Light scattering

I need help in building realistic light scattering in my scene. I have sun light in my scene and some indoor lights.

I want results like in this image… Look how beautifully the light bounces up from the ground from the sunlight and the light scattering from the wall light stripes.

I tried to use the emissive colour option in the material option but it didn’t work at all. It is just creating a light around the object, but it is not illuminating anything…

Please help me to achieve proper results for both of these light effects:

  1. Surface light bounce and scattering
  2. Light scattering from an object and illuminating other objects in range.

Thanks in advance…

you probably need baked lightmaps, if you’re not already using them. emissive materials by default will not light other objects; there’s a setting you can check to enable them to bake lightmaps.

Thanks a ton for the help.
