Game Art Game Art MCQ 2 — Questions and Answers
Question 1: What is the purpose of a normal map in 3D game art?
- To define the color of a surface
- To simulate fine surface detail without adding geometry (Correct answer)
- To control the transparency of a mesh
- To store ambient occlusion data
Correct answer: To simulate fine surface detail without adding geometry
Normal maps encode surface direction data in RGB channels to fake high-frequency detail on low-poly meshes.
Question 2: Which color space should diffuse/albedo textures typically be stored in for physically based rendering?
- Linear
- sRGB (Correct answer)
- HDR
- CMYK
Correct answer: sRGB
Albedo textures are authored in sRGB because that matches how monitors display color and how artists perceive them.
Question 3: In a PBR metalness workflow, what value should a pure metal surface have in the metalness map?
- 0
- 0.5
- 1 (Correct answer)
- 128
Correct answer: 1
A value of 1 (white) in the metalness map marks a surface as fully metallic, affecting how reflections and albedo are interpreted.
Question 4: What does LOD stand for in the context of game asset optimization?
- Level of Detail (Correct answer)
- Line of Definition
- Layer of Depth
- Lighting on Demand
Correct answer: Level of Detail
Level of Detail (LOD) systems swap high-poly models for lower-poly versions as objects move farther from the camera.
Question 5: Which UV mapping technique is best suited for seamless tiling on large terrain surfaces?
- Planar projection
- Triplanar mapping (Correct answer)
- Cylindrical projection
- Spherical projection
Correct answer: Triplanar mapping
Triplanar mapping blends three orthogonal projections to eliminate visible seams on complex terrain without explicit UV coordinates.
Question 6: What is texture atlasing in game development?
- Applying a texture to a sphere
- Combining multiple textures into a single image to reduce draw calls (Correct answer)
- Scaling textures based on screen resolution
- Baking global illumination into a texture
Correct answer: Combining multiple textures into a single image to reduce draw calls
A texture atlas packs many smaller textures into one sheet so the GPU can render multiple objects in a single draw call.
Question 7: In character rigging, what is the role of an IK (Inverse Kinematics) chain?
- It bakes lighting onto character skin
- It automatically calculates joint rotations from a target end-effector position (Correct answer)
- It generates normal maps from a high-res model
- It compresses animation data for export
Correct answer: It automatically calculates joint rotations from a target end-effector position
IK solves the required joint angles so that the end of a limb (like a hand or foot) reaches a specified target point.
