Hello,

Does anyone have ever used a script named "AS_TREADS" that builds treads from an object and a path curve ?

I'm experiencing problems with it : Some parts of my treads flip the wrong side (because of the curve topology - control points that aren't at the same side makes it flip)

Any idea to fix that ?

Thanks

yeah I have used it and I had the same thing, luckily for me it happened on a piece of the track that was out of sight, I'm not sure how you fix it I'm afraid, I think it's a gimbal lock issue. Email the support guys and ask them.

Ok, tried a simple animation snapshot and it does the same : flips some parts

See what it does when i create an animation snapshot...weird

I tried several times to change the curve's parametrization, no changes

Hi,

I've never used it, but can you use a curve on suface for the original curve? If so, it might pull the curve normal from the suface normal which will always face out. So try taking your curve, extrude it a bit, and then grab an isoparm, or intersect a plane to make a cos and see if the script takes that.

This works well for a spline ik curve so the joints don't flip around.
