Any suggestion about rendering transparent part?

[XiongFenghhh]

Hello, I have a model with pbr mat which has transparent part ，but I don't know how to render it correctly. I got the basecolor of the transparent part instead of the color behind it. Is there a way to render it correctly?

@XiongFenghhh , If you are using nvdiffrast, you could use nvdiffrast.torch.DepthPeeler

Thank you for your suggestion, I got the desired render result based on the nvdiffrast document. However, according to the doc, the hyperparameter "num_layers" need to be set. Is there a way to automatically set it？ or does it currently only support manual settings？

with nvdiffrast.torch.DepthPeeler(glctx, pos, tri, resolution) as peeler:
  for i in range(num_layers):
    rast, rast_db = peeler.rasterize_next_layer()
    (process or store the results)

I set num_layers to a safe value.
