    Hi there,

    I am trying to use SRP with Pure ECS. I am building custom shaders in Shader Graph which require per-instance variables to be rendered properly. How can I achieve this? If not possible yet, please let me know how big of a priority it is. If I need to switch back to Classic rendering I will.

    Thanks
    James

    Hi,

    Assuming you are talking about `BatchRendererGroup`, I'm afraid this will not work (at least for now). This only supports Model matrices per instance and doesn't support arbitrary per-instance data. Core Graphics team is working on expanding this but I'm afraid I cant offer any real information or timelines.

    When we have the underlying implementation in place, Shader Graph will then need to look at supporting generation of arbitrary constant buffers.

    That's great to know! I'll stick with classic render pipeline for now. Thanks!

    How about now?

    There is a "Hybrid Instanced (Experimental)" checkbox under Color and Vector1 in the Blackboard. Is that it?

    Can you please give a feedback.

    Any update on this in 2022? I have a Shader Graph material that I'd like to support GPU instancing but I couldn't find much info out there about it.

    The InstanceID node can't even work properly in 2022.2... RenderMeshPrimitives can set the
    SV_InstanceID attribute in traditional shader file while InstanceID node in Shader Graph always return 0.
