[Released] Lux URP Essentials

unity version used 2019.2.01f.
lwrp 6.9.1
billboard shader working in editor but not on android built

 

Hi!, Just wondering if these shaders have been tested on entities running via URP, DOTS and the Hybrid Renderer V.2? I'm specifically interested in the Transmission shaders

 

@larsbertram1 One thing that would be cool if the Terrain Lit shader's procedural texturing supported using world-space UVs.

I'd love to tile my terrain into smaller pieces and have adjacent terrains with the same texture layer painted on the seam, without having an obvious seam.

 

Hi! I will say it again, loving the shaders. However is it possible to add some shadergraphvertex magic to one of your shaders. For example i want to add some vertex magic to the cloth shader?
I'm not yet very comfortable with programming shaders without the shadergraph. Can the cloth shader be converted to shadergraph so i can add stuff or is there any other solution?

 

Hello,

Just wanted to say I keep getting this message. I am sure you will take care of this in a future update but just wanted to let you know in case you hadn't seen this.

Assets\Thirdparty_Assets\Lux URP Essentials\Lux SRP Grass Displacement\Scripts\GrassDisplacementRenderFeature.cs(124,24): warning CS0618: 'ProfilingSample' is obsolete: 'Please use ProfilingScope'

Thanks!

 

Hello.
Im trying to make a customization for my game. How would i do to make a makeup customization using masks with the Lux URP shaders?

 

hey, just an idea for future update to add an option to decals to use some kind of atlasing

 

are you using SRP batcher?
https://forum.unity.com/threads/released-lux-lwrp-essentials.712619/page-17#post-6394558

 

yes, the srp batcher is fully supported.

 

as Lux URP Essentials support the SRP Batcher there is no atlas option see here for further details.

 

Version 1.5 is on its way.

### Added:
- Decals: HQ sampling added to avoid artifacts at depth discontinuities.
- Skin: Ambient back scattering added.
- URP 10.2. preview package added which supports SSAO and Shadowmasks.


HQ Sampling disabled: 2x2px artifacts around edges in the depth buffer.


HQ Sampling enabled: 2x2px artifacts are gone.

 

@larsbertram1 you could add a version.txt file to your asset like other assets do, this way we know which version we have installed.
What did you change to the hlsl shaders? the upgrader failed miserably on some hlsl and since I have custom graphs of my own I was wondering what's break it so I can fix it and the console gives no hint.

 

for the 10.2 preview? a lot: extended structs, replaced function calls, changed pragmas... more or less it was a complete diff compare.

 

oh wow so urp 10 is a completely new beast

 

Version 1.5 is available.

 

na, not completely new, but a lot of changes had to made. just take a look as it is available now

 

you can just choose the tiling wisely, can't you?

 

Hi, I get 2 shader errors in Editor after updating to Lux 1.5 and URP 7.5.2.
I think I updated from Lux 1.45 and URP 7.4.1 that worked well.

I only use the Fast Outline shaders.

Errors print for are all platforms I have installed: Windows and WebGL

Shader error in 'Lux URP/Lit Extended': undeclared identifier '_Surface' at /Code/Unity/.../Library/PackageCache/com.unity.render-pipelines.universal@7.5.2/Shaders/LitForwardPass.hlsl(141) (on d3d11)

hmm, works well for me here. "_Surface" sounds like an URP 10 thing. afaik it is not used in shader code in URP < 10.

 

with the 1.5 version, still some pink in urp 8.31

 

@laurentlavigne i haven't looked into urp 8.31. only 7.41 or 10.2 are supported. 8.x and 9.x are just wasted time.

 

@larsbertram1 Is your package suitable for use on mobile? Specifically, I am interested in using your skin shader to add some realism to my characters.

 

that should be fully ok. especially the skin shader lets you fade skin shading over distance so you can swap back to regular pbr shading at lower lods. minimum urp i recommend is 7.4.

 

explain

 

not stable, intermediate releases - whatever you wish. look up the corresponding forum threads.
as far as i know neither 8 nor 9 brought significant changes. so i dropped them.

 

i am having weird glitches with v8.2, 8.3 not so much. v10 is stable?

 

Hi,
Is it possible to use a direction map in hair shader?

Currently, I see two options for my project (it's not a game, FPS is not important in my case):
Solution A: built-in pipeline + Lux Plus – Physically Based Shader Framework
Solution B: URP + lux urp essentials

Problems:
Solution A:
1.hair shader works in the metallic workflow, I mean there are no spec map/color parameters. (it's the main problem)
2.It's not supporting alpha blending as I know and on another hand, dithered opacity has no randomness so it always makes dithered dots in the same position during the frames. (fixed camera position)
it would be highly better if there was some randomness in the dithered points/dots position so when we using TAA, this randomness will make a nice and cleaner opacity illusion.

Solution B:
It does not support direction map (tangent map)

So, What's your suggestion?
(I also should mention that I know nothing about writing the shaders so if this request has a cost, I will gladly pay for it because this is the only problem I have in my project and I can't find any solution for it)

 

if built in or urp should be the first question here. or hdrp which has its own hair shader built in.
the anything else can be negotiated.

 

well, it is the future.

