Ok we should establish a rule here------> Please dont post , "you need to but a $3000 mocap suit"...We know this is the best option, just trying to work out ways around MOCAP AI issues, and find solutions.
.. Ive spent nearly 5k on computer and x2 versions of reallusion software (ic7+cc3 plus ic8+cc4 plus plug ins). so im broke and having to pay for loans on said purchases!!!... 3k is about 5 years away (*sniff*)

Just wondering if on the skeleton you can kill the feet to stop them from moving? 
How could you combat shakey limbs? limbs twisting? Usually twists on torso, The legs have odd twists as well.

I find it just a constant fight. Wondering if there are any Advanced tutorials out there on maybe using the curves? setting linear keyframes?.
I always find if you remove the keyframes the motion still moves, its just a constant battle and would love to know if there are fixes for these issues im not too familiar with.
