Question Hybrid Renderer V2 + New Graph Shader error

Unity: Unity 2020.3.4f1 (64-bit)
Hybrid Renderer: Version 0.11.0-preview.42 - January 22, 2021
Shader graph: Version 10.4.0 - March 11, 2021
Universal RP: Version 10.4.0 - March 11, 2021

I'm getting the error below when I assign any newly created shader from Shader Graph to material to be used by Hybrid Renderer. The mesh is not drawn.

Code (CSharp):

1. A Hybrid Renderer V2 batch is using the shader "Shader Graphs/TestShader", but the shader is either not compatible with Hybrid Renderer V2, is missing the DOTS_INSTANCING_ON variant, or there is a problem with the DOTS_INSTANCING_ON variant.
2. UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

However, everything works when I assign the default shader. For example

Universal Render Pipeline/Unlit

Do I somehow need to tell Shader Graph that I'm going to use the shader in Hybrid Renderer?

I create a mesh entity in the code below

Code (CSharp):

1.  
2.             using var ecb = new EntityCommandBuffer(Allocator.Temp);
3.             var mesh = new Mesh();
4.             mesh.SetVertices(new[] { Vector3.zero, Vector3.back });
5.             mesh.SetIndices(new []{ 0, 1}, MeshTopology.Lines, 0);
6.             var material = Resources.Load<Material>("Materials/Test");    
7.             var lineEnt = ecb.CreateEntity();
8.             ecb.AddComponent(lineEnt, new Translation { Value = new float3(0) });
9.             ecb.AddComponent(lineEnt, new Rotation { Value = quaternion.identity });
10.             ecb.AddComponent(lineEnt, new Scale { Value = 1f });
11.             ecb.AddComponent(lineEnt, new LocalToWorld { Value = float4x4.identity });
12.             var desc = new RenderMeshDescription(mesh, material);
13.  
14.             RenderMeshUtility.AddComponents(lineEnt, ecb, desc);
15.  
16.             ecb.Playback(em);
17.  

Thanks.

 

I've seen the exact same error but the build of my project is complete unaffected. Try building your project, see if the log has anything special. If it does, you might need to rewrite the shader in HLSL but I seriously doubt it'll be a problem.

 

You need to downgrade to URP 10.3.2, that's the only workaround now.
Or you can use Lit shaders.

Unlit URP shaders have been broken in URP with Hybrid V2 for a while now.

See:

If you can, please vote on this issue on the tracker.

 

Can confirm. After downgrading the error disappeared.

Voted.

Thanks.
