Game Art Game Art MCQ 3 — Questions and Answers
Question 1: What is a trim sheet in game art production?
- A grid used to align HUD elements
- A single tiling texture atlas containing repeating architectural detail strips (Correct answer)
- A script that trims unused vertices from a mesh
- A LOD bias setting in the engine
Correct answer: A single tiling texture atlas containing repeating architectural detail strips
A trim sheet is a modular texture containing rows of tileable detail (edges, panels, vents) that artists reuse across many meshes to share one texture atlas.
Question 2: Which rendering technique pre-computes lighting and stores it in a texture to save runtime cost?
- Ray tracing
- Lightmapping (Correct answer)
- Deferred rendering
- Screen-space ambient occlusion
Correct answer: Lightmapping
Lightmapping bakes static light and shadow data into UV-unwrapped textures, so runtime lighting for static geometry is nearly free.
Question 3: What is the purpose of a roughness map in PBR shading?
- It stores the height of surface bumps
- It controls how blurry or sharp specular reflections appear (Correct answer)
- It masks transparent areas of a surface
- It defines the base color of a material
Correct answer: It controls how blurry or sharp specular reflections appear
The roughness map drives microsurface scattering: low values produce sharp mirror-like reflections, high values produce broad diffuse highlights.
Question 4: Which file format is commonly used for game-ready 3D asset exchange that supports meshes, rigs, and animations?
- .OBJ
- .FBX (Correct answer)
- .PSD
- .SVG
Correct answer: .FBX
FBX (Filmbox) is the industry-standard interchange format that carries geometry, skeleton, skin weights, and animation clips into game engines.
Question 5: What is the primary purpose of ambient occlusion (AO) in game art?
- To define specular intensity
- To darken crevices and contact areas where indirect light is occluded (Correct answer)
- To simulate real-time global illumination
- To add subsurface scattering to skin
Correct answer: To darken crevices and contact areas where indirect light is occluded
AO approximates how much ambient light reaches a surface point, darkening corners and cavities to add perceived depth and grounding.
Question 6: In sprite-based 2D game art, what does the term 'pivot point' refer to?
- The center of the game world
- The anchor point around which a sprite rotates and scales (Correct answer)
- The frame where an animation loops
- The pixel coordinates of a sprite's top-left corner
Correct answer: The anchor point around which a sprite rotates and scales
The pivot point is the local origin of a sprite; rotations, scaling, and position offsets are all calculated relative to it.
Question 7: What does 'tiling' refer to when applied to a texture in a game engine?
- Dividing an image into mipmap levels
- Repeating a texture across a surface by wrapping UV coordinates (Correct answer)
- Rendering a texture at half resolution
- Merging two textures using blend modes
Correct answer: Repeating a texture across a surface by wrapping UV coordinates
Tiling (or UV wrapping) repeats a small texture seamlessly across a large surface by letting UV coordinates exceed the 0–1 range.
