Game Art 3D Modeling for Games 2

Question 1

What is the purpose of a 'cage mesh' during normal map baking?

Accepted Answer

To control ray projection direction and distance during baking

Answer

To define UV islands

Answer

To set the polygon budget for LODs

Answer

To store vertex color data

Question 2

What does the term 'silhouette read' mean in game character modeling?

Accepted Answer

How recognizable a character's shape is from its outline alone

Answer

The color contrast of a character against a background

Answer

The number of polygons visible on screen

Answer

The ambient occlusion pattern on the character

Question 3

In game modeling, what is a 'modular kit'?

Accepted Answer

A set of pre-built reusable mesh pieces designed to snap together

Answer

A collection of character animations

Answer

A library of pre-made shaders

Answer

A UV layout template

Question 4

What is 'retopology' in a 3D game art workflow?

Accepted Answer

Rebuilding a cleaner, game-ready mesh over a high-poly sculpt

Answer

Applying a new UV map to an existing mesh

Answer

Baking ambient occlusion from a scene

Answer

Merging multiple meshes into one object

Question 5

Why are triangles (tris) often used as the final export format for real-time game engines?

Accepted Answer

GPUs process triangles natively and quads are split at runtime anyway

Answer

They render faster in post-processing

Answer

They use less texture memory

Answer

Animation rigs only work with triangle meshes

Question 6

What is the function of vertex normals in a low-poly game mesh?

Accepted Answer

They control how light interacts with the surface to simulate smoothness

Answer

They define the mesh's bounding box

Answer

They store UV coordinate data

Answer

They determine the mesh's LOD switching distance
