PM

#

I see. That's reasonable.
However, it doesn't seem all too intuitive to start out with the URP in a new project. While it might not be difficult if you're following a guide, it's still a very deliberate effort to do so, and I'd wager most all newcomers don't do so.

But that's not really a question, but a point of contemplation.

turbid matrix Apr 13, 2020, 1:48 PM

#

a lot of new things in unity are kinda making the engine tad harder to grasp for newcomers

#

it's partly due to the design and partly just because new systems do so much more so they are more complicated to begin with

wide forge Apr 13, 2020, 2:07 PM

#

Anybody knows why I got this error?
The type or namespace name 'ProfilingSampler' could not be found (are you missing a using directive or an assembly reference?)
And others

stiff star Apr 13, 2020, 2:28 PM

#

It's not about it being harder to grasp, but that they won't really achieve their goal of reducing users of the built-in renderer as long as it's not trivial to not use it.

turbid matrix Apr 13, 2020, 2:35 PM

#

"It's not about it being harder to grasp", " as long as it's not trivial to not use it" 🤔

#

I don't follow

#

doesn't the latter just mean the former thing

#

@wide forge never seen that error but out of my head... there could be some perf testing package on your project that's not compatible with LWRP package you have installed

#

so would double check the LWRP's dependencies and make sure you don't have mismatching perf testing or testing framework packages on your project

wide forge Apr 13, 2020, 2:37 PM

#

I just had to reset my package manager and reinstall stuff

turbid matrix Apr 13, 2020, 2:38 PM

#

also if you're on 2019.3, you should ust use URP directly 🙂

stiff star Apr 13, 2020, 3:55 PM

#

I mean, I create a new project in Unity, and it's not already the URP out of the box. Whether it takes 5 minutes or hours to set it up doesn't matter, since a lot of people will just use the built-in renderer they start with.

#

So if they would want to deprecate and phase it out, shouldn't the first step be to not make it the default?

turbid matrix Apr 13, 2020, 4:14 PM

#

I guess this is why they have URP and HDRP templates

#

I find them horrible starting points for a new project tho

#

they are nice for examining the setup tho

turbid matrix Apr 13, 2020, 4:39 PM

#

also if you use HDRP, all you need to do is install hdrp package and run hdrp wizard, make a new scene after it's done

#

of course this is not going to be obvious to new users

#

I feel that the hub's template system should work somewhat differently, basically you should just pick features and if you need sample content or not

#

like let you pick between built-in renderer / URP / HDRP, if you need VR, raytracing, ask for target device (mobile/generic desktop/highend) etc, then ask if you want to get sample content in the project

📎 unknown.png

fiery marsh Apr 14, 2020, 2:20 PM

#

@edgy harbor In any pipeline if you obtain the material reference you should be able to use material.SetColor("_SpecularColor", color). See https://docs.unity3d.com/ScriptReference/Material.SetColor.html. There's also SetFloat, SetTexture, SetVector, etc for other property types. In order to find the property name to use you might need to look at the shader, e.g. https://github.com/Unity-Technologies/Graphics/blob/master/com.unity.render-pipelines.high-definition/Runtime/Material/Lit/Lit.shader

means we can get the versions as soon as they are out, in the old system we'd stack up updates for next release

#

yeah I can see how that can suck from asset dev's perspective

#

from users POV it's great

#

unless you rely on 3rd party stuff

#

but I avoid 3rd party stuff because it's always outdated anyway:p

viral eagle Apr 14, 2020, 11:41 PM

#

Until they try to use one asset that needs 7.2.1, and another that needs 7.1.8, and another that needs 7.3.1..

#

Wouldn't be if they could do things in a way that's maintainable.

valid dock Apr 14, 2020, 11:41 PM

#

3rd party assets are a big built-in value of the Unity ecosystem

turbid matrix Apr 14, 2020, 11:41 PM

#

until you actually use them in production..

