i build ik rigging for most of my heavy animating, especially big things, as you all know.
heres a little example i whipped up using my big robot from unfinished static scrubber.
using only simple beziers for feet movement and sine oscillations for the arms and body, you can do alot if you make a well rigged character, and you dont have to be a great animator. this took me 5 minutes to animate and the result is pretty good.
if i were able to code id make a puppet editor using my techniques for construct, but since i cant ill probably make a nice tutorial for everyone showing a whole bunch of my cool little techniques ive figured out.
(alot of stuff is drag and dropable, play around
