Question 1

What is texture baking in 3D production?

Accepted Answer

Rendering lighting and surface details from a high-poly mesh onto a low-poly mesh's UV map

Answer

Texture baking transfers detail (normals, AO, color) from a high-resolution model onto a texture map for use on a low-poly version.

Question 2

What is a Displacement map used for in 3D rendering?

Accepted Answer

Physically push geometry based on grayscale texture values at render time

Answer

A Displacement map actually moves surface geometry at render time based on pixel values, unlike Normal maps which only fake it.

Question 3

In texturing, what does 'tiling' refer to?

Accepted Answer

Repeating a texture pattern across a surface multiple times

Answer

Tiling repeats a texture seamlessly across a surface, allowing small textures to cover large surfaces without stretching.

Question 4

What is a Subsurface Scattering (SSS) shader used to simulate?

Accepted Answer

Light penetrating and scattering inside translucent materials like skin or wax

Answer

SSS simulates light entering a surface, scattering beneath it, and exiting at a different point, crucial for realistic skin rendering.

Question 5

What resolution is commonly used for game-ready textures to balance quality and performance?

Accepted Answer

2048x2048 (2K)

Answer

2K (2048x2048) textures are the standard balance between visual quality and GPU memory usage in modern game production.