#

then it can be huge time sink

#

you get into situations Jason just mentioned

valid dock Apr 14, 2020, 11:42 PM

#

i mean, choose them carefully...

turbid matrix Apr 14, 2020, 11:42 PM

#

it was also an issue before the package system

#

I can't wait until asset store publishers are forced to use upm system

#

no more 3rd party assets messing up my projects

viral eagle Apr 14, 2020, 11:43 PM

#

At my last company I treated it like buying code from someone we fired. Expect to own it, so choose wisely, but it's still a ton faster than writing it all yourself.

#

No, you'll just have even more breakage..

turbid matrix Apr 14, 2020, 11:43 PM

#

I wasn't talking about compatibility now

#

but actually not letting asset store assets mess up projects

#

I absolutely hate the assets folder bloat

#

Unity should have enforced that stuff even on the current system

viral eagle Apr 14, 2020, 11:45 PM

#

Yeah, having them in packages will be nice for that reason, but it's going to be an even bigger mess if it's really ever just a bunch of packages all getting released on completely different schedules, breaking each other, never having a single version of everything you need aligned to all the same versions, etc.

#

Lot of issues with people randomly renaming and moving stuff will be gone though.. hopefully.

turbid matrix Apr 14, 2020, 11:45 PM

#

I dunno, with packages you can actually have dependencies

#

so it's not as bad as current system on that way

viral eagle Apr 14, 2020, 11:46 PM

#

Yes, you just can't resolve them.

valid dock Apr 14, 2020, 11:46 PM

#

by sometime in 2023, everything ought to be moving nice and smoothly

#

after we get through this transition

viral eagle Apr 14, 2020, 11:46 PM

#

I have doubts..

turbid matrix Apr 14, 2020, 11:46 PM

#

yeah, I've seen that most asset publishers hate this current setup

#

but yeah, I don't really rely on lots of assets anymore as they just are a huge risk

viral eagle Apr 14, 2020, 11:47 PM

#

stability comes from architecture decisions, and they haven't made a stable architecture.

turbid matrix Apr 14, 2020, 11:47 PM

#

1/3 of the useful assets I've bought have been deprecated shortly after buying them

#

and getting updates is always with huge delay

#

it's just not nice for users POV at all

#

so, better stick to stock stuff or maintain stuff yourself :p

valid dock Apr 14, 2020, 11:47 PM

#

lol that isn't an option for everyone

#

Unity is used by teams of all different sizes

turbid matrix Apr 14, 2020, 11:48 PM

#

yeah, I've learnt this the hard way 😄

valid dock Apr 14, 2020, 11:48 PM

#

sometimes using asset store packages is the only way

turbid matrix Apr 14, 2020, 11:48 PM

#

shouldn't be

viral eagle Apr 14, 2020, 11:48 PM

#

I mean, you could spend 3 years writing a shader as fast as MicroSplat, but you likely wont.

valid dock Apr 14, 2020, 11:48 PM

#

i mean... the only other alternative is Unity themselves covering every kind of functionality smaller teams and independent developers could need

turbid matrix Apr 14, 2020, 11:48 PM

#

is microsplat compatible with latest HDRP?

#

does it work with raytracing?

viral eagle Apr 14, 2020, 11:49 PM

#

which do you consider latest?

turbid matrix Apr 14, 2020, 11:49 PM

#

8.0.1 I guess 😄 but I know asset store publishers avoid unity betas so 7.3.1 I guess

viral eagle Apr 14, 2020, 11:50 PM

#

it's compatible with 7.3.1

#

I've had to restrict it down to one version of the current unity version + LTE releases. So right now URP 7.2.1 on Unity 2019.3, and LWRP on 2018.3..

#

It was getting to be complete madness trying to work across essentially 12 pipelines without an abstraction layer (basically, I was writing surface shaders for Unity, since they didn't).

#

All preventable. This is unity's mess, and forcing people into a shader graph is not an answer.

