So what sort of material spec would you use to model glowing neon light tubes? I've fiddled with emissivity, but that doesn't seem to be a true light source...

Thanks,

Hi,

For a linear neon source you can use area light attached to an emissive cylinder to simulate the neon tube, as in the image below.

For more complex form factors (letters), I think I'll use area light panels with some masking tricks...
