Advanced Clay Render

Make it possible to exclude certain material types and properties from being replaced by clay, for example glass, null and light emission.

Code could be something like this:

exclude = {"glass", "archglass", "roughglass", "null"}
if clay:
    for key in props.GetAllNamesRE(r"scene\.materials\.[0-9a-zA-Z_\-]+\.type"):
        mat_type = props.Get(key).GetString()
        if mat_type not in exclude:
            props.Set(pyluxcore.Property(key, "matte"))
            props.Set(pyluxcore.Property(key.rsplit(".", 1)[0] + ".kd", [0.1, 0.5, 0.5]))
