I’d probably use a similar method. model my box or bar, and then fill it with emissive media, skipping the turbulence to give it a more solid look.

The other thing you could try is the looks_like command. The looks_like command allows you to attach an object to a light source. What you would do is create a light that cast on the other objects the way you want. Then, model your box and attach it to the light with the looks_like command. You can then still fill your box with emissive or scattering media so it glows. This gives you a box that is self-illuminated, but will still cast real light on other objects.

Great post and an impressive result!

I would be interested in simulating a very simple situation compared to yours. I want to simulate a glowing rectangle (box), and bar . Any ideas on how to do this. I would like to have a wall near objects which reflects the emission slightly, just to add to the effect that they are actually emitting light.

Cheers,

Dan.
