Can you try replacing the line

faces = faces.type(torch.int32)

with

faces = faces.type(torch.int64)

?

[sunshineywz123]

.type(torch.int64)

when i render, get error:image_renderer(meshes_to_render, cameras=cameras) *** RuntimeError: expected scalar type Float but found Long

Can you paste your current code? The verts need to be float32, the faces int64
