Liveries are a feature you can apply body wide decals to your car paint. You can use the original decals or change the decal color to one color of your choice. I added the option to support transparent and greyscale decals. In order for your decals to work with 90% of the models on the market this feature needs UVs to work. I included a smart UVW system with the plugin but it is best to UV your models then use any texture paint software to make the 2D decals and assign them accordingly.

In order to keep things as open and forward thinking as possible. The toon materials require lots of tweaking to get the desired results. I included matte layer testers in the plugin, please use these layers
