How to use normal maps?

[ChupaReaper]

how do I add normal maps, do I have to reference them in XML, save the normal map texture with the same name as a model texture but with _n or something or does it have to be set in blender before exporting the model?

Edit: Off topic, I can't find info on how to use the stealth/cloaking features on the wiki either, anywhere I can find out how all these new features are used and if there's any features I don't know about yet?

They need the same name as the diffuse texture, with _normal added to the end, before the extension, obviously

However, the normal mapping is defective on the version you have now built yourself... It has been fixed, but the fixes haven't been "pushed" onto the sourceforge repo yet because I got it mixed up with some other (incomplete) work on the renderer.

I was hoping to have that finished, merged & pushed next week some time... but I'll have a look and see if I can't extract it cleanly, or just disable the other stuff, so I can push it this weekend.

Cool thanks, I'll start gathering all my normal maps in a folder somewhere ready to move across in gae.
Also I found a Cloaking topic which explains how to use that so I'm going to give that a try.

Cool, I imagine for most of the models in your mod it wouldn't make much sense, but in case you have specular maps for any of them lying around, you may want to collect those too [for future use, might be a few weeks before we get around to adding the support for them].

Ahh, I have a lot of specular maps too, I'll get them sorted too, GAE is going to look very pretty!
Do bump maps work on map surfaces? And will spec maps be _specular?
