How to render a texture with transpareny? I have a texture with transpareny defined in 4th channel, but when i render it in nvdiffrast it don't blend the color accross depth.

Nvdiffrast doesn't support automatic blending, but you can render the mesh layer by layer using depth peeling. You'll have to implement the blending yourself in PyTorch in this case. For reference, see the render_mesh function in nvdiffmodeling project.
