[Released] Lux URP Essentials

Hello,
I add Lux Unlit Decal shader in Graphics>Always Include Shaders, and I got these errors
and if I dont add it, build is finishing without errors, but it wont be visible on mobile build,
what im doing wrong? unity 2019.3, luxURP 10.3.2 package, unity urp 10.3.2

Code (CSharp):

1.  
2. An asset is marked with HideFlags.DontSave but is included in the build:
3. Asset: 'Library/unity default resources'
4. Asset name: Hidden/InternalErrorShader
5. (You are probably referencing internal Unity data in your build.)
6. UnityEditor.EditorApplication:Internal_CallGlobalEventHandler ()
7.  
8. Building - Failed to write file: Temp/StagingArea/Data/Resources/unity_builtin_extra
9. UnityEditor.EditorApplication:Internal_CallGlobalEventHandler ()
10. Build completed with a result of 'Failed' in 81 seconds (80743 ms)
11. UnityEditor.EditorApplication:Internal_CallGlobalEventHandler ()
12. UnityEditor.BuildPlayerWindow+BuildMethodException: 4 errors
13.   at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (UnityEditor.BuildPlayerOptions options) [0x002ca] in <50f55621a2ca4f31a35283e2979a8bf5>:0

i haven't seen this before. but you may try to edit the decal shader.
open it and go to its very end. see if it points towards the "Hidden/InternalErrorShader".
if so remove that line and try again.

 

any feedback regarding the urp 12 preview?

 

Hi, does the lux URP essentials package work with the latest URP version? 10.5.1? (using unity 2020.3.11)

 

latest official one should be URP 11? but yes, 10 and 11 are supported.

 

URP 12 preview
i have been working on adjusting the shaders to latest beta 5 - which looks as if it has some massive drawbacks compared to beta 4: like screen spaced shadows in deferred being totally broken...
nevertheless I implemented some major changes like best-fit normals which will be supported by at least the uber shader.

Best-fit normals are useful in deferred rendering: The default quality of the GBuffer normals is far from being optimal (8bit per channel only) and will create a faceted look on sharp specular highlights.

So URP’s deferred renderer offers Accurate G-buffer Normals. Activating this feature however means that all normals on all materials will be first encoded to OctQuadEncoded ones during the GBuffer pass and then decoded for each deferred lighting pass – which produces some overhead (and breaks the terrain add pass…).​

You might have a lot of materials where low quality normals would just be fine as you have a strong normal map or low smoothness so artifacts are barely visible.​

Here best-fit normals come into play as you dedicatedly specify which material needs high quality normals and only use them there. Furthermore best-fit normals only need the encoding step, decoding is just the same as for regular written normals and virtually free.

So best-fit normals let you save a lot of computational power by adding the possibility to render high res normals only on selected objects/materials.​

URP low quality GBuffer normals. Note the pixelated or faceted look of the highlight.




Uber using best-fit Normals. Normals here still are not perfect and will show some noise. But in most cases they look way better than the standard normals.

 

Thanks! just making sure before purchasing.
BTW the asset looks great!

 

thanks!

 

I found some error.
Some paths of #include aren't correct.
They should under Grass.

Code (CSharp):

1. "Grass/Includes/Lux URP Grass ShadowCaster Pass.hlsl"

instead of

Code (CSharp):

1. "Includes/Lux URP Grass ShadowCaster Pass.hlsl"

 

damn!
thanks for reporting.

 

hmm, just had a quick look here and everything compiles fine (windows 10).

edit: most likey because you updated the existing installation. totally forgot about unity updating files due to their meta in place. i will reorganize the beta package.

 

preview for beta 5 is submitted. it should be available soon.

 

preview for beta 5 is available.

 

Hi lars, any guides on packing lux shaders into asset bundles? I found strange issues with lit extended shader:
One of my material uses the specular pipeline of the lit extended shader, and it all rendered correctly. But anohter material with metallic pipeline cannot sample the normal and metallic map.
Both materials are packed inside assetbundles and the bundles are all loaded on startup of the game. Any ideas?