#

especially that shader graph, geeze..

valid dock Apr 14, 2020, 11:51 PM

#

yea it sounds bad

#

and whether or not you like to use asset store packages, there is no arguing that it isn't a fundamental part of Unity's ecosystem

viral eagle Apr 14, 2020, 11:52 PM

#

but yeah, if you want to script kid it and develop on the latest alphas.

finite nexus Apr 15, 2020, 2:23 AM

#

Hi guys, I'm trying to create a setup where a shader pass writes to an off-screen buffer, and then a second shader pass that writes to the screen can sample from that buffer

#

is this possible to do in URP? I searched pretty thoroughly but couldn't find the intended way to write to a separate buffer, and I'd hope that I wouldn't have to create a custom render pipeline for such a simple setup

turbid matrix Apr 15, 2020, 2:31 AM

#

@finite nexus if https://docs.unity3d.com/Manual/class-CustomRenderTexture.html is fine for you, you can even write shader graphs (on URP, not on HDRP) that write to CRT and then sample that on the other shader

finite nexus Apr 15, 2020, 2:32 AM

#

@turbid matrix that looks like it should work for what I'm trying to do, thank you!

turbid matrix Apr 15, 2020, 2:46 AM

#

@finite nexus this uses CRT: https://github.com/tim-neville/Snow-Tracks-ShaderGraph-Unity-2019.1

#

(and SG on LWRP)

finite nexus Apr 15, 2020, 2:50 AM

#

@turbid matrix do you know how to indicate at what point in the pipeline the CRT should be updated?

turbid matrix Apr 15, 2020, 2:53 AM

#

@finite nexus wait, you need actual on world rendering to the material?

#

then that CRT isn't the right thing

#

CRT is just for writing shader directly to the render target

finite nexus Apr 15, 2020, 2:53 AM

#

oh, I see

#

yeah I need to render world geometry data to the buffer

turbid matrix Apr 15, 2020, 2:54 AM

#

what kind of data?

finite nexus Apr 15, 2020, 2:54 AM

#

in this case, world space position

#

in my shader I want to sample the world space positions of other areas on the screen for each fragment

#

but normally you can only access the world space position of the current fragment

#

I just found this article describing Scriptable Renderer Feature which I think is what I want https://alexanderameye.github.io/outlineshader

prisma sleet Apr 15, 2020, 4:19 AM

#

@turbid geode I realize it's been like...weeks, but I'm also trying to port something that used OnRenderImage to the scriptable rendering pipeline. Fact is, OnRenderImage is simply not supported in the SRPs. I am a complete noob at this, but am investigating using the PostProcessing package found in the Unity Package Manager, which I believe is meant to be a replacement for OnRenderImage (amongst other things). However, it works completely differently, of course, so it's not an easy job.

scarlet hull Apr 15, 2020, 7:54 AM

#

@prisma sleet The post processing package should not be used anymore with SRPs, as they have their own integrated post process.
You might want to look for the events here : https://docs.unity3d.com/ScriptReference/Rendering.RenderPipelineManager.html

Hey everyone!
Hope corona is treating you and your loved ones well.

I have this question, anyone can help with this?
Through this transparent material I can see the shadow of the plate but not the plate itself.

Any idea why would this be happening?

📎 unknown.png

drifting vault Apr 15, 2020, 10:25 AM

#

@fading rose wow wow, with materials settings use your plate?

true zealot Apr 15, 2020, 10:30 AM

#

looks like your glass is writing to depth when it probably shouldn't (unless you rendered it in a different order)
and your plate, etc, is marked transparent for some reason

fading rose Apr 15, 2020, 10:55 AM

#

Thanks. I have put all the plates and glassware on one material to reduce draw calls, probably that is why.

#

this is the material setup.

📎 unknown.png

#

However disabling depth write doesn't fix anything and it is necessary in order to render the objects properly. Without it you get serious errors.

Perhaps I should not put these two together. I will do that.

📎 unknown.png

scarlet hull Apr 15, 2020, 11:09 AM

#

You're using refraction.

