Ah, that is true. It's probably not a top priority at this point anyway XD Maybe one way of circumventing it could be only allow larger meshes from certain programs, i.e. imported from MagicaVoxel only or something. Idk-- again, it's probably a low priority :P
Ah, thank you! Yeah, I noticed it saved a lot, even if I changed only one frame, and that seemed a little inefficient so I thought I'd mention it. It might speed the whole saving process up and such :)
I'm glad I found it too! It seems like a great program with a lot of potential!
