Blender Blender Rigging & Armatures 3

Question 1

What does the 'IK Solver' constraint in Blender do?

Accepted Answer

Calculates inverse kinematics so a chain of bones bends toward a target object

Answer

Solves physics simulations for bones

Answer

Renders bones as solid objects

Answer

Inverts bone rotation directions

Question 2

In Blender rigging, what is the 'Pole Target' in an IK setup used for?

Accepted Answer

A secondary target that controls which direction the middle joint of an IK chain bends toward

Answer

The final IK target position

Answer

A target for root motion control

Answer

A pole used for camera tracking

Question 3

What is 'Bendy Bones' (B-Bones) in Blender?

Accepted Answer

Bones that can display as segments with curve handles for smooth arc deformations

Answer

Bones with soft body physics

Answer

Bones that bend automatically with gravity

Answer

Circular bones for limb rolling

Question 4

What is the purpose of the 'Bone Groups' feature in Blender?

Accepted Answer

Assigning bones into color-coded groups for visual organization in Pose Mode

Answer

Organizing bones into physics groups

Answer

Grouping bones into separate armature objects

Answer

Defining bone collision groups

Question 5

What does 'Inherit Rotation' toggled off on a bone in Blender mean?

Accepted Answer

The bone does not inherit rotation from its parent bone, keeping a fixed orientation in world space

Answer

The bone ignores all constraints

Answer

The bone cannot be keyframed

Answer

The bone inherits only scale, not rotation

Question 6

In Blender, what is the 'Stretch To' bone constraint used for?

Accepted Answer

Making a bone automatically scale to always point and reach toward a target object

Answer

Stretching the mesh along the bone's length

Answer

Animating squash and stretch on a mesh

Answer

Setting rest pose stretch length
