Yeah... I see you've fixed the timeline! That's fantastic. Great many thanks, man!
As for the joints, I like this approach. A couple of questions right off the bat:
1) how to control distance between joints?
2) Multiply controls under the child mesh seem useless (and they occasionally crash wz4). Is that the correct behavior?
3) I also wonder how you are planning to implement more complex hierarchies: chains, ropes etc. I mean... this will require more joint operators, right?
