Well, I have seen people do these blue & white normal maps all over the place. But they do it incredibly quickly. I have to use alpha layers and do it completely by hand.

I use Sauerbraten a lot, the bump-mapped textures are incredible. Mine look like soggy reflection bags, and the normal maps are completely off.

Is it possible to do a bump-map in Blender, or even Gimp, without using smudge until I die from it?

I found a neat little GIMP plugin to generate normal maps off of a diffuse map. If you need it to generate a map different from what the diffuse map shows, then just make an altered version of the diffuse map

Here is the link to the tutorial which includes the plugin

While re-searching the plugin for you I've stumbled upon a plugin to support DDS in GIMP

And the linky to the DDS tutorial with the plugin on it

I should search around that site more

Dang, that little normal map plug-in is awesome! I tried it on sauerbraten, and it looked great. Thanks you very much the link!

You can generate a normal map for a low poly model with a highpoly version of that model. And there is the link for the software that will do for it for you - for free! Although creating a high poly version might sound like a pain, if you model the low poly version with edgeflow, a subvision or two will give you the highpoly version almost instantly! Your welcome.

Blender can do that too, but I don't know how to use the multires as a normal or specular mapping.

Speaking of specular mapping, does there happen to be a way to use this plugin for a specular map (Heightmappings for textures, rare in most games, common in games like Oblivion and Sauerbraten.)?

I find that a good solution to that is simply desaturating the diffuse map and fussing with the brightness/contrast a bit.

That might work, I'll give it a try.
