I've also tried to promote the feature, so other mods use it...
So far it's mostly standard FS2 and SoL.
It's far easir for me to create normal maps for stuff I've the source files for...
Heh, tell me about it. That said, my normal maps thus far have all been too strong and visually rather crappy because I had no idea what I was doing. Thus far only the loki has decent normal maps, but they're still too strong. I'll get it right eventually.

How do you do yours btw, since yours are looking much nicer? Also, I'm not up to speed with what's happening with Blackhole's parallax mapping. It uses a heightmap, but is that heightmap supposed to be included in the DXT5_NM texture, or is it still a separate file?
