You know how on cycles you can have an object set to emit and you can see the glow on the objects next to it? well i seem to remember seeing something about this effect ages ago - using Blender internal. Unfortunately I’m not sure what it’s called, so I can’t really search for it. I mean I could use cycles, but I’m not so familiar with them. What is this effect called so I can search for it please?
Enable ‘Indirect Lighting’ in the World settings and give your objects material an emit value
When is the “Indirect Lighting” setting if one is using Cycles? The World tab has just Use nodes and Color.
