Graphics.DrawProcedural + Surface shader = reflection probes don't work. please help

Unity Engine

Hi,

I use compute shaders to generate geometry.
I use Graphics.DrawProcedural to render geometry.

material.SetPass(0);
Graphics.DrawProcedural(MeshTopology.Triangles, _count, 1)

then i wrote my Surface shader to render surface of the geometry. It works but it doesn’t get the current reflection probe! It should work automatically coz its a surface shader.
How can I force it to use the current reflection probe?

P/s I’m turning off Mesh Renderer on the game object because it renders other things anyways.

Transparent Objects (Standard Shader) not rendering in front of Opaque Objects (Custom Shader)

I’ve been really struggling with this recently, and I cannot make shadows/environment lighting work either. Do you have an example to share?

Basically, if there was an example somewhere of using StructuredBuffers of vertices, normals, uvs, etc… in a surface shader to draw properly lit/shaded geometry drawn with Graphics.DrawProcedural, it would save my life

Some clues:
procedural meshes (function Graphics.DrawMeshInstancedIndirect ) with surface shader:

@Luckymouse Any luck on this one. I have having the same issue in 2020.3
