3D Texturing Professional Standards & Competencies 3

Question 1

In a professional VFX studio, what is the correct colorspace to use when painting albedo/diffuse textures in Substance Painter?

Accepted Answer

sRGB

Answer

Albedo/diffuse textures should be painted in sRGB colorspace because they represent color as perceived by the human eye, and the renderer will apply linearization at render time.

Question 2

What does a professional texture artist typically include in a texture LOD (Level of Detail) strategy for a AAA game?

Accepted Answer

Texture sets at 4K, 2K, 1K, and 512px for different viewing distances

Answer

A proper LOD texture strategy provides multiple resolution variants (4K down to 512px) so engines can stream appropriate resolutions based on the asset's screen-space size.

Question 3

When freelancing for a client in the film industry, which professional practice protects both parties regarding texture asset ownership?

Accepted Answer

Including IP assignment and usage rights clauses in a written contract

Answer

A written contract with explicit IP assignment clauses is the professional and legally binding way to define who owns deliverables and how they may be used.

Question 4

A senior texture artist reviews your work and says your normals are 'baked in the wrong tangent space.' What does this mean?

Accepted Answer

The normal map was created for a different rendering engine or tool than where it's being used

Answer

Tangent space normal maps are calculated relative to a specific coordinate system; baking in Mikk TSpace for one engine and using it in another with a different tangent basis causes lighting artifacts.

Question 5

What is the professional standard minimum padding (gutter) width between UV islands on a 2K texture to prevent mip-map bleed?

Accepted Answer

4 pixels

Answer

A minimum of 4 pixels of padding (gutter) between UV islands on a 2K texture prevents color bleeding between islands when lower mipmap levels are sampled by the GPU.
