There seem to be endless combinations to use!!! Did you look at the PSP forum question there? Someone has left some images they've done in that, and said they render with anti-alias on and over black, (obviously not firefly) save as a TIFF then get rid of the background in PSP via the load alpha channel method. His renders are perfect! I've asked if he could upload a screen-shot of his render screen. Meanwhile, let's keep in touch over this and if either of us discovers the answer, we can let one another know... (I've never used the Lassoo seclect tool for this particular purpose btw. Interesting option...)

Is the light at the end of the tunnel my way out, or is it an oncoming train just about to make me extinct?
