Looking for blog post about custom Paragon development done for LODs

I’m trying to track down a blog post (or maybe a video). It was talking about using Paragon as a case study for features in UE4. Specifically, they were talking about since you have a bunch of high quality hero characters, you need to scale quality based on the number or characters (or elements) on screen instead of the traditional distance based LOD system. The blog post may have gone over other topics, as well.

Does anyone know what I’m talking about or can point me to this?
