Answer

A highly emissive surface

Question 3

What is a 'texture atlas' in game development?

Accepted Answer

A single texture image that contains multiple individual textures packed together

Answer

A document listing all texture file names in a project

Answer

A 3D reference sphere used to check material quality

Answer

Question 4

What information does the 'metallic map' store in a PBR workflow?

Accepted Answer

Whether a surface area is metallic (white) or non-metallic (black)

Answer

Specular highlight color

Answer

The roughness of metal surfaces only

Answer

Normal direction for metallic geometry

Question 5

What is UV unwrapping in game art?

Accepted Answer

Flattening a 3D mesh's surface into a 2D layout so textures can be applied correctly

Answer

Removing vertex normals from a mesh

Answer

Baking ambient occlusion onto a model

Answer

Applying a tiling material to a surface in the engine

Question 6

What is a 'texel density' and why does it matter in game texturing?

Accepted Answer

The number of texture pixels per unit of world space, used to ensure visual consistency across assets

Answer

The resolution of the normal map relative to the albedo map

Answer

The color depth of a texture file

Answer

The number of UV islands on a texture sheet
