Umajin has new PBR lighting model. Physically based rendering or PBR is a shading model in computer graphics that seeks to render graphics in a way that more accurately models the flow of light in the real world.

Basically, you get to decide the lighting information for each pixel, its shininess, its roughness, its color, its occlusion. The underlying shader models the materials microsurfaces and how they reflect, absorb and scatter light.

Here is a video of some sample PBR models loaded into Umajin.
