Question by blitzen · Nov 09, 2016 at 03:22 AM · mesharmature

Curving the Axis of an Armature

I'm trying to make the axis of a gradually-widening rotating spiral also curve, as per a rope that you attached to the propeller of a boat that's turning in the water:

This bend of the axis will want to occur smoothly between right and left - perhaps in a blend tree - such that when you average them halfway in between, the result is twirling straight up and down:

alt text

I have in this attempt arranged in Blender a string of sixteen bones into the spiral shape as it will also undergo other dynamic motions. I've yet to see if that is plausibly speed-efficient when there are hundreds of such boats on screen, each dragging multiple twirling ropes.

Is there a way in the Unity side to warp a mesh's bones according to e.g. a Bezier curve, or another idea?
