Talk:Real-time Lighting vs Lightmap
I feel the article is slightly off... Personally, I would not nail down "real-time lighting" on the lighting used in editor mode without having compiled a lightmap. This is not to say that real-time lighting is not there, all entities give off such light in real time, like the JP textures or the weapons, items and teleporters... and of course the skybox.
The article does not really mention the actual entities that create the real-time lighting, and that these are also present in the "baked" lightmap. Or why one should use real-time light sources.
