Textures of the aircraft in an aircraft container are specified by the files included in the Texture folder. The Texture folder contains .r8 files, which are 256x256 byte, 64K texture maps. Each byte in an .r8 file references a color in the range 0–255 in the Flight Simulator color palette.
Note: The texture (.r8) file names must correspond to the texture files that are referenced in the visual model (.mdl) file. If the file names don't correspond, the textures won't be visible.
