I've been trying to make this fidget toy and am having difficulty rigging. Would anybody know a way to rig this. Its a closed loop like a chain. and the pieces connect with a little peg so these can only rotate on a 360 swivel. Ideally id like to be able to pose the toy with freedom like using it if possible. cant get my head around how to go about this. I had been adding two bones per segment at a right angle to one another. Or would i be better doing this using physics simulations?
Here is a simple setup, what I have made using IK:
Every bone is corresponding to one segment and one rotation:
Last bone is IK target
Last important thing is blocking all axis except Y in IK settings for every bone in chain:
Note, Rotation in IK constraint useful to detect last segment
