Brilliant highlights NG
Ver 1.3


What is it?

A modified shader for Doom 3 (and RoE) that gives high quality dynamic highlights and enhaces the 3D look of the surfaces.

- 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.

- Removed plastic look & added Metallic look !!! (by DFM).

- Compatibility. Any hardware capable of the ARB 2.0 path can run this mod.

- Performance. BH mod favours math power over memory bandwidth as this is the current trend.

Note...: Not to be confused with latest superior version by Maha-X, this is the NG version of the old v0.6b, mh, anyway, soon will be the
NG of the latest, admired Maha-X permision of course. :D


This mod uses amazing TheRealSceneGraphManager's NEW Chromatic Dispersion Special FX !
Thanks to Maha-X, of course.

So how do I install?

Extract the folder named glprogs to your base and d3xp folders and "Dynamic highlights NG" will be used for all the Doom 3's mods that do not use any other glprogs folder. The mod will then be automatically (and allways) enabled.


Sometimes you might see yellow or green objects that are not supposed to look that way. Very rare tough. Just keep in mind, this is a beta release, it has been only tested in a number of levels.

You may use only the interaction.vfp, removing the other files that are inside glprogs folder, but the interaction.vfp file !

Remember that the glprogs folder is not a MOD folder, it's a folder to be added into base and d3xp folder or into any other folder mod, ok !!!

What else?

For the more tweaker in heart; you can adjust the minimum and maximum power and the minimum mask within the shader. The comments describe how.


Sure; mail me at


See Doom 3 eula. Also, if you want to use my mod, ask. Not that I wanted to say no, just that I know. And credit me where required.
