Use GL class to load projection matrix to render mesh in LateUpdate()

For some reason, I HAVE TO render things in a script, but i can’t do it

I called PushMatrix (),LoadProjectionMatrix(), but it doesn’t feel it’s working. It seems using the matrix from last camera(eq: editor scene view camera). Are these function locked unless in LaterUpdate? What should i do to load projection matrix and render mesh in script, not a working Camera or MeshRenderer?

it seems Graphics.DrawMeshNow use its own camera matrix. I end up using GL.Begin() / GL.End() way to render the whole mesh
