Cut Out Animation files supersized

I was making an animationtest this week and got a cut out Toon Boom file with just one character. The rigging was already done and with only 1 frame and 2 riggings of a character, the file size was already 3.9 GB.
When I finished the test that was 330 frames big, the filesize of the project became 20 GB!
I must say the elements folder was really confusing for me too.

Is it normal that when you work with cut out animation in Toon Boom, the files get huge and you need a supercomputer to be able to work with it? Or did something already go wrong in the rigging department that I didn’t do?

Thx! :slight_smile:
