I've only used alpha in numbered png sequences, that works fine. I haven't tried the new version using tif sequences yet, the old one inversed the alpha, hence the use of png.

Wax is supposed to support alpha in AVIs, but as Vue Pro won't render an animation with alpha - it saves the channel in a separate, monochrome, AVI - and Poser 5 just seems to crash if I render to AVI, I don't really have a source of 32 bit AVI to test it with.

This latest version (2.0c) has got rid of all the bugs I'd come across, although it does still seem to have the bizarre "feature" that you import a numbered sequence by selecting the first file, then control (NOT shift) selecting the last, fine when you get used to it, but not exactly intuitive! I'd recommend giving it another try.
