This is the second in a series of four Introductory Video tutorials.
This one looks at using IK Boost in a more practical sense, that is, creating the beginnings of a walk cycle.
This provides the first opportunity to see IK Boost as an animation system and some of the built-in animation tools.
(Sorry this one is a little ropey, hopefully I’ll get a chance to improve it soon)

Just gets better and better!
One aspect of IKB that I would really like to get to grips with is the use of the mirroring function. Particualrly with walk cycles. Can IKB Mirror over poses form limb to limb? I have tried (and failed) to get this working. Your ,ovies shows how much time gets wasted flopping poses from left to right limbs. It would be great to do this for creating speedy on the spot walk loops.
Any thoughts?
May 12th, 2006, at 3:53 pm #yeah, I have exactly the same difficulty.
The only way it works for me is by Mirroring Chains, say from Left Leg to right leg. It need to work for the whole RIG. I think this would be simple to do as an LScript out side IKB for starters. I also asked about this on Splinecage but didnt get any biters.
Actually, when I started looking at IKB, this was the first thing I that seemed wrong, so I mailed tech-support… the responding silence was deafening… one of the reasons for ikboost.com…
Anyway, back on topic…
Since this does seem to work on L and R chains… there might be ways to hack a quick fix (until NT add decent functionality).
I have tried making RIGs that have two spines and two hips, and that’ll work but its a bit of overkill for this problem.
It may work just by dupliating the whole hierarchy, then flipping and copying across a temporary dummy model…
The last thing I’d say is that as the RIG improves more and more, it will be ten times faster getting to poses (the RIG from the Walk video is twice as awkward as the RIG from Video 3) and quick-flipping will become less of a requirement, even for quick background stuff (though it will always be needed for sure)
Whew!

On the one hand I’m kinda ticked! I told Larry, and I meant it, that he didn’t REALLLLLY explain what IKB was, in terms that I could understand it. I”ve missed out on this tool all of this time because I couldn’t appreciate the sheer power of it. Your tuts have completely blown me away!!! I love Larry, he’s my mentor and teacher, but on this one, I must say, I’ll be anxiously looking forward to everything else that comes down the pike concerning this one, and I hope some of the other “issues” can be quickly resolved, (like matching feet and/or arm movements, etc.) because this is waaaaaaaaaaaayy cool!

To my shame, I didn’t follow up on it.
The script is on his excellent site:

If I had time, it test it!

Hi - I have been using your rig system and it is great. I have tried to use motion mixer with it to extend or repeat a basic walk cycle and every time I save the scene and then open it the charcaters legs strech out going strait down and IK booster does not work any more. Am I saving the motion mixer file wrong? Is there a better way to get the walk cycle and all the bones to repeact so I can walk my characte acroos the yeard? One las question I tried to parent an object to the hand of my character and it does not work. I tried to parent the object to bone 18 in his hand, and it flies all over the place. What did I do wrong? I so look forward to any new posting you or your fans make. Thank You
