Hey, Poser MATs are non-translatable to Bryce. Second, Bryce imports Poser image maps, but they are adapted to Poser, so you have to change the ambience, the specularity, the bump and so on. Might be tedious, but it's simple and straightforward. Transmaps are no different than other image maps. So, no flat grey OBJ files. You want to tell me that Cinema accepts Poser textures without any need to change anything? I've got C4D 8 demo here which doesn't use the information in MTL, unlike Bryce, which asks me where are the image maps.
