IK Spline Handle tool???

Yes, skin and weight first. Then add Ik, and use a locator for each of the elbows and knees to make a pole vector constraint to each IK. Then, and this is important, parent the locator under the IK chain. Hope that helps you.

Why is it important to parent the locator at the end of the IK chain? What benifit does it have? Please elaborate.

And why does the, "Spline IK Handle Tool" make the skeleton pop to a slightly different possition? The, "IK Handle Tool" doesn't!

What I think it does is average the points positions when you create a splineIK. (sorry, I answered you question on the 2nd post)

I have also had the IK move my skeleton before when making arms and legs, but it usually isnt a problem.

My best advice for you is just to try the locator thing I told you. Make it really simple for yourself. Open a new scene and create a couple of bones (no geometry, you dont need it). Make an IK handle, then a locator where you want the elbow or knee to point. Create the pole vector constraint first, then parent the locator to the IK handle. Now just grab the IK handle and move it around, you'll see the locator move with it, in a relative way. Then you can animate the locator seperately. Try it out, and let me know what you think.

For the splineIK you can take the points on the curve and make clusters with them. This will give you a better control over the spline, it works much in the same way as the locator mentioned above.

I agree with you for setting pole verctor constaraints for the elbows and knees. I have been using the Spline Ik tool for the spine.

It makes sense to parent the pole vector constraints to the IK Handles. I thought you meant parent them to the end of the IK chain.

Thanks for clearing that up.

hi,
the ik spline move your joints because when the curve is created there is some approximations to try to have the shape of the curve to mimic the shape of your joints, if you want to minimize that, try to set auto simplify curve to 3 or 4 or try to uncheck auto simplify curve. the drawback is that more cv you have on your curve, more you`ll have to create clusters to control your curve...

excuse me for my english :D
