Game Art Game Animation Principles

Question 1

What is a 'rig' in 3D game character animation?

Accepted Answer

A system of bones and controls layered over a 3D mesh that animators use to pose and animate the character

Answer

The collision mesh used for the character's physics

Answer

The LOD system managing character polygon counts at distance

Answer

The blend tree connecting a character's movement animations in engine

Question 2

What is 'squash and stretch' as applied to game animation?

Accepted Answer

An animation principle that exaggerates deformation to convey mass, weight, and impact during movement

Answer

A UV distortion technique for deforming cloth materials

Answer

A LOD blending technique between animation states

Answer

A compression format for storing keyframe data

Question 3

What is 'anticipation' in game character animation?

Accepted Answer

A preparatory motion before the main action that primes the player to perceive the incoming move

Answer

A predictive pathfinding algorithm used in AI movement

Answer

An audio cue that plays before a character speaks

Answer

A blend weight that increases before a transition between states

Question 4

What does 'follow-through' mean in game character animation?

Accepted Answer

The continuation of movement in secondary elements (hair, clothing) after the main body motion has stopped

Answer

Completing the full design pipeline before handing off to the engine team

Answer

Extending an animation's timeline to prevent early looping

Answer

Following a character path node to its end point in AI navigation

Question 5

What is 'secondary animation' in game character art?

Accepted Answer

Motion applied to non-primary elements like hair, cloth, and accessories that react physically to the character's main movement

Answer

Animations triggered only by scripted story events

Answer

The idle animation state in a character's blend tree

Answer

LOD2 animations with reduced bone counts for distant characters

Question 6

What is a 'root motion' animation in game development?

Accepted Answer

An animation where the character's actual world position is driven by the animation data itself rather than external engine movement code

Answer

An animation that plays when a character touches their root bone to the ground

Answer

The idle animation assigned to a character's root state in a blend tree

Answer

A motion capture session captured from the root joint only