#

Refraction works by sampling the color buffer that was saved with only the opaque objects rendered. Since your glass has refraction, even if the plate (that uses the same material) is rendered before, it is not in the refraction color buffer, and is not visible through the glass

#

Grouping objects together is generally a good idea, but don't mix opaque and transparent

fading rose Apr 15, 2020, 11:15 AM

#

If I create a new material with the same textures (but now opaque material instead of transparent) will the textures be loaded in memory twice?

late schooner Apr 15, 2020, 11:19 AM

#

nope

#

assuming you actually use the same textures and not copies

fading rose Apr 15, 2020, 11:27 AM

#

Of course the same. 🙂 Thanks

Hi, i am new with urp (7.1.8) and have question, maybe anyone can help? What is right way to render image from camera to renderTexture only once from method call? I explore a lot of urp-examples today, they all used ScriptableRendererFeature/ScriptableRendererPass, that execute every frame, but its overhead for my case. (i want render camera image to texture, than blur it with command buffer and use as background in ui).

hazy yoke Apr 15, 2020, 7:42 PM

#

There should be a slot on the camera component itself that you can specify a render texture target

Brrr

#

The render objects feature stencil override doesn't work

#

it keeps resetting when I leave the inspector window

hazy yoke Apr 15, 2020, 9:31 PM

#

@candid basin try setting inspector window to debug mode before doing it?

#

and not switching back I mean, just staying in debug mode

candid basin Apr 15, 2020, 9:33 PM

#

that works

#

Yeah if I enable it in debug, then leave debug, it stays

#

but in normal mode it resets back whenever I deselect the renderer

hazy yoke Apr 15, 2020, 9:35 PM

#

so the inspector window is changing data

#

which it does a lot

lyric ravine Apr 15, 2020, 9:35 PM

unsure, if its an exposed value on the normal inspector then maybe? This is just coming from memory on my previous project

hello!

#

I just updated hdrp to urp a while ago

#

And I dont find where the procedural sky component is

#

was it removed?

#

also what happened with volumetric fog?

#

oh I found out what happened to the skybox

dawn sorrel Apr 15, 2020, 11:38 PM

#

what happened to the skybox

vernal burrow Apr 15, 2020, 11:43 PM

#

I didnt found the procedural skybox component, but I just noticed that you have to create a material for it

#

but now, what about the volumetric fog?

dawn sorrel Apr 15, 2020, 11:46 PM

#

no clue, i'm a beginner to those

I just updated hdrp to urp a while ago
@vernal burrow so are you on URP now?

yes

you don't really update from hdrp to urp so wasn't clear what you meant

there's no volumetric fog on urp

vernal burrow Apr 16, 2020, 12:31 AM

#

oh really?

#

I thought it was there

turbid matrix Apr 16, 2020, 12:31 AM

HDRP is WAY more featured than URP

vernal burrow Apr 16, 2020, 12:32 AM

however HDRP doesnt have camera stacking

technically it does

technically you can do this via scripting on current HDRP already but it's totally undocumented and things may break

#

I'd wait for that PR to land or try the PR version first

vernal burrow Apr 16, 2020, 12:34 AM

#

I would like to do it, but with out documentation, I cant do anything, so I guess I will wait

#

the thing is that using 2 cameras in hdrp is really expensive

turbid matrix Apr 16, 2020, 12:35 AM

#

camera stacking isn't something HDRP team is recommending for game use though

#

it will be, even with stacking

vernal burrow Apr 16, 2020, 12:35 AM

#

with one cam I could get 250 fps, but with 2 I get 60 or less

turbid matrix Apr 16, 2020, 12:35 AM

#

why do you need it?

vernal burrow Apr 16, 2020, 12:36 AM

#

for adjusting camera fov in gun view and in main camera view

turbid matrix Apr 16, 2020, 12:36 AM

#

you can already do that via shader

vernal burrow Apr 16, 2020, 12:36 AM

#

with a post processing shader?

turbid matrix Apr 16, 2020, 12:37 AM

#

with shader graph shader

#

https://github.com/Unity-Technologies/fpssample does this for example

GitHub

Unity-Technologies/FPSSample

A first person multiplayer shooter example project in Unity - Unity-Technologies/FPSSample

#

they render a tiny gun, then reproject it to appear bigger with custom fov

vernal burrow Apr 16, 2020, 12:37 AM

#

but I mean, how can I render the shader on screen

#

as I know, the only way to do that is with custom postprocess or with screen overlay canvas UI

turbid matrix Apr 16, 2020, 12:38 AM

#

alternatively, I think you could just render the gun using HDRP custom pass on later injection point so it will render on top of existing things

