well,..."big" is a good point :)
my first animation (just a Vicky with nothing else moving a little) of 10 seconds (192 frames) has the sweet size of 135Mb in avi.-format
:)
I guess the next thing to learn is: "How to reduce file size"  :)

However: It is big fun already just playing around a little, and see your characters "alive" !
So again: Thanks a lot
