Learn how to approach the UE4 shaders in Blender or, if you're lazy, just download them ;-)

I'm modeling a lot of assets for the Unreal Engine 4.

But one problem I had was that I've never knew how the models would look like in the engine. I've build every material twice, one in Blender and then I tried to recreate it in the Unreal Engine which could be a tedious undertaking especially if you use textures for the metallic or the roughness (which differs from the roughness in Blender).

So I've build this shader with the goal that it will look like the shading in the Unreal Engine, and that I could use the same values and textures.

In this video I start going over some of the shader models that are used in the Unreal Engine and point out some similarities. Then I show how to create it in Blender.
