Hi, I'm trying to output some message in backward pass in diffrast, Does the exmaple earth.py not propagate the gradient in rasterization stage? Because I missed all output messages in backward function.

Sorry, my mistake, I did not notice the example earth.py is used for optimizing texture. :anguished:
