I'm trying to do a PhotoView render of an assembly that has parts made of the same material (melamine) and the same appearance (white low gloss plastic). The problem is that when rendered the parts show up as grey, except for two drawers which show up white as they should. I have gone into each individual part and cleared its material AND appearance, made sure to apply the same material as before as well as the correct appearance (to the entire part, not just a face) and have done that for all parts. Yet this problem still persists. Attached is a screenshot of the rendered image and how the assembly looks in SW.
