Its a shame because most of the vehicles are kind of affected by the dirt mapping not being mapped properly, even making the dirt transparent, will help for the FPIS, but not the charger, i fiddled quite alot with it today, and got no where. The worst part is how Captain14 kind of dissapeared. Hasn't been active in over a year.
afaik the dirt textures are not properly done, it doesn't have to do with the model but more the textures, and it uses GTAV Default Dirt Textures, and as you stated model is locked.. so its rather annoying :(
I'll be honest; this is hands down one of my favorite mods on GTAV; Lighting is fantastic, and just the overall quality of the mod is fantastic! I just wish it has a cage. But thats okay!
Another superb mod by Gump!
