UE4 PBR Validator Blueprint [4.18.x]

What does this do?

It validates if the values used in a PBR environment make sense. There are certain rules that have to be met for your scene to look realistic, this simple blueprint checks for these rules and colours your scene accordingly.

The result of this is comparable to what you get when you verify PBR in a package like Substance Painter. It just allows you to use it on your entire scene and look around to closer inspect the values. 

How to use?

Simply drop BP_PBR_VALIDATOR in to your level and enable it in the actor settings.

Basecolor Mode: Checks for non metallic values within tolerance.
Metalic Mode: Checks for metallic values within tolerance.
Combined Mode: Both of the above. (duh)
