im uber confused

Well IIRC, the greyscale texture ( _n ) is what gives it it's bumpiness. So he must have compiled it with just the bumpmap which makes it look like a greyscale texture

[Muffie]

I use normal maps for mine? is that wrong?

[TwentySeven]

_n is supposed to be normals, not a greyscale bump.

Updated with some fixes to q3map2_radbump.

ok, i tried this out and tested it, with and without -radbump on the light stage. I get same results, cept everything is alot shinier/glossier then before.

For a lot of textures that are used they have the shadows baked into them already so you won't notice a great deal of difference with no specularity (black alpha).  What this does is use the normal map to add the shadows to the texture so gives the texture more depth and realistic shadows for the current lighting.  It doesn't actually modify the surface.  To see the best results use a flat/non shaded texture (evenly lit) and a normal map.

If you add the specular in (make alpha channel more white) it gives the appearance of more depth especially when moving around but does give it that wet look.

TwentySeven's test room with a single light in a corner shows off the process the best, you will notice that the bumps in the texture have shadows away from the light.

One error I did find using the -bounce 8 (turns on radiosity ? with 8 bounces) it duplicates the light source has some artifacts.  Here is an example: screenshot and screenshot of radiant

Yep yep, theres still some bugs in it.

It seems -super and -bounce arn't playing together nicely yet.
