Others also do it on given texture files. My problem is probably more to do with my Gimp skills in that I am not following post $4's steps correctly somehow.
He is doing the same thing almost, but instead of using a black and white height map, it looks like he is using a normal map. It appears to work in this case as a height map.
Gimp's bump map plugin only reads the luminosity values, so it reads the normal map as if it is a black and white height map.
Here it is scaled down and grayscale:
But it is not height map, if you notice the shading
I see; so as the texture in any case is applied over a 3D aircraft, the parts which seemed to be raised are probably already raised on the aircraft. Really what I need are the rivets (up) and panel joins (down), so I am busy now erasing all but these!
