I've had no problems with animations in Poser 5, although I still do big things with multiple figures on my more powerful Mac with P4-Propack (pending P5Mac). But then I ALWAYS render as a series of large images. That way I can render once, and go back and reuse anything as stills and in another format or other projects. Save as .tif files and you get an alpha channel, if you want to use it for bluescreen over other images or video. I also use this to do batch rendering of still images - by setting them up as frames of an animation and let them happily render away unattended. HTH, Elisa/gryffnn
