CEL (Citigen Environment Lighting)

THIS MAY REPLACE ALL YOUR NEEDS FOR OUTDOOR ENVIRONMENT HDRIS.
 
Blender comes with powerful built-in procedural environment setups. Few, however, know how to utilize its full potential. With CEL (Citigen Environment Lighting, a part of the Citigen addon), you can do just that. CEL may be the first addon that provides a "usable" 360-degree procedural volumetric sky to Blender users.
