Spline Ik Bug?

[matt-gold]

hi all

I am having a problem. I have a number of whales, rigged with native max bones, moving along splines. at several points, the bones slowly move off the splines, and then pop back on. It as though they approach a threshhold, and then are popped back on the path once they reach it.

I can't find anywhere to control threshhold with splineIK, and changing my IK thresholds in Preferences has no effect. I've also tried changine and rotating the upnode. nothing seems to work. Help!

ps it seems to happen when the splines being used are longer, rather than shorter.

Hello Matt,

I think you could try to link your whale to a dummy, and make the dummy fallow the curve.
You then just make an "in-place" animation of your whale, making sure it loops ...
