We're attempting to add MaterialX support in Blender, and hitting this issue where ND_surface includes a EDF input. However , hdSt always fails with the following.
I've tried removing it from the output usda file, and it still seems to try and pick it up.
It looks like this is because the ND_standard_surface lofts up the EDF attribute and hdSt fails to deal with it. Instead of just ignoring it during the compile, it just outright fails.
Is there a workaround for this that anyone might know of in the meantime?