 

not really as i have never worked with assetbundles.
i assume that the metallic and normal enabled shader variants got stripped off in the bundle for some reason. but i can't tell you how you can fix it, sorry.

explicit shadervariantcollections?

 

I tried to compile all variants for the shaders. But then I ran into this error:
invalid subscript 'instanceID' on line 86 of Lux URP Depth Only shader. It prevented me compiling all variants...

 

you can comment:
line 251: #pragma multi_compile_instancing
in case you use srp batcher (as instancing will not take place anyway).

 

Any updates on this?

 

not from my side. i never really got the point. and evem looking over it again it is quite difficult for me to understand the problem.
what caught my attention tho were the "hidden" parts like highlighted below.
you may try to exclude them using stencil and ZFail.

 

Hi, uh..
I'm having a lot of issues when importing the asset even in a completely blank project... I created a new project using the URP template and imported. It gives me a lot of shader errors..
I used the Package Manager > My Assets and downloaded the Lux URP Essentials from there. I even deleted the cached asset and made sure that it's the latest one.



@Edit
oh nvm.. I just saw the post above!

 

depending on the version of urp you have to import the corresponding package so urp 10 and 11 need these.

 

What I was trying to achieve was some way to create something that could work as telegraphed areas for abilities that could work with non-flat surfaces without having to use projectors. I couldn't get the hidden parts to not show but I might return to it and try again when I'm motivated again, haha.

 

It seems like we need to get what stencil shader with two passes does but in urp, but urp calls only the first pass by design, so RenderObjects have to be used instead for additional passes to work.

Here is a forum post with some discussion:
- https://forum.unity.com/threads/intersection-shader-cull-front-minus-cull-back.536812/

The answer on it uses three passes, but the one below uses 2:
- http://answers.unity.com/answers/1487831/view.html

However as of recently answers.unity don't work because Unity needs to extend their domain/service license or whatever..., so here is the code from the 2 pass shader:

Code (CSharp):

1. Shader "Unlit/highlightVolume"
2. {
3.     Properties
4.     {
5.         _Color("Color", Color) = (1,1,1,.2)
6.     }
7.     SubShader
8.     {
9.         Tags{ "Queue" = "Transparent" "RenderType" = "Transparent" }
10.         Pass
11.         {
12.             Stencil
13.             {
14.                 Ref 172
15.                 Comp Always
16.                 Pass Replace
17.                 ZFail Zero
18.             }
19.             Blend Zero One
20.             Cull Front
21.             ZTest  GEqual

38.             {
39.                 float4 vertex : POSITION;
40.             };
41.             struct v2f
42.             {
43.                 float4 vertex : SV_POSITION;
44.             };
45.             v2f vert(appdata v)
46.             {
47.                 v2f o;
48.                 o.vertex = UnityObjectToClipPos(v.vertex);
49.                 return o;
50.             }
51.             fixed4 frag(v2f i) : SV_Target
52.             {
53.                 return _Color;
54.             }
55.             ENDCG
56.         }//end color pass
57.     }
58. }
59.  

 

Hi, my current unity version is at 2020.3.14f1 and the URP doesnt go down to 10.3.2, only to 10.5.0 (and up to 10.6, so I can't jump to 11). And I have been getting errors since importing the files as well as the decals not working at all. What should I do?

 

there is a package for urp 11 as well.

 

any reason why decals and screenspace fog are showing through these materials? my guess is that these materials are not writing to the depth texture.

 

Hi! Is there a way to set up the toon shader for that kind of shadowing? https://blender.stackexchange.com/q...ipple-shading-be-replicated-in-blender/144160

 

not at the moment...

 

So im on URP 10.4 and I have the LUX 10.3.2 package installed. Only the Skin shader is failing to compile with this error:
undeclared identifier 'LuxURPSkinFragmentPBR'

Should i try to install the LUX URP 11 package? or will that break other things?

 

strange. this means that the lighting function is not defined?!
try to reimport the shader first.

 

Yeah, Reimport worked. Strange. On another note, do these shaders write to the depth texture? For some reason my post process fog is not getting its depth.

