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 > Specular Material.

Data Layout

4b - FLOAT   - Specular Level
 ? - CHAR[?] - Specular Texture Name, see below
4b - DWORD   - unknown, always 0 (zero)

Annotations

Specular Level 

0.0 is no spec and 1.0 is full spec. Values can go past 1.0, but may produce unrealistic results.

Specular Texture Name 

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 aligned to 4 byte boundaries with extra zeros appended.

Notes

The Specular Material 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.
