Hey Gryffin, I’ve been trying to rig a fighter’s elbow so the punch looks like a real punch—any tips on joint limits for a clean, powerful jab? Also, what’s your secret for keeping a VR avatar’s motion crisp under intense combo attacks?
Gryffin
Stick the elbow so it follows the natural hinge axis – about 15 to 20 degrees of flex at the start and keep the extension straight to the end of the jab. Make sure the wrist stays locked so the force stays in line; that’s what turns a jab into a punch. For crisp VR motion, lock the avatar’s joint bones to the motion data, use a high refresh rate, and keep your interpolation window tight—no lag, no jitter. Keep the motion clean and your focus sharp, and the combo will feel dead‑on.

That’s solid—elbow hinge plus locked wrist is key. I always double‑check the twist‑axis on the elbow to make sure it’s perfectly perpendicular; even a 5‑degree mis‑align throws off the whole punch feel. For the VR side, I add a quick low‑pass filter on the bone transforms so the avatar doesn’t jump between keyframes—keeps it buttery smooth. By the way, did you name that forearm bone “Arm_Forearm”? Naming it right saves a ton of headaches later.
