no one has been smart enough to write one yet. :biggrin:

would it work to do the V4 animation as blue or green screen and then make that blue or green as your transparent color ? What program are you using to do your video editing?

I haven't done animation in a long time but if I remember correctly, you can select colors to make transparent in the video editing program...maybe not all of them, but then do as you suggested, layer that resulting sequence over the time lapse.
