3D Texturing Case Studies & Practical Application 2

Question 1

A game artist notices that a brick wall texture looks blurry at close range but sharp from a distance. What is the most likely cause?

Accepted Answer

The texture resolution is too low for close-up viewing

Answer

Low texture resolution causes blurring at close range because there aren't enough texels per screen pixel.

Question 2

A film VFX artist is texturing a destroyed concrete pillar. Which workflow best captures realistic surface variation?

Accepted Answer

Combine photogrammetry-derived diffuse maps with hand-painted edge damage

Answer

Combining photogrammetry diffuse maps with hand-painted edge damage provides realistic base variation and believable wear patterns.

Question 3

During a product visualization project, a rendered leather handbag looks plastic despite having a roughness map. What should the artist investigate first?

Accepted Answer

Check whether the roughness map is connected to the correct channel in the PBR shader

Answer

If the roughness map is connected to the wrong channel, the renderer ignores it and falls back to a default smooth surface.

Question 4

A mobile game team needs to texture a 500-polygon character model while keeping draw calls low. What approach is most appropriate?

Accepted Answer

Pack all texture regions onto a single atlas texture

Answer

A single texture atlas allows all material zones to share one draw call, minimizing GPU overhead on mobile hardware.

Question 5

A studio is converting an existing PBR metallic-roughness model for use in an older engine that requires specular-gloss textures. Which channel mapping is correct?

Accepted Answer

Roughness → Glossiness (inverted), Metallic → Specular color

Answer

In specular-gloss workflow, glossiness is the inverse of roughness, and specular color is derived from the metallic mask applied to the albedo.
