A spline based rig. An alternative approach to using PathDeform with more control over twist and scale.
1. Create a straight Spline – every vertex on that spline will be a helper to control the position
2. Run Script
3. Pick Spline
4. Adjust X Y Z to align the orientation of the box to your spline
5. Adjust width and length
6. Set twist helpers – this controls the amount of helpers to control twist and scale
7. Subdivisions – this controls the final resolution of your mesh
8. Press Go
You can use it it any way, even commercial. If you create something interesting I would love to see it – please drop me a mail
