The MR Lighting Tools is a Unity library and MRTK extension that estimates and replicates the current environment's lighting on additive displays to increase immersion in mixed reality. It works by using physically based rendering techniques to shade 3D objects based on the normal, texture, and estimated lighting captured from the environment's cameras, though cameras cannot fully capture how lighting appears to the human eye. The library is available from Microsoft and the developer hopes to expand it to include shadows and better account for room size to further improve immersion.
