A Reflection Material is one of Rockstar's custom sections. In GTA San Andreas it is used to override vehicle reflection maps. The typical location in a SA vehicle dff section hierarchy is Clump > Geometry List > Geometry > Material List > Material > Extension > Reflection Material.

Data Layout

16b - FLOAT[4] - Environment texture transformation params
 4b - FLOAT    - Reflection Intensity
 4b - DWORD    - Environment texture ptr, always 0 (zero)

Struct unpacked

struct gtaReflectionMaterialPlg
{
    char       m_cTransformParam[4];
    char       m_cIntensity;
    short      m_sRenderFrame;
    RwTexture *m_pEnvMap;
};

Annotations

Reflection Intensity 
Defines how much of the image will be reflected back – 0.0 for none to 1.0 for full.

The Reflection Material is exclusive to San Andreas. The use is limited to vehicles; putting this Material extension on a building object will not yield the same results.
