since I'm on my bullshit:
If you want a hot tip for how to instantly improve any animation you make - open the spline editor and give your key frames some smooth transitions instead of linear ones
shit has mass and can't turn on a dime, and that's most likely what makes your animation look odd
for a bonus, make sure nothing is symmetric - twist a foot a few degrees, make it contact a frame later, slightly tweak the splines, etc.
Also, when I doubt, consult reference footage, animation has a ton of details you just miss out on if you do it from memory
@ChlorideCull oooh thanks! We tried to make a kink animation and it came out really janky.
How do you have a keyframe in the middle of a movement, though? Don't want to slow to a halt halfway through.
this post brought to you by seeing yet another mod for Sims that's perfect except for the fact that the animations are stilted and odd
