I thought I would note something about the problems of saving DSON imported figures with conforming items. As a rule, very strange things happen if you try to save a figure with conforming items back to the library as a CR2. I have had more success by saving them as a scene file instead, either exported or using the scene folder on the library panel - you'll want to delete the lights before saving and then relight by clicking on the double tick option on the library to add to scene instead of to replace it.
