The native SketchUp Materials only support a texture and a transparency value. Certain keywords in the SketchUp Material tell Enscape how to display it more realistically.
|Water, Ocean, River||Draws the material as a water surface.|
|Vegetation, Foliage, Leaf||Draws thin leafs with subsurface scattering like real vegetation.|
|Emissive||Emissive material based on the material color.|
|Grass||Realistic grass material based on the underlying surface color.|
Those keywords change the material parameters without changing their color. The color is still defined by the SketchUp texture. The SketchUp default roughness is 1.0.
|Steel, Copper, Metal, Aluminium||0,3||Metal|
|Carpaint, Polished, Acryl||0,02||–|
