Unfortunately same as how chrome needs the mod set up for it, it needs new material settings punched in. And also some extra files. So, whenever the Monaco's released. Strictly speaking all that I plan to do before releasing it is add some knickknacks (rear view mirror, corner lights, headrest) and texture the whole interior so that might be soon. I'll try to also include some notes on how the new shader works so it can be applied to other stuff easily. Cause it's a bit more than just adding a specular color texture.
Still subject to more tweaks, and when the mod's out it'll probably have a black/black interior. I went outside and meditated (read: stared at a metallic blue BRZ) to figure out what changes the shader needs so this has some subtleness to it the previous screenshots didn't..
