Controls: click on either the upper or lower arm, and rotate them with the joystick on the bottom right TRUST THE PROCESS this is a part of my revamp of my old rig, which was AWFULLY unoptimized, so this is my first step to optimizing it. How it works (Currently): The child limb (lower arm) turns into a circle, using the parent (upper arm) to calculate its edge, in this project- a joint, the circle then changes back into the lower arm, so even if the position of the upper remains the same but its direction changes, the lower arm can still follow up. And since the lower arm's calculation process is ran without screen refresh, it doesn't affect costume changing mid-movement, try it!
