> Hi brecht, shi->flippednor is now forced to zero it seems, but it is still used in a few places (volume render, to determine if you're looking at the inside of a volume) and also in geometry node front/back. Is it safe to just replace these with a dot product, or was the normal flipping code more complex than that?
The normal flipping is now done in shade_input_set_normals, calling
shade_input_flip_normals, which will set shi->flippednor.