#

all in all, you'd want to avoid the camera stacking for a thing like that

#

and if anyone would ask me, I wouldn't recommend even doing the gun on top of everything hack

vernal burrow Apr 16, 2020, 12:39 AM

#

I already tried that, but the fov isnt working, however the perfomance increased a lot when I tried that

turbid matrix Apr 16, 2020, 12:39 AM

#

you can fix the gun penetration by just moving the gun out of the wall

vernal burrow Apr 16, 2020, 12:39 AM

#

what would you sugest?

#

remember that the scale of guns are not the same for all sort of guns

#

some could be larger, other smaller

turbid matrix Apr 16, 2020, 12:40 AM

#

yes, but I mean, you can't physically push the gun through a wall, you'd point the gun elsewhere in that kind of case

#

I'm always all about more immersive and believable setups myself

#

I've done the camera stacking gun hack in past and I really hated it

#

it really messes up with depth perception when the gun sinks into boulders etc

#

of course that hack is the easy way out

vernal burrow Apr 16, 2020, 12:42 AM

#

ahh I see, I think same way as you, but there are some things that cant be fixed easily

#

one of the solutions that I thougt was adding a collider at the barrel of the gun

turbid matrix Apr 16, 2020, 12:43 AM

#

anyway, if I needed that, I'd try experimenting with custom passes first

vernal burrow Apr 16, 2020, 12:43 AM

#

it might work, I havent tested that

#

yes, I did that yesterday, but today I will work on it again

turbid matrix Apr 16, 2020, 12:43 AM

#

if you use hdrp that is

#

📎 gyuiaw.PNG

#

📎 tftyu.PNG

#

the arrows represent what camera draws to what texture

turbid matrix Apr 16, 2020, 12:59 AM

#

I wonder if it's because you are rendering to the same RT than would have been on the screen

#

maybe adding extra RT and alternating between the two RTs (for each camera) would fix that?

tranquil gate Apr 16, 2020, 1:00 AM

#

i've already tried it... it didn't work

rich spade Apr 16, 2020, 6:39 AM

#

@tranquil gate I can't imagine that it would stack due to the nature of it, you could do something similar in a shader though. Depending on what your trying to achieve exactly, you might not even need an RT.

torn harbor Apr 16, 2020, 10:16 AM

#

@tranquil gate i tried to reproduce (urp 7.2.1) in two ways -

use first camera output as renderTexture and second camera to render scene, like it describe in documentation
use renderFeature to manually blit screen to render texture.
And both ways work, maybe i misunderstand something, sorry then) 🤔

hardy lily Apr 16, 2020, 12:27 PM

#

Kind of confused here. I thought Unity's Premultiply blend mode is (One) + (0neMinusSrcAlpha) and not just, well, Alpha, yet again, or (SrcAlpha) + (0neMinusSrcAlpha). In premul, I thought the RGB and the alpha of the image are independent and not together like in alpha. Is premul, by chance, deprecated, or is this a bug?

#

Because if this is a bug, where do I go to fix it?

#

This is for URP, by the way.

@glad tartan yeah, I tried that earlier

#

it's still slower than DX11

Yea, I expect it will be a while before it's on par or better than DX11

turbid matrix Apr 16, 2020, 3:34 PM

my current proto on DX12 (no DXR): 273fps - 3.66ms
DX11: 338fps - 3.0ms

#

on that 2020.2.0a7 that is

glad tartan Apr 16, 2020, 3:35 PM

#

It's similar for me. This is without Hybrid renderer or anything extra. Just DX12 vs DX11

#

what will the next version number/name for HDRP be with 2020.2
10.0.0
Wonder if it will be raised like this or formatted different

turbid matrix Apr 16, 2020, 3:41 PM

would expect 9.x to become the releases for 2020.2

right now 9.x still works on 2020.1 but that's kinda how these things have went in past too

#

at some point they need to add feature that will not work on the earlier version

glad tartan Apr 16, 2020, 3:51 PM

#

yea currently 9.x.x is for 2020.1
For 2020.2 it might get bumped to another version, as each editor have their own package version
GitHub will bring the message

How do I enable the SRP Batcher in unity 2019.3 with hdrp (7.1.8)?

glad tartan Apr 16, 2020, 6:11 PM

@short thorn It's enabled by default

Hi, does Custom Render textures work with HDRP?

