    I'm wondering if it's currently possible to support the Single Pass Instanced rendering path for XR when using the new Mesh API (eg: https://docs.unity.cn/ScriptReference/Mesh.SetVertexBufferData.html). I know how to make my shaders support instancing but I'm not sure how (or even if it's currently possible) to have Unity pass the correct instanceID to my custom vertex layout. There doesn't appear to be any VertexAttribute enum for InstanceID yet so I can't see how Unity could auto-magic this for me.

    Is instancing not supported for the new Mesh API yet?
