On Track 3D Pitboard skinning?

[wattdigger]

I've been able to get the 2D 16 segment pitboard in game that is released on here and MXB Mods, but how do you change the on track pitboard to match? I couldn't find any information on how to change it besides a vague post from Piboso around the time of beta 15 which said to name the texture as w_pitboard for 3D and pitboard for 2D and that they both needed to be packed into a bike paint. This is why its confusing, no definite outline on where or how they need to be installed and the information that is available is conflicting with how current working pitboards are installed (no pnt, only tga, cfg and arr files.)

Exactly where and how do I save/install the on-track 3D pitboard?
