This is what Lincoln says about his Master Material:

After looking online to see what there was out there for materials in UE4, I came to the conclusion that there just isn’t really that much. You can buy textures, you can buy material functions that help you make your own materials, you can buy packs of assets that have their own master materials (with next to no explanation as to how to properly use them), but you can’t just buy a Master Shader that has all of the functions you want to be built into it, all in a tight little bundle that’s easy to use, and quick to set up.

Using the material editor in UE4 can be really complicated. Especially for those who are just getting started with the program, or those without a background in tech-art, or programming. I’d imagine that trying to decipher some of those spaghetti noodles can seem as daunting as translating ancient hieroglyphics!

The whole purpose of the Master Material pack was to remove that element of complication; to empower the average user with the same shader functions as any AAA game-studio.
