Yeah I can imagine it being useful some things. It'd be easier to see how stable the ends are if it had images. There seems to be some scaling going on.
One of the challenges was to create a rigid chain that is pinned at both ends and droops in the middle. Chain links are rigid, so shouldn't stretch. In Arman's chain video he uses a path and and IK, but the movement is somewhat limited to keep the path length from fluctuating.
It's a really short chain

ur tests are very inspiring! thanks for sharing with us mate!
Jellyfish exercise. Learning so much already from Cydoni academy.
We did a cool jellyfish during the 4.2 beta, but sadly the project can't be opened anymore. We turned strength waaay down, so the long tendrils stay behind but react to the movement.
Nate Was there a video of it?
@Nate Yes, turning down the strength on the tentacles helps with the delayed reaction but also remain responsive. I was in hurry of finishing tentacle rigging and recording before work.
I think there were GIFs, but they got posted to a chat that doesn't keep the attachments. I've asked Soeren, maybe he still has them. It was a cool example of physics being a main component of the skeleton's motion.
Used rig from CydonimRoll course; artwork probably from Canva. Key-framing only a single bone on a path constraint. The fox has 2.5d face rig where the back bone moves oppositely from the front. CydonimRoll called it demonic.
looks good movement
