- set_frame() --> frame_set() - set_context_pointer() --> context_pointer_set() material adding works for curves and metaballs, new function to remove materials. materials.link() didnt well fit how this is used elsewhere - order matters - it can be linked more than once. - remove(material), isnt that useful since you need to manage indicies. ... use list style functions instead. materials.append(mat) / materials.pop(index)
