I have my blend file at pasteall.
Whenever I try to render the scene with no render layers selected, it says
All render layers are disabled and then does nothing. This is as it should be.
However, whenever I try to render the scene with any render layers enabled it seems to utterly ignore the render layers and render whatever is visible in 3D view instead.
Better yet, the point light I've put in does . . . nothing.
I'm actually working on a real piece, and I did this experiment in parallel with it (I want to do some symbolic artwork about the internet/information exchange using Blender.), and I'm afraid of something like this happening to actual work.
Thank you very much to anyone who can illuminate this!
P.S.: I have this idea working in several other blend scenes, it's just this one with which I've made a problem for myself.
