Hello Maxwell Render Community!

I want to render realistic neon light.. some photographic examples http://es.wikipedia.org/wiki/Luz_de_ne% ... NeTube.jpg

I found some good results with glowing light bulb done with Maxwell Render and Simulens, but unfortunately no description..

Actually i didn't found any detailed tutorial on Simulens so i would be very grateful for your help.

I tried following: Clear glass material tube with thickness - watertight. Inside of it 5 sides cylindrical emitter, very thin and almost the same length as the tube. Also a plane behind it to visualize the lighting effect. After it rendered for a while i activated scattering in the Simulens tab and tried different values. My Problem is that when i get the desired spread of the gow the whole rendering gets too bright and dull, it looses contrast.. Is there a way to get the glow without brightening the whole rendering so much?

..or completely different solution.. volumetrics perhaps?

Many thanks in advance..

Sometimes the forum search just works
There was a topic about neon lights half a year ago.

yep.. thanks ababak!
I just trust too much google, and there i didn't found anything..
