Luminance provides tools to use luminance analysis in your materials and blueprints.
With Luminance you get a set of Material Functions and Materials to make it easier for you to work with Luminance analysis. The shipped materials feature cutoff and layer blending out of the box. Also you get a set of assets supporting the new material layering system.
Supports 3 different Luminance standards (ITU.601, ITU.709 and Epic Games' standard).
