Leaderhead textures: nrml?

[Longinus]

I was modding leaderhead textures and while I could pretty much figure out what the other texture files do, but I'm not sure about one called (leader)_nrml. What does it do? It might be somekind of a bump map, but unlike bump maps usually it has funky colours. If it is a bump map how it can be edited without messing it up and what the colours are for? If not what does it do then?

hmm... might be a tangent space normal map


characterized by being mostly pale blue with reds yellows and greens creating the 3dimensional details.

Yes that's exactly what it looks like! I just have no idea of how it works, so I have no idea how to mod it...

Create a high poly version of your leaderhead, then bake it onto a low poly version.

You bake it on with a program like MeLODy by NVidia.
