Blender 2.55 Shapekey driven by a bone with Constraint

Support Animation and Rigging
1

Hi there!

I have an IK/FK leg-rig. And I set up some shapekeys to have a nice knee deformation… (just a test for later on --> shoulders, eyes, etc).
It al works fine, and my shapekeys are perfectly driven by the bones…
UNTILL!!!:
I started to use the IK-rig. Somehow, with the IK-constraint on my drivers (the calf, for example) It just stop with driven my shapekeys.

I tested it in blender 2.49 and then it works fine, the only problem with blender 2.49 is that it can’t show two shapekeys at the same thime… (I mean, I see the nice deformation on the left knee, but not on the right. And also when i activate my right knee, it doesn’t show it’s left knee-shapekey.)

So I’m stuck :slight_smile:

I hope someone could help me ^^

thank you!
