[Substance Painter] Emissive Greyscale for Base.

oXYnary

How would I setup a project to use a grayscale emissive to then use the Albedo/Base as the color to make emissive?

If I attempt at this time to use the standard pbr shader and the emissive grayscale, it changes the entire object to a bright yellow.  Does this require a custom shader to pull off?

Yes, you'll have to derive a custom shader from the shipped ones.
