Fantastic explanation of Blender lighting
This may be one of the most comprehensive explanations of how Blender handles lights in a scene I've ever seen. I've been using Blender since the 2.2 days and have gotten really used to make all sorts of concessions to make lighting work somewhat normally. I teach an Intro to 3D Modeling course and lighting is one of the toughest things to explain, no matter which program we're using. I'm really impressed by the work you've done and I'm looking forward to the new lighting course. Keep up the good work!
