Thank you so much for your replies. I have narrowed down the problem. It seems to only happen when the 3D object has a material that is transparent. I've designed a series of plexi bonnets for a display system. Every time I generate a 3D view, cut and paste onto the 2D surface this happens, but only to the materials that are transparent. (see attachment) I've gone back to previous files and can copy and paste any transparent image with no problem. I've copied the slabs/objects from previous file and tried it in the latest version and have the same problem. I've even dumped the preferences in case the file is corrupted, still the same results.
I am working with the internal engine, not the Open GDL. I need to adjust the fills of the 3D image once in the 2D window, so an image file wouldn't work.
Thanks again for your help.
