SURF – Surface

SURF { name[S0], source[S0], attributes[SUB-CHUNK] * }

The name identifies the surface and matches a string in TAGS. When source is not empty, this surface is built on the named surface: it can override its settings and add texture layers to it. The sub-chunks are of two kinds: the basic parameters below, and surface blocks for texture layers and shaders. The basic parameters are the surface’s starting values before texturing, and are used for previews even when textures cover them. Most end in an envelope[VX], the index of an envelope that animates the value.

Basic parameters

Glossiness 0.2 gives an exponent of 16, the old “low” setting; 0.4 gives 64, “medium”; 0.6 gives 256, “high”; and 0.8 gives 1024, “maximum”. The description gives no defaults for the parameters left blank above.
