ok... from what i remember (it´s been a while) in order for the alpha channel to work as reflections.... (i assume that´s what youre asking) your texture file MUST have a _t suffix to it (i.e. fuselage_T)

this tell FS that your texture has a reflection map (it also tells that there might be a nightlight texture, but that´s a whole different story)

the alpha channel is basically a grayscale image that is compiled with the original bitmap using DXTBMP or similar... as i remember, totally black is full reflection and white is no reflection (it might be the other way around, but that´s an easy fix)

the alpha channel image must be of the same dimensions as the texture bitmap... actually, an easy way to do it is to simply convert your texture to grayscale and go from there....

this way, you are really "painting" the reflections on your texture

about the night lighting question.... the night light textures are also grayscale images... only, this time they are a separate file, which has it´s own little quirks....

in the nitelite texture, the areas painted white(er) will light up the original texture "beneath" it when you turn on the landing lights... nitelite textures must have the same name as the base texture, but with the _L suffix applied (i.e. fuselage_L.bmp)

and about that mapping problem you´re having.... im not sure what might be causing it.... but i´d double check all filenames and also check if there isn´t an option in makemdl or something that might be not exporting the texture mappings

hope this helps
