Ribbon/Spline Rigging

[bryan549QZ]

Hello, i have been struggling with this rig for days now to no end.

How would one rig and achieve an animation for a gym strap (see picture attached) to start from a flat strap and comes in to go through the hole and then wrap back around. 

2 methods i have tried and the same issues i have faced:

1. Ribbon Rigging method, gets a nice deformation but no rotation controls. ribbon rigging method stretches the mesh which would just destroy all my UVs.

2. Bone Rig/Spline IK method, has rotation but get weird deformations when it the joints get too close with each  other(it would almost be touching). also this methods dosent give me a smooth curve.

The main issue is keeping the shape of the logos and getting a nice, curved deformation.

If anyone has any ideas it would be gladly appreciated!

Hi!

If you don't mind me asking, why aren't you using FK to do this animation? This seems like something that could be pretty easily animated with just an FK chain.

You could also ensure that you don't stretch your ribbon too much by arranging your driver joints in an FK type setup and only using rotation to animate your setup.
