Game Art 3D Modeling for Games

Question 1

What does LOD stand for in 3D game modeling?

Accepted Answer

Level of Detail

Answer

LOD (Level of Detail) refers to using lower-polygon versions of a mesh as objects move farther from the camera.

Question 2

Which polygon count range is most common for a game-ready hero character in a modern AAA title?

Accepted Answer

20,000–80,000

Answer

Modern AAA hero characters typically use 20,000–80,000 polygons to balance visual fidelity and performance.

Question 3

What is 'edge flow' in 3D character modeling?

Accepted Answer

The arrangement of edge loops to support deformation

Answer

Edge flow describes the arrangement of edge loops so that a mesh deforms naturally during animation.

Question 4

Which topology technique involves connecting faces with exactly four sides throughout the mesh?

Accepted Answer

Quad topology

Answer

Quad topology uses four-sided polygons (quads) to keep meshes clean, predictable, and animation-ready.

Question 5

What is a 'high-poly bake' in game asset production?

Accepted Answer

Transferring surface detail from a dense mesh to a low-poly via normal map

Answer

A high-poly bake transfers fine surface detail from a high-resolution sculpt onto a low-poly mesh through normal or displacement maps.
