When your Biped decides to be a statue instead of animating πŸ—ΏπŸ’ƒ

The Biped system in 3ds Max can be your best ally... or turn into that nightmare where the arms don't move and the footsteps magically disappear. But don't throw your keyboard yet, we have the solution to bring your character back to life.

"A poorly configured Biped is like a broken ventriloquist dummy: it neither speaks nor moves, but embarrasses you just the same" β€” Frustrated animator.

Diagnosis and step-by-step solution

  1. The magic switch: Figure Mode vs Motion Mode
    • Figure Mode ONLY for adjusting proportions
    • Motion Mode FOR ANIMATING (always disable Figure Mode)
    • "Figurine" icon off = animation mode active
  2. Problems with static arms
    • Open Track View > Curve Editor
    • Check that rotation controllers are not locked
    • Switch to Euler XYZ if they are in quaternions
    • Check hidden constraints in the stack
