Hey guys, I've used Spriter before but primarily for straightforward stuff bone arrangements. I have an asset now which i want to use an octagonal 'foot' so to speak (picture here). If any of you remember the AT-HH hermit crab walker things from The Last Jedi it's the same concept. I want the topmost segment to be stationary and the rest of the octagon connected to eachother so that when i move the bottom of the 'foot' the rest of the joints will dynamically reorient themselves.Is there a way to create a closed loop of bones or am i going about this in the wrong way? Thanks a bunch regardless guys :).