#

Or I need to use Graphics.Blit instead? In that case, what is the difference actually? I want to use some compute simulation shaders on a same texture

Trying to import Unity graphics (formerly ScriptableRenderPipeline). Tried both the "Latest-Green" and master. I'm getting errors regarding CSharpToHLSL.cs; using the most recent alpha build 2020.2.0a7 com.unity.render-pipelines.core\Editor\ShaderGenerator\CSharpToHLSL.cs(2,7): error CS0246: The type or namespace name 'ICSharpCode' could not be found com.unity.render-pipelines.core\Editor\ShaderGenerator\CSharpToHLSL.cs(286,57): error CS0246: The type or namespace name 'TypeDeclaration' could not be found ... etcTried importing the ICSharpCode.SharpZipLib.dll directly into project plugins folder (a solution mentioned online years back) but that didn't work either

#

oh wow

#

they actually started fixing the microstuttering on Unity

#

The fix for DX11 in the player is part of the first 2020.2 alpha. Other platforms are to follow (timelines TBD).

#

just to note about this that this is basically what happens all the time, basically the deltatime keeps overshooting and it's always around vsync but never at it

#

this has made some PP algos a pain as you can't get smooth velocity from motion vectors

silent mortar Apr 16, 2020, 10:48 PM

#

Speaking of microstuttering anyone have a solution for microstutter/flickr whatever the world is going on here?

Would love some assistance it is driving me crazy, very hard on the eyes the shifty pixels.

It is affecting both 2D tiles and sprites both.

I'd just check the entirety of that doc and make sure you've done everything, including the ones that are easy to miss like: Windows version is at least 1809

vernal burrow Apr 17, 2020, 3:11 AM

#

I checked it twice

#

and I got that version installed

#

however I noticed somtething on the HDRP wizard, but I think it is caused beacause of that error

#

it says that there is an issue with dxr resources

#

I clicked fix and it imported something

#

it was gone

but when I opened the wizard again to see if I missed something, the error was there again

turbid matrix Apr 17, 2020, 12:48 PM

#

@winged monolith you can see the details on the bottom part when you click at any point on that graph

#

if you profile on editor, there's a huge overhead there

winged monolith Apr 17, 2020, 1:18 PM

#

@turbid matrix the details of the editor dont seem to open in the hierarchy

turbid matrix Apr 17, 2020, 1:31 PM

#

it's like that for a reason

#

you can make it show that stuff but the point is that you shouldn't worry about things that happen on editor side unless you write actual editor tooling

#

always profile on actual game build if possible

winged monolith Apr 17, 2020, 1:42 PM

But if it is so slow that I cannot work on the game, it wont help me...

has the scripable pipeline source code that was on github been removed?

I wanted to figure out how to do something with GetAdditionalLight() in URP but the code explaining how that might work has kinda vanished lol

hi guys, my custom Scriptable Render Feature works perfectly in the scene view, but doesn't seem to do anything in the game view (whether in play mode or not). any ideas why this might be happening?

turbid matrix Apr 17, 2020, 4:53 PM

#

@stoic depot https://forum.unity.com/threads/srp-repository-migration.861625/

#

that explains the reasons behind the repo move

#

TL;DR: new repo now uses Git LFS so cloning it will not take forever anymore

stoic depot Apr 17, 2020, 4:55 PM

#

fair

faint nymph Apr 17, 2020, 4:55 PM

Does the repo contain textures or something?

turbid matrix Apr 17, 2020, 4:58 PM

#

yes, there are tons of small binary files that are now handled by lfs

#

so you can't just download the zip from github anymore for example

faint nymph Apr 17, 2020, 4:58 PM

Ahh I see

I'm testing this change on 2020.2 but I'm frankly not seeing it:
Improved Time.deltaTime consistency for D3D11 graphics API

