Game Art Game Art MCQ 5

Question 1

What is 'skinning' in 3D character art?

Accepted Answer

Binding mesh vertices to skeleton bones with weighted influences

Answer

Skinning (vertex weighting) assigns each mesh vertex influence values to one or more bones so the mesh deforms smoothly as the skeleton moves.

Question 2

What distinguishes a roughness-metalness PBR workflow from a specular-glossiness workflow?

Accepted Answer

Roughness-metalness separates conductors via a binary metalness mask; specular-glossiness defines F0 directly in the specular map

Answer

The metalness workflow uses a grayscale mask to choose between dielectric and conductor BRDF behavior, while spec-gloss encodes the actual specular reflectance color.

Question 3

Why is it important to keep a game character's mesh symmetrical during the initial modeling phase?

Accepted Answer

It allows artists to work on one half and mirror it, saving time and ensuring consistent edge loops for rigging

Answer

Modeling one side and mirroring maintains perfectly matching topology, which is critical for clean deformation when the rig is applied.

Question 4

What is 'vertex color' used for in game art pipelines?

Accepted Answer

Storing per-vertex data such as blend masks, AO, or foliage stiffness directly in the mesh

Answer

Vertex colors bake per-vertex RGBA data into the mesh itself, used by shaders for blending terrain layers, tinting, or physics parameters like wind stiffness.

Question 5

What is the function of a 'morph target' (also called a blend shape) in character animation?

Accepted Answer

It stores an alternate vertex position state that can be blended to drive facial expressions or secondary deformations

Answer

Morph targets define a delta mesh where vertices are offset from rest pose; blending between them drives expressions, lip sync, or corrective shapes.
