Let me be more specific with my question.
I downloaded a whole bunch of airports by John Loney. In his sceneries, the ones that have textures, they usually have a texture folder to go along with the scenery folder and they both go in the main scenery folder that goes in addon scenery.
However, in a few of his sceneries, he specifies some texture files (mainly for signs and stuff like that) go in the main texture (the one in the root directory) folder. Other scenery designers do the same thing. Why?
My understanding is the scenery will find and read the texture file regardless of whether it's in the texture folder within the scenery folder or the main texture folder. Right?
Why not just put ALL the texture files for a scenery in the texture folder that goes with the scenery? Why make it more complicated?
And what would happen if I put those 'main texture' bmp files in the texture folder with the scenery?
