Question DOTS, Handwritten CG shader SRP Batcher

Hi,

I've ported from an older version of ECS where hybrid still worked on built-in pipeline. Now I run on graphics 1.0.0-pre.15 with URP.

I'm mainly using this shader:

Code (CSharp):

1. Shader "Standard Unlit"
2. {
3.     Properties
4.     {
5.         _MainTex ("Diffuse", 2D) = "white" {}
6.         _LightmapTex("Lightmap", 2D) = "white" {}
7.         _OcclusionTex("Occlusion", 2D) = "white" {}
8.         _NormalmapTex("Normalmap", 2D) = "bump" {}
9.         _SpecularmapTex("Specularmap", 2D) = "white" {}
10.  
11.         _Cube("Reflection Map", Cube) = "" {}
12.  
13.         [PerRendererData] _Color ("Color", Color) = (1,1,1,1)
14.         [PerRendererData] _LightMapColor("__LightMapColor", Color) = (1, 1, 1, 1)
15.        
16.         [PerRendererData] _ShadingRootPosition("__ShadingRootPosition", Vector) = (1.0, 1.0, 1.0)
17.         [PerRendererData] _ShadingDirection("__ShadingDirection", Vector) = (1.0, 1.0, 1.0)
18.         [PerRendererData] _ShadingIntensity("__ShadingIntensity", float) = 1000
19.         [PerRendererData] _MaxShadingColor("__MaxShadingColor", Color) = (1, 1, 1, 1)
20.         [PerRendererData] _MinShadingColor("__MinShadingColor", Color) = (0.3, 0.3, 0.3, 1)
21.         _SpecularColor("SpecularColor", Color) = (1, 1, 1, 1)
22.         _Cutoff("Alpha Cutoff", Range(0.0, 1.0)) = 0.5
23.         _TopLightColor("Top Light Color", Color) = (1, 1, 1, 1)
24.         _CenterLightColor("Center Light Color", Color) = (0.95, 0.95, 0.95, 0.95)
25.         _BottomLightColor("Bottom Light Color", Color) = (0.5, 0.5, 0.5, 0.5)
26.  
27.         _HasReflection("__HasReflection", Range(0,1)) = 0
28.  
29.         [HideInInspector] _Mode("__mode", Float) = 0.0
30.         [HideInInspector] _SrcBlend("__src", Float) = 1.0
31.         [HideInInspector] _DstBlend("__dst", Float) = 0.0
32.         [HideInInspector] _ZWrite("__zw", Float) = 1.0
33.         [HideInInspector][Enum(Off,0,Front,1,Back,2)] _Cull ("__cull", Int) = 2
34.     }
35.     SubShader
36.     {
37.         Tags{ "LightMode" = "UniversalForward" }
38.         Blend [_SrcBlend] [_DstBlend]
39.         ZWrite [_ZWrite]
40.         Cull [_Cull]
41.  
42.         Pass
43.         {
44.             CGPROGRAM
45.             #pragma multi_compile __ _HAS_LIGHTMAP
46.             #pragma multi_compile __ _HAS_CUTOFF
47.             #pragma multi_compile __ _HAS_NORMALMAP
48.             #pragma multi_compile _NO_REFLECTION _REFLECTION_FROM_COLOR _REFLECTION_FROM_MAP
49.             #pragma multi_compile __ _HAS_SHADING
50.             #pragma multi_compile __ _HAS_LIGHTMAP_COLOR
51.             #pragma multi_compile __ _HAS_OCCLUSION
52.             #pragma multi_compile_instancing
53.  
54.             #pragma target 3.0
55.             #pragma vertex vert
56.             #pragma fragment frag          
57.             #include "StandardUnlitShaderCore.cginc"
58.                        
59.             ENDCG
60.         }      
61.     }
62.  
63.     CustomEditor "StandardUnlitShaderGui"
64. }

I've managed to get it to work with URP but not with DOTS. Do I have any chance to create something similar with ShaderGraph or manually that would be compatible with UNITY_DOTS_INSTANCING and SRP Batcher?

Could you guys send me in the right direction regarding the documentation/samples for handwritten shaders compatible with SRP? Thank you all!

 

Thanks for sharing this.
I've managed to get it SRP-compatible and DOTS-compatible.


I have the DOTS_INSTANCING_ON, couldn't find more info on this. What exactly means: "Missing DOTS_INSTANCING_ON variant"?
