YES YES YES Max 5 IK/FK Switch

YES YES YES Max 5 IK/FK Switch

I played around with max 5 animation to test the FK/IK switching and it works great !!!
I didn't even have to touch the curve/track view editor...

But another problem appear... the pivot bone does some stupid strange rotation sometimes... I looked in the curve/track view editor there...but it didn't make sense @:(

Didn't animate the swirvel angle since it is a ik/fk test, so arm/leg flipping might appear!!

Keep in mind it's just a test... [20 sec. Divx 1.95 mb]

Comments are welcome as usual
Anyone who know about the rotation problem ?

Might be a bit late but here's the difference:

FK: traditional style animation in which all joint rotations and tranlations are manually keyed. No end effectors. Useful for getting really good weight and timing, especially on upper limbs.

IK: this is what you already know as single chain and rotate plane solvers. The chain of bones is controlled by and end effector. Good for when you have to make things stick to other things (feet to floor, etc), but otherwise a little limiting.

hope this helps

Here's a link with some info about IK on MAX. Max 5 has a better IK setup, so this tutorial might not be useful. Anyway:

Yes. You can either key ik on and off, or there's a useful little skeleton rig on that allows you to blend between the two (I think it rigs two copies of the skeleton up).

one large problem that i see with that animation is that the collar bones dont move at all. if they dont move then you dont need them right?
