Edit - This has since been fixed, with the help of @Firepower ! Hey there, So, on a WIP mod which I won't name (because it's being kept a secret until release,) I've been having real trouble with glowMaps - which just stay a solid white all the time. This affects both the headlights and the warning lights, but not the tails or gauges. Notice the completely white headlight bucket/frame. The _g texture does not illuminate with the lights: And the warning lights, on their panel, simply stay white constantly - and don't come on when the function is called (currently only using stock functions on them, too) All of these use a dummy material, which I don't have that much experience with using. I may well have done something wrong, but I'm just not sure. Here's their mapping: (each individual rectangle of the warning lights has its own material assigned I've linked a few files to help understand what I've got. I won't link the textures, because it'll give the vehicle away, but I do know that the textures themselves are working correctly at BC7 compression, with colour and alpha mapped, like they should. Thanks.
