What is IK & FK?

posted to: VonnBots Rig Demo

You mention them in this video, but I don't remember going through forward/inverse kinematics. Will that be addressed in a future lesson?

    This will explain everything. (it is a video I made before working for CGC)

    Thanks, that’s really helpful. I noticed with the Vonn bots that the legs have both IK and FK that you can toggle with that slider. Do you have to choose one or can you switch between them during an animation action?

  • Wayne Dixon replied

    You can switch during an animation (I think I do that in the Rivet box lift - can't recall off the top of my head)

    But it's usually easier to stay in the 1 mode for the entire shot.  Well that is generally the case, but there's always times when switching is the easiest thing to do.  And you probably won't switch the legs very much at all (just the arms mostly)
