AI Texture Generation for 3D Models Quiz

Answers and explanations appear as you take the quiz.

1. In a PBR material, what does the albedo or base color map represent?
   • The reflection blurriness
   • Surface color without lighting
   • The height of each bump
   • The object's transparency only
2. What does a normal map encode?
   • The overall shape of the mesh
   • How metallic the surface is
   • Color variation
   • Small surface bumps as per-pixel directions
3. What does the roughness map control?
   • How blurry reflections are
   • The texture resolution
   • The UV layout
   • The mesh's polygon count
4. Which technique helps a generated texture tile seamlessly?
   • Adding more lighting
   • Increasing roughness
   • Circular, wrap-around padding inside the network
   • Using a higher polygon mesh
5. How do methods like TEXTure and Text2Tex texture a mesh?
   • They scan the physical object
   • They render views, paint each with depth-conditioned diffusion, and project back into UV space
   • They copy textures from a stock library
   • They only generate a single flat color
6. Why is raw image generator output usually not a true albedo?
   • It contains baked shadows and highlights
   • It is always grayscale
   • It lacks any color
   • It is stored in the wrong file format
7. Normal maps look inverted in your engine. What convention difference is a likely cause?
   • Roughness stored in sRGB
   • Too many UV islands
   • A missing metallic map
   • OpenGL and DirectX normal maps differ by a flipped green channel
8. Which is an example of a physically inconsistent generated map set?
   • Low roughness on polished marble
   • Albedo without baked shadows
   • Metallic values on painted wood
   • A normal map stored in linear space
