I asked the same question on Simhq but didn't got an answer so I try it again here. I have followed your tutorial and the weapon shows up in the loadoutscreen and I can load it on the plane but when I start playing they aren't visible on the plane (Fueltanks with another texture than in the weaponspack on the F-14). It just like the the pylon is empty, I don't know if it is the lodfile or the bmp that doesn't work I renamed both the lod and the bmp because I don't want do save over the one in the weapons pack.
