I have a problem. I am rigging a character in LW and working on the legs. I have it set up so that I can drag a target for the foot on the Y axis, and get a nice bend at the knee and hip. I have adjusted the limits to get it to work pretty well within a decent range.. If I try to fully extend the leg, the joint snaps to an inverted position and I cant seem to get that smoothed out. Can someone give me some pointers?

Do you mean the joint of the knee? Did you set limits on the lower leg too?

Do you have a bend in the knee before you set up IK?

It only needs to be 1 degree or so bent, but this will give LW a preferential way to bend when solving the IK. This should stop most if not all the snapping.

yes, I made sure that they are slightly bent, it just seems that I hit a critical point of how far I can pull the foot out, and then in snaps into an inverted position.. any clues?
