Production texture guides

Practical guides for decisions 3D artists make before exporting procedural PBR maps.

PBR texture basics

Understand base color, normal, roughness, height, and AO as one material contract.

Use normal maps as lighting direction detail generated from height, not as painted color.

Check edge continuity, repeat scale, and visible motifs before using tiled materials on large surfaces.

Turn rules, seeds, and parameters into repeatable material variants that can be exported as map sets.

Pack occlusion, roughness, and metalness deliberately when an Unreal project expects ORM masks.

Convert roughness correctly when a Unity shader expects smoothness.

Know when to flip the green channel for Blender, Unreal, Unity, or custom shaders.

Choose texture resolution from camera distance, asset size, and memory budget instead of exporting 4K by default.

Set tile size and UV repeat so procedural materials read at believable physical scale.
