A three-joint IK/FK arm with premium ribbon twist on the upper arm and forearm, plus a full hand. The paid Advanced Ribbon arm.
WHAT IT DOES
The upgrade arm
Ribbon Arm is the upgrade arm. It does everything the free IK Arm does, then adds smooth ribbon twist running down the upper arm and the forearm, so the skin flows instead of pinching when the shoulder rolls or the hand pronates.
You get:
FK controls, an IK hand control, an IK/FK switch with match, and an auto-following pole vector
Smooth twist spread down the upper arm and the forearm, with floating tweak controls along each bone
Volume that holds the arm's shape as it twists and stretches
The same full hand as the free arm: a control per finger and a one-slider fist curl
- 1
Drop Ribbon Arm on a three-joint shoulder to wrist chain and build the rig.
- 2
Animate the arm exactly like the free arm (IK, FK, switch, pole vector, fingers, fist) - the twist works underneath on its own.
- 3
If you want, shape the twist with the floating ribbon controls along each bone.
- 4
Reach for Ribbon Arm when you want AAA-grade twist deformation. If you only need the basics, the free IK Arm covers them.
Filtered shoulder, carried wrist
The shoulder twist is filtered on purpose, so a plain shoulder bend does not candy-wrap the upper arm. The wrist twist carries through, so pronation reads in both IK and FK.
Set-and-rebuild options
Mid-control count and ribbon width are set-and-rebuild options - change them in Edit Mode and rebuild for them to take effect.
Tweaks follow the side color
The ribbon tweak controls follow the arm's side color by default. Recolor them only if you want them to read as a separate layer.
