Ah, a closer look at your original screen capture shows the problem. Sorry for not seeing it earlier. You don't need to do any special mapping if you are using the billboards from the insert menu. So, either trash the current billboard and insert a new one or, in you shader tree, simply drag the multi channel mixer up onto the Flat Mapping branch - it should replace it. I just did the stock billboard with a movie here and everything works like it should. Mark
