So I have a custom tacho DDS already made, and I have the materials.cs pointing to the new tacho. The problem I'm having is that both the old and new tacho appear on all models of the car, not just the ones I want it to appear on. 1. How do I set it up such that only the models I want to have a custom tacho? 2. How do I prevent both tachos from being loaded in? I have attached a ZIP folder containing all that I've done for the vehicle.
