Interior Renders with only 'Artificial' lighting (no daylight HDRI from windows etc.) looking very flat!

For example here at the ceiling I used an emitter. If you disable shadows for the material, than the emitter material isn't used for lighting anymore, but a light behind can illuminate the scene. So, you can use a low intensity for the emitter and the emitter object doesn't look burned out. The light for lighting comes from behind. You can use soft gradient for the emitter textures so that it looks like light sources behind a milky glass.(Not so much used at the example here.)

Advantages are: easy and fast to calculate and no burn out effect.

I cannot find how to disable shadows for the emmiter material. Am I missing something?

You need to add the attribute "raytrace properties" to the material and there you can disable it.

Thank you...I never used that attribute
