Mecanim Foot Sway

Hi guys,

I've had this problem for a long time and I cannot for the life of me figure it out. I'm really at the end of my tether.

Every time I do an idle animation with hip movement in it and bring it in to unity (anim compression switched off, tried all combinations of root motion baking etc) the feet slide around.

I know that theres nothing holding the feet in place, but on a baked anim they should be perfectly countering the animation of the hips thus giving the illusion they are held in place but this just isn't happening.

I work as an animator in the games industry so it's not like I don't understand what's going on I just cant get it to work as I feel it should be.

Do I need some kind of root bone that's on the floor that has no Y axis animation on it or something? I thought maybe that was the case but when I look at other peoples rigs they don't seem to have this.

Cheers.

 

For anyone else looking for a solution to this after about 5 hours I've just found the ridiculously stupid solution.

In mecanim click on the anim state and tick the "Foot IK" box in the inspector.
