3D Texturing Quality Control & Assurance 2

Question 1

When reviewing a texture map for tiling artifacts, which method best reveals seam misalignment?

Accepted Answer

Apply the texture to a sphere and rotate it under neutral lighting

Answer

Applying the texture to a sphere and rotating it under neutral lighting exposes seam misalignment and tiling discontinuities that flat inspection misses.

Question 2

A metallic roughness texture appears too shiny in the final render but looks correct in the texture editor. What is the most likely cause?

Accepted Answer

The roughness channel is inverted in the engine

Answer

Engines can interpret roughness vs. smoothness channels differently, and an inverted roughness map makes surfaces appear shinier than intended.

Question 3

Which resolution is the minimum recommended for a hero prop texture set that will be viewed at close range in a AAA game?

Accepted Answer

2048x2048

Answer

2048x2048 is the standard minimum for close-range hero props in AAA games, balancing detail and memory budget.

Question 4

During QA, a texture artist notices color bleeding between UV islands on the baked ambient occlusion map. What should they adjust?

Accepted Answer

Increase UV island spacing/padding in the UV layout

Answer

Increasing UV island padding prevents color from one island bleeding into adjacent islands during baking and mip generation.

Question 5

What does a texel density audit ensure in a 3D production pipeline?

Accepted Answer

All assets have consistent pixel-per-unit ratios relative to their in-scene importance

Answer

A texel density audit ensures that assets maintain consistent pixels-per-unit across the scene so nothing appears blurrier or sharper than intended.
