How to add normal mapping and glossiness to an .md3 model?

[Chip]

I've searched the internet with little success. I need to add some details to an .md3 weapon.

I'm using Darkplaces.

The weapon is located in models/weapons2/shotgun/.
The texture is located in the same folder, as per the .md3 path.

No problem so far, the diffuse texture appears correctly.

I want to add specular highlights (_gloss) and some depth (_norm).

Where (and how) should I put the textures?

I tried to put shotgun_gloss.tga in /textures/, in /progs/, in the same folder as the .md3 model... no success.

Also, what's the deal with .skin files? Could I add the _norm and _gloss textures there?

Help!

The gloss and norm would go in the same folder as the diffuse texture.
(diffuse-name)_norm/gloss. So if it was in ..../textures/shotgun/ the _norm/gloss go in there.

Have you tried changing some of the settings in Darkplaces? As both gloss and normal mapping can be disabled, or are they enabled but just not working on your model?

As for .skin files:
Those are used to make multiple skins for a single model. Like how Quake 3 has many skins for each player model. This just tells them what "group" on the model which texture to use.
