Inverse Kinematics

Check also my thread and PG, I decided to write from scratch my IK algorithm because I don’t understand how bones work in babylon…

Weird behaviour while rotating intersection (manually calculating Inverse Kinematics)

This is my playground: https://playground.babylonjs.com/#D25VJD#14 When I rotate the vertical wall around its vertical axis, intersection does not rotate: [image] When I rotate around Z, thins get even weirder… [image] What’s going on here?!?
