I would like to start by saying that I did several searches for this first.
I’m making a mech for my current project, and I decided to test a simple walkcycle in the GE. I used IK bones, and I was (am) under the impression that they cause problems. Sure enough, my game worked fine until I hit escape, and then it crashed. I says to myself, I says, “maybe I should bake the action”, so I did, and removed the IK constraint.
Yaay, the game doesn’t crash any more. Oh, wait, baking the animation did absolutely nothing but add more IPOs; the IK bone moves, and the legs stay solidly in one place.
Unfortunately, I cannot post a .blend thanks to dial-up and working on an offline computer.
Many thanks in advance to all who help.
 oh, and I tested this oth on 2.42 and on one of the 2.43 RC’s (I think it’s the most recent one…)
