I'm using Blender 2.77 and I have currently arrived at the native Blender Renderer engine, and I fully want to understand how it works and how I can use, adapt, modify it for my own Blender projects.
I've already read many free e-books, articles and watched many videos about it, but I want to be able to truly understand AND visualize its inner workings.
Unfortunately the official Blender Render manual does not offer much in-depth/under-the-hood insight on how stuff really works, so I still have lots of technical in-depth questions about the Blender internal Render engine like:
QUESTION: - How does BI create "Environment Lighting"?
Is this done by adding just another (hidden) Lamp (like spot, point, hemi, sun, area) to the scene or is it done otherwise?
