| Map Type | Function | |----------|----------| | | Defines the material's base color without light or shadow information | | Normal Map (GL) | Adds surface details (bumps, dents) without changing geometry. SketchUp requires GL-space normal maps — DX maps are incompatible | | Displacement Map | Actually modifies geometry for extreme surface detail (cracks, rough stone) | | Roughness Map | Controls how smooth or rough a surface appears — affects reflection sharpness | | Metalness Map | Determines whether a surface behaves like a metal (colored reflections) or a non-metal |
