How do you make a knee target in Blender? For instance, an Empty that the knee will always point at. I've been trying a myriad of things on my own, none of which have worked.
I've been searching all around for an answer to this. I made an Elysiun post, I asked on both the blender and blendercoders IRC channels. So far no solution. It seems ridiculous that there would be no way to do this in Blender, because it's essential to building a controllable rig.
I figured out a way to do it. The solution .blend file is posted on the Elysiun thread.
hdd: It's not as simple or intuitive as switching to a Locked Track constraint. I had tried that already. Getting a properly functioning knee target in Blender is actually fairly involved. I have a feeling I'm the first person to have done it... all of the example rigs people linked to had faulty knee targets, with the same problems I was trying to get rid of.
The only problem with my solution is that it can't be done entirely inside the armature object, so (I believe) that means you can't really use it with the actions editor or NLA system. But the rig behaves exactly as it should.
Please go to the Elysiun thread I linked to above for further discussion. Please do not reply here--I'd rather keep it all in one place.
So please answer. We don't want to distract Ton from project Orange, do we?
