Gary, thanks for a timely response. Funny, though, when I import gif w/transparent background, it moves nicely into CTA, but the animation does not play (???). And the png...is that not only for still image?
I suspect I must have a video editor that will mask such as your product or Reallusion's Pop Video Converter. I was hoping this capability was somehow "built in to" your Xara 3D. As you can imagine, Xara 3D has a lot (!) of potential together with CTA as well as the other Reallusion programs.
