Hello Memaci, The best way to handle this within Carrara is by useing the objects tray. As you complete an object, drag it into the objects tray so you can simply drag into your final scene later. (I've got folders for each project.) This technique prevents corruption of shaders (shaders with the same name simply occur as "Shader Name"1, "Shader Name" 2 etc. Also, it prevents cameras, render sizes, light intensities and other things from changing like they do when you import a Carrara or RDS file/object into your working scene. Additionally, should the final scene become corrupted you still have access to the components separately. Mark www.MarkBremmer.com