 

the skin shader? it writes to depth, yes. but use the frame debugger to be sure.

 

Maybe this is the issue? it looks like its not being written into the Depth prepass?

 

it is the depth normal prepass. do you have the right package installed?

 

Hi, what are the settings I need to do for toon water something stylized?

 

I reimported the package and it looks ok now. Not sure why it keeps doing that lol.

 

These shaders are great thanks. By the way, maybe in a future version, an option to use alpha dithering with alpha clipping on the geometry queue instead of transparency would be awesome.

 

for things like decals and particles I mean...

 

i guess you will need proper textures for foam and normals.

 

I have one question. Would it make sense to add parallax mapping to mesh terrain shader. Mesh terrain shader should be faster than terrain shader and normal mapping doesn't look as good in VR. I haven't tried but parallax mapping should give convincing look in VR. With mesh terrain parallax mapping we would get faster rendering and more convincing look compared to just normal mapping (I hope).

Thanks!

 

the mesh terrain shader originally was written for a mobile project. so it focused on limited resources.
the shader itself should be a bit faster than the terrain shader. the big difference however is the mesh (uvs, overhangs) compared to a unity terrain (top down projection, height map based) which allows e.g. less or optimized vertex density and lets you create complex shapes.
on the other hand it is a bit demanding as you have to model and texture the terrain most likely outside of unity and loose features such as grass.

depends... in case you have a "huge" terrain you would have to slice it into smaller chunks so that the cpu can do a good culling job.

but in order to het you started: with a few tweaks you should be able to use the terrain shader on a mesh:
- comment all the [HideInInspector] attributes
- then add:
_DiffuseRemapScale0 ("DiffuseRemapScale0", Color) = (1,1,1,1)
_DiffuseRemapScale1 ("DiffuseRemapScale1", Color) = (1,1,1,1)
_DiffuseRemapScale2 ("DiffuseRemapScale2", Color) = (1,1,1,1)
_DiffuseRemapScale3 ("DiffuseRemapScale3", Color) = (1,1,1,1)
to the properties.
this will still give you a simple top down projection but if you are fine with the result performance wise you can change the uvs in the next step.

 

Thank you, i will definitely try it out. You are freakin' awesome!

 

Just to let you know. When I wanted to try "Lux URP/Terrain/Lit" shader with single pass instanced it complained and to fix it update ~\Assets\Lux URP Essentials\Shaders\Terrain\Includes\TerrainLitPasses.hlsl at the very bottom, it needs to look something like this

Code (HLSL):

1. half4 DepthOnlyFragment(Varyings IN) : SV_TARGET {
2.             UNITY_SETUP_STEREO_EYE_INDEX_POST_VERTEX(IN);
3.             return 0;
4.         }

 

No, they are just shaders no texture needed. I was wondering if the toon shader part will be able to make a scene like this

 

latest should fix a bunch of vr related issues. thanks for reporting!

 

maybe. like the shaders used in the screen shot you have posted lux urp essentials toon comes with its own lighting function. which may allow you to create a look just like this...

 

Hi I just installed version 1.38.0 inside Unity 2019.3.0f6 and I'm getting a bunch of errors like this one.

error in 'Lux LWRP/Projection/Decal Unlit': failed to open source file: 'Packages/com.unity.render-pipelines.lightweight/ShaderLibrary/Core.hlsl' at line 88 (on d3d11)

 

just reimport the shaders. unity has massive problems here...

 

Hi. I'm using URP 10.7.0 on Unity 2020.3.19f1.
I tried importing LuxURPEssentials_URP_10.3.2 and LuxURPEssentials_URP_11 packages.
Both generate errors :

Assets\Lux URP Essentials\Scripts\Editor\LitExtendedShader.cs(4,29): error CS0234: The type or namespace name 'Universal' does not exist in the namespace 'UnityEditor.Rendering' (are you missing an assembly reference?)

The project was initially made within Builtin, converted to URP. Would you know where the issue is ? Thanks.

 

crazy, that is the name space which is also used by e.g. the BaseShaderGUI.cs inside the urp 11 package. so it should exist...
