Question URP shader warning: Material property is found in another cbuffer than "UnityPerMaterial"

I wanted to create a custom simple URP shader (Unlit Transparent shader) for my 2D game and enable GPU-Instancing on that shader, so i followed the docs here. But Unity is giving this weird warning:




I saw on Unity blogs that this is an SRP batcher issue,

1- How can i fix this warning and still have GPU Instancing working on this shader?

2- Can i have GPU Instancing and SRP Batcher together?

 

Did u manage to solve the problem?

 

Hi! Im getting the exact same problem. I have no idea how to fix this. Any help would be very welcome

 

Do you know how to solve it? *-*

 

I had the same problem. The solution for me was to create a CBUFFER. I just copied the code from here (search for CBUFFER):
https://docs.unity3d.com/Packages/c...manual/writing-shaders-urp-unlit-texture.html

And the SRP Batcher Manual also says that this is required (Section "Shader compatibility"):
https://docs.unity3d.com/Manual/SRPBatcher.html

 

when i remove the code in red frame, the warning was disappear and srp batcher was compatible, but my custom shader must have properties region, I dont know how to solve that.

 

To solve this I added all floats of the shader inside a CBUFFER_START

Code (HLSL):

1.    Pass
2.         {
3.             Tags { "LightMode"="UniversalForward" }
4.            
5.             HLSLPROGRAM
6.             #pragma vertex vert
7.             #pragma fragment frag
8.  
9.             #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Core.hlsl"
10.             #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Lighting.hlsl"
11.                  
12.             sampler2D _MainTex;
13.             sampler2D _tintMask;
14.            
15.             CBUFFER_START(UnityPerMaterial)
16.             float4 _MainTex_ST;
17.             float4 _tintMask_ST;
18.             float _specularSize;
19.             CBUFFER_END
