A Point Constraint makes the constrained object's translation match the position of one or more target objects.

Question 3

What is the purpose of a 'Pole Vector Constraint' in Maya IK rigs?

Accepted Answer

Controls the direction the middle joint (knee/elbow) bends toward

Answer

The Pole Vector Constraint aims the middle joint of an IK chain (like the knee or elbow) toward a control object, preventing unpredictable flipping.

Question 4

What are 'blend shapes' used for in Maya character rigging?

Blend shapes (morph targets) interpolate between a base mesh and target meshes, commonly used for facial expressions and corrective shapes.

Question 5
