Bend

Bend makes a part curl instead of swinging like a plank. Press 🌿 Set bend area, then make two taps on the part: first where the bend begins (below that point it stays stiff), then the tip. Leaf-green dots mark the span. On the Animate card the action is called Bend area:

Now the Bend stepper in the pose controls curls the part between those two points: barely at the root, fully at the tip, in 15° notches up to a full curl either way. Tails, stems, antennae.

Bend is a pose control like any other: save a straight pose and a curled pose, press ▶ Play, and the part waves.

Tap the 🌿 Bend area ✓ · clear button to remove the area and make the part rigid again. Pressing Bend with no area set just reminds you to set one first.
