I rigged the character a while ago, but I generally remember a quick learning curve regarding a couple things that kept the auto rig from happening. Once it did, it just worked beautifully. Very easy to work with, though my character was only dancing in place, so not sure how difficult it is to walk cycle or otherwise stick feet to ground or other objects.
That being said, my only previous experience was experimenting with AE 2d auto-rigs. I actually moved to C4d for the character because it became rapidly apparent that character movement is just much easier to deal with in 3d even if it’s being rendered flat. I may give joystics and sliders a go at some point just out of curiosity for the unique approach, but overall, I don’t see myself trying to do 2d character animation again unless it’s just goofy non rigged bends and such. Too much work for too many limitations. Much more liberating in 3d.
Good experience overall, but not much to compare it to. I was able to get the dance moves in relatively easily with no prior 3d rigging experience.
