Describes how to simulate various types of surface materials by using either an image file or a computer graphic procedure.
Surface textures are two-dimensional textures that simulate various types of surface materials by using either an image file (File and Stencil textures) or a computer graphic procedure (Bulge, Checker, Cloth, Curvature, Fractal, Grid, Highlight, Mountain, Noise, Ramp, and Water textures).
Environment textures map to directions. Surface textures and solid textures map to positions.
Do not map a surface texture to a shader’s Reflection parameter because it does not produce realistic-looking reflections.
