Is string processing in PBR shaders inefficient? I was told this kills arnold Arnold, but I wasn't sure about Mantra. For example, would it be bad to get my diffuse color map from a snippet:
texture_path = s@mtl_dir + “/” + s@asset_name“ + ”.rat";
Where both mtl_dir and asset_name are primitive/detail attributes?