 

Thanks for your quick response
HDRP is not in my options, because I found some problems in other parts of my project with HDRP.
The best solution for me is the built-in pipeline and having a shader that works with the built-in pipeline. if it's not possible so I have no choice but to switch to URP.
I understand that what I'm asking for may not be useful for others. but It's a huge problem in my project, I tested all possible solutions all over the net and get nothing.
the only one shader that works perfectly is the HDRP hair shader, but I have some other problems with HDRP and can't switch to HDRP.
Is it possible to have a spec workflow instead of metallic for the Lux "built-in" hair shader?
Thanks a lot

 

ok you meant stable as in not changing all the time, I understood it as unreliable performance or crashy

 

Hi @larsbertram1 , I'm using the latest Lux (1.5) with Unity 2020.2.0f, URP 10.2.2 (verified) and I've got these errors :



Are you aware of this issue ?

 

no, as my dev project uses upr 10.2. (without the additional .2).
but i updated to 10.2.2. and get no errors... so it looks as if you haven't updated the shaders properly? did you import the urp10 preview package?

 

Unity2020.2f1+URP 10.2.2 + LuxURPEssentials_URP_10.2.Preview.unitypackage no errors

 

thanks for your feedback!

 

I will try to import the preview package instead.. I've used the 10.2.2, which is the verified version for Unity 2020.2.0f. Thanks for the tip!

 

@larsbertram1 btw, how can I modify your transmission shader to use metallic setup also?. Since it uses specular only and most of textures come now days with metallness workflow

 

Hello i am trying to use Billboard Shader but i getting lots of errors in the console, i am using 2020.02 version, is this some incompatibility with the version?

Note that the shader is working and the images are displayed.
Although there a a few demo scenes with pink material rendered.

If so is there a workaround?

Thanks!

transmissive materials hardly ever are metals... so going with metalness here just wastes some control over the material (although the shader does not support a specular map but just a single color value).
but of course you can hack the shader:

• comment "#define _SPECULAR_SETUP 1".
• inside the "InitializeSurfaceData" function you would have to sample your metal mask and then set outSurfaceData.metallic accordingly.
• the lighting function then should take care about the conversion from metallic to specular when it sets up the BRDF data.

 

the code from the console you have posted does not show any error in the shaders.
it just tells you that there are too many keywords used by the shaders in your project.
so most likely you have installed a bunch of assets with custom shaders which request keywords.
so try to get rifd of these or istall lux urp essentials in a fresh project.

if there are pink materials this might be caused either:

• by the keyword issue (which i doubt)
• by the fact that you did not install the urp10preview package (which i guess) 2020 uses urp 10 and needs the preview package.

 

You are right, i have a few other packages installed on the project.
Too much shaders then.

For the preview i installed it and everything is working now

And i have tried a few Lux shaders in a few scenes and they are working as expected!
Awesome job!

Thanks for the quick reply.

 

i would go over the packages and look what you really need.
then look if the corresponding shaders use global shader keywords. most shader should get away with local keywords which do not count.
also make sure that you do NOT HAVE A SINGLE standard rp shader in your project as it will need an incredible amount of keywords like fog, forward rendering or instancing.
some packages come with shaders for built in, urp and hdrp. make sure you delete built in and hdrp shaders.
even if you use e.g. unity's terrain tools: these will add old school shaders and cost you a bunch of keywords.

great!

you are welcome

 

Wow It works, Thanks!. One more question the mask(R) what is it supposed to do, obscure the Transmision effect or something else?.

 

mask r lets you switch between regaular and translucent lighting. have a look at the demo: on of the candles there mixes both lightings within a single material = 1 draw call and no additional set pass call

 

I think there's a slight bug in the skin lightning normal calculation.

If you have "Enable Normal Map" on but "Enable Diffuse Normal Sample" off, the normals are completely flat, ie not using the normal map.
In "Lux_Lighting_Skin.hlsl" in function Lighting_half, it looks like the logic is with enable normal map on and diffuse normal off, the "diffuseNormalWS" gets set to the passed in normalWS, but then normalWS is set to the unpacked and transformed worldspace normal. Doesn't the diffuseNormalWS need to be the same when disabled?

If I move that block of sampling the normal map and transforming it to the top of the if(enableNormalMapping) statement, then that looks like the intended logic as well as the shader looks to output correctly.

 

i see what you mean.

but actually this is not a bug - it is just a different concept here:
while you would use the crisp specular normal to light the diffuse the shader uses the "super" smooth per vertex normal.
thus the diffuse "normals are completely flat" as you mentioned.

doing it the way you expected might be the more obvious solution. i am not sure. just let me know what you think.

EDIT: i just uploaded version 1.51 which lets you choose between vertex and specular normals if diffuse normal sampling is disabled

 

I am having similar issues using Lit Extended Uber. Smoothness seems to be gone or ignored...

 

i just checked the uber shader in 2019.3.9f1 using Lux URP Essentials 7.4.1:
it works fine for me using the metallic workflow and sampling smoothness from metallic or albedo alpha.
which workflow do you use?
have you checked if your smoothness multiplier is not set to anything else but 1.0?

 

sorry, i have missed this.
cloth lighting nodes for shader graph are part of the package for a long time already. please have a look into the custom shader graph demo scene.

 

that is urp 10+ i guess. you should be able to already add this raising the shader trget to 4.5. and adding something loke #pragma multi_compile DOTS_INSTANCING.
i will add official support most likely once the deferred renderer is integrated.
