well.. that's where it becomes complicated.. I've made quite some skins for planes, and I can't really offer them to anybody because I can't make a map
As maybe you might have heard before, the BMP files for the skins, are treated as a part of the terrain texture files.. thus, in order to use the customized skins, you have to build your own terrain.
I've learned to work on the skins, but I really don't know how to make a map.. I did make a small test map with only one field.. which, thankfully works without any errors, and it is on this map I try out my skins.. I've never used them in H2H tho..
So.. what you want to do is basically, grab all the skins you want, and request to someone who knows how to make maps to make you a very simple H2H map with the textures u have. That's the easiest way I can think of, m8..
