Automotive Materials Pack

If you use Unreal Engine, chances are you’ve used the highly popular and free “Automotive Materials Pack” provided by Epic Games in their marketplace/FAB. It’s a highly flexible and dense library of shaders, with tons of customization options, and boy do they look great. If you see a car rendered in Unreal Engine on youtube, the artist is most likely using these materials.

I use these shaders so much, it started to become an issue that I didn’t have access to a similar set of materials outside of Unreal Engine, and since outside of the real-time context I am a big Houdini fan, I thought it would be a good idea to try building some shaders in MtlX for Karma rendering.

The MtlX Version

The node graph beneath the master materials in Unreal is rather dense, but I broke down some core components I wanted maintain for Karma rendering.