#

I wonder if it's tied to SRPs since my test setup is on blank scene with built-in renderer

#

there's comparison from DT captures along time between 2020.1.0b5 and 2020.2.0a7:

📎 unknown.png

#

it's bit noisy but one can tell there's not really any notable difference on DT consistency between the two

#

weirdest thing is that there is however happened a notable difference to DT consistency during 2019 cycle

true zealot Apr 18, 2020, 1:01 AM

#

gotta make some box plots

turbid matrix Apr 18, 2020, 1:06 AM

#

here's the diff between 2019.2 and 2019.3 (note that it's different scale due to way more noise on 2019.2):

📎 unknown.png

#

Basically every Unity version up to 2019.2 represents 2019.2 on this graph, and every unity version on that is 2019.3 or newer looks like 2019.3 graph here

#

what baffles me is that the improvement should only be at 2020.2 so it's totally possible that there's some other change that dramatically changed this earlier already

#

I also tested 2020.2 with DX11 and DX12 and there's no difference

#

so I'm guessing the logical explanation is that the DX11 fix hasn't even landed yet / to be included on currently available 2020.2.0a7

#

it's not mentioned in the release notes either, only on 2020.2 new features thread

#

well, this explains something: The change actually made it into 2020.2.0a8 and I didn't realize we only realized 2020.2.0a7.

#

so, it's only getting better I guess 😄

#

it's also possible that the fluctuations on empty scene don't really correlate that well on scenes loaded different frame loads on cpu

#

I mean empty scene would have pretty consistent cpu load in comparison to say game that has various systems taxing cpu at times

split spire Apr 18, 2020, 10:27 AM

@drifting vault so the whole detail tab is not used in HDRP?

cobalt idol Apr 18, 2020, 5:20 PM

Is there any way to apply a RP in the editor scene window? More specifically, I have a post-processing pass I would like to see in scene view. Alternatively, is there a way to override the materials used in scene view?

#

I saw an old 'hack' based on using LOD, whereby you could configure an ultra high LOD for your 'in scene' material, and then turn the game to a lower LOD so it falls back to the actual shader you want - but these seems clunky and I wondered if there was a better out of the box solution

candid basin Apr 18, 2020, 6:34 PM

#

Uhm I don't know 100% for sure if this is the same thing or the thing you mean but I do this in my project @cobalt idol

#

📎 hSaHXYjpLg.mp4

#

The red tinted texture is 1 pass

#

outline pass is another one

#

So I have this material that adds the outlines

#

📎 unknown.png

#

And it's shown in the scene view

cobalt idol Apr 18, 2020, 6:58 PM

#

thanks @candid basin , is that inspector your SRP object?

candid basin Apr 18, 2020, 6:59 PM

#

That's my forward renderer

#

and so the outline pass is one of the renderer features

cobalt idol Apr 18, 2020, 7:00 PM

#

(just waiting for unity to load)

candid basin Apr 18, 2020, 7:00 PM

#

in older SRP versions it might look a bit different, the renderer features will be in a list UI

cobalt idol Apr 18, 2020, 7:05 PM

#

thanks, I just checked and for me it has the list UI form

#

I'm on URP 8.0.1

candid basin Apr 18, 2020, 7:05 PM

#

😮

#

oh you mean the UI is the same as me?

#

I'm on 7.3 I think

maybe this article could help with a feature like that

Outline Shader

#

you probably don't need an outline but the feature in the article is similar to the one I use currently

cobalt idol Apr 18, 2020, 7:09 PM

#

The post process itself works fine - but only in the game view 🙂

#

it doesn't get applied in the scene view

candid basin Apr 18, 2020, 7:09 PM

#

the post process is also with a renderer feature?

cobalt idol Apr 18, 2020, 7:09 PM

#

yeah

candid basin Apr 18, 2020, 7:10 PM

#

Hm I don't think I ever encountered that

cobalt idol Apr 18, 2020, 7:11 PM

#

the render feature includes a separate rendering pass and a full-screen post process

#

ends up like this in game view:

📎 unknown.png

candid basin Apr 18, 2020, 7:11 PM

#

pixelation?

