File Format

A Specular Material is one of Rockstar's custom sections. In GTA San Andreas it is used to store material information for specular lighting. The typical location in a SA dff section hierarchy is Clump > Geometry List > Geometry > Material List > Material > Extension > 0x0253F2F6.

The layout of a Specular Material Extension is as follows:

Spec

float - specular level.
string - Specular Texture.
dword - always 00.

Explanations

Specular Level - where 0 is no spec, and 1.0 is full spec. Values can go past 1.0, but may produce unrealistic results.
Specular texture - On the PC and Xbox versions of the game, this texture is not used. On the PS2 however, it is used as a second reflection map. The string is null terminated, and byte-aligned with extra 00's appended.

Notes

The Specular Section is exclusive to San Andreas, and Manhunt. In San Andreas, the use is further limited to vehicles; putting a Specular Material extension on a building object will not yield the same results. Its use in Manhunt is unknown.
