Unity3d "URP" Implemantation of layered car paint shader. Implementation is based on an old presentation from ATI - https://github.com/gitindro/Unity3DCarPaint/blob/master/ATI-Presentation/Oat-Tatarchuk-Isidoro-Layered_Car_Paint_Shader_Print.pdf
This is not production ready, shader needs clean up. I will clean it up when I get the time.
Use Texture input for Base color instead of Color.
All car assets from from following free asset pack in unity asset store:
