 The most used diffuse BRDF in games. It’s very popular because it’s very cheap to compute and gives good results. This is the most simple way of computing diffuse.  link:https://en.wikipedia.org/wiki/Lambertian_reflectance[here are the details]

-In the <<jme3/advanced/pbr_part2#,previous post>>, I talked about the basics of PBR for developers, and explained the different steps of the lighting process with PBR.

 As said before, PBR does not necessarily imply to have indirect lighting, But that’s what makes it look so good.

 Epic games came with a solution to this issue for Unreal Engine 4. Others did too, actually, but Epic games made it public in this paper, from Brian Karis. I can’t thank them enough for this.
 
- In this link:http://blog.selfshadow.com/publications/s2013-shading-course/karis/s2013_pbs_epic_notes_v2.pdf[paper], they explain how they do it in UE4. They use a method they called the *Split Sum Approximation*. It doesn’t make the computation faster, but it transforms it so that it can be baked in two prefiltered textures.
