Hi,
I'm still working away on this sort of stuff in the background. I've not posted anything about it because I've not made lots of progress until recently.
I'm hoping if I succeed to put a video together on this in about a months time and I'll release all my code.
There should be some nice blended animation and foot placement stuff in it. I've done the blend trees I just need to incorporate it into my overall game system then do the IK foot placement.
I've got a blend system that will blend and play:-
idle, walk/run, walk left/right, crouch walk/run, crouch left/right all at the same time depending on speed/angle/crouch factor.