#

or the lines

cobalt idol Apr 18, 2020, 7:11 PM

#

both

candid basin Apr 18, 2020, 7:11 PM

#

looks great btw haha

cobalt idol Apr 18, 2020, 7:11 PM

#

thank you 🙂

#

I'm doing a slightly different pixelisation method, which doesn't involve rendering to a low resolution render target once per object

#

but it does require one full screen pass

#

either way, it looks like my scene editor doesn't actually apply the render feature, only the game window does (unless there is a subtlety I am missing, like render target 'active' being different between them)

candid basin Apr 18, 2020, 7:14 PM

could you take a look at this

is what you're doing much different?

maybe something with the CameraTarget, not sure

cobalt idol Apr 18, 2020, 7:15 PM

#

ill have a read through

#

btw, I found a lot of inconsistency with blit when upgrading to 8.0.1

candid basin Apr 18, 2020, 7:16 PM

#

I hope my effects don't break when moving 🙂

cobalt idol Apr 18, 2020, 7:16 PM

#

It seemed like depending on the render target it would either be a dynamic draw or a copy texture, and would flip uvs accordingly

#

it broke all of mine 😄

#

It looks very similar - there are a few extra blit calls but apart from that the structure is the same

atomic wing Apr 19, 2020, 4:30 AM

Anyone use HDRP? I cant figure out what that weird auto-exposure effect is that increases exposure when looking down, and makes everything dark when looking level to the ground. It doesn't seem to be auto-exposure or AO

daring lodge Apr 19, 2020, 5:20 AM

#

anyone have a way of drawing a single skinned mesh renderer to a camera without taking 10ms on hdrp?

#

Right now if I call a Camera.Render(), it takes 10 whole ms to render the single object

#

If I try to use CommandBuffer's DrawRenderer() function, it draws to every camera

daring lodge Apr 19, 2020, 6:49 AM

#

Got it!

#

Just had to use a non-HDRP material in the command buffer

#

works great

snow lake Apr 19, 2020, 4:53 PM

Good day all,

I'm having an odd rendering effect in the editor play mode for HDRP when using entities in Convert and Destroy mode (Inject doesn't work for Unity Physics). The rendering works fine until I enter play mode where light bouncing/ambient lighting seems to stop working:
Example: Editor - Edit Mode

📎 SPOILER_unknown.png

#

Editor - Play Mode On:

📎 unknown.png

#

This only occurs when I changed all of the game objects to ECS Entities. It works fine in Convert and Inject GO mode but then collisions break in Unity Physics (no collisions).

ember breach Apr 19, 2020, 5:00 PM

#

Currently entities does not work with this lighting, try making your own shader graph and using it on your entities, standard materials does not work with lighting

snow lake Apr 19, 2020, 5:00 PM

#

Damn

#

Okay, thanks!

#

So much for things working out of the box lol.

ember breach Apr 19, 2020, 5:09 PM

#

its in preview so there are many things that are going bad with it 😄

snow lake Apr 19, 2020, 5:10 PM

#

Yeah but I find it funny that something that's promoted as much as HDRP doesn't work with ECS, which is also the "new way of doing things".

ember breach Apr 19, 2020, 5:13 PM

#

Like almost everything works, you just have to have right setup, the only thing currently that holding our studio back from using full stack is that NetCode using new Physics is not running at fixedFrames, so it runs on the client side of things, its pretty common issue and the staff is looking into it so hopefully they get it working so we can do some cool stuff with it, but there is not much point in using all of the feautures right now, basically we are now using URP only, no ECS etc. for now.

Ah okay.

turbid matrix Apr 19, 2020, 6:23 PM

@snow lake hybrid rendering is still sketchy

snow lake Apr 19, 2020, 6:25 PM

#

Is there a way I can use Unity.Physics while still having the world run in GO mode? Havok is complaining that it only works with entities.

#

Convert and Inject just breaks it outright.

turbid matrix Apr 19, 2020, 6:26 PM

There are ways to mix go rendering and ecs physics
