Good thread anon.
I've been doing some animations for my porn game using Honey Select 2.
HS2 definetely has more potential than I thought, but it also has some limitations when it comes to animating movements and stuff.
If I see some success with this project, I'm thinking on moving on to Blender, although it looks like the learning curve is pretty big, not just with animation but modeling and rigging too (I don't even know what rigging is but there's a ton of tutorials about it so it must be important)
