I'm trying to make a mod for the Miramar that adds halo HID headlights (and later LED taillights) but they dont show up in game, i had the thought that you cannot add custom light textures because everything else looks fine, but that doesn't explain why they aren't even listed in the headlights option thingy. I initially just replaced them just for my game but they looked so good i wanted to make them into a mod but i guess i messed something up or something.
the materials will not work as it collide with the one from the game. put it inside a folder (eg: MiramarHaloHeadlights.zip\vehicles\miramar\halo_headlight\materials.cs) Also it overwrite the default materials. you should provide a custom mesh with different material name else it will clash with vanilla materials. Once you changed the names of the materials you will need a new glowmap section
