It's hard to explain but some of these are alphas of other textures which affect each other. All the files that start with wing is the ones to create the DRS icon, those start with kers is KERS and those that start with revs is the speedometer HUD. Just export these textures and experiment with them. The reason why I could do this HUD without much problem because I used to mod GTA San Andreas. XDI'm sorry but I would like to modify my osd, but not which ones should I change ...
