Accepted Answer

How much influence each bone has over individual vertices

Answer

The color of the character's skin texture

Answer

The specularity of the skin shader

Answer

Polygon smoothing groups

Question 4

What is a 'joint hierarchy' in a character rig?

Accepted Answer

A parent-child chain of joints that transmit movement from root to tips

Answer

The order of texture maps applied to the character

Answer

A sorting system for polygon groups

Answer

Question 5

What is the purpose of a 'bind pose' when rigging a character?

Accepted Answer

The neutral T-pose or A-pose from which skinning is calculated

Answer

A predefined animation cycle

Answer

The final rendered frame

Answer

A collision mesh pose

Question 6

What problem does 'volume preservation' solve in character skinning?

Accepted Answer
