|Does anyone know if it's possible for FG to work with a texture which consists of two images, and manipulate those images seperately? The application here is airframe dirt - I'm trying to find out if I can have one texture for the aircraft livery, and another for accumulated dirt, which would gradually become less transparent as the airframe hours increase. I am aware of the questionable advisability of using alpha channels excessively in FG, this is just an experiment at the moment. | |Does anyone know if it's possible for FG to work with a texture which consists of two images, and manipulate those images seperately?
