This is a modified shader for Doom 3 and RoE that gives high quality dynamic highlights and enhances the 3D look of the surfaces. Any hardware capable of the ARB 2.0 path can run this mod. Regarding performance, it favours math power over memory bandwidth as this is the current trend.-------------Features:-------------:: Dynamic highlights ::Using the original specular mapping from the game, my shader adjusts the highlight falloff separately per pixel. :: Highlight masking ::Like in the built-in shader, the specular map is also used to mask the highlights from less shiny surfaces.A Quake 4 version of this mod is available at Quake 4 Files.
