There seem to be two kinds of neon-style tube lighting. One where the tube is opaque, like a solid emitter,(I think it might be internally coated with some kind of phosphorescent powder), and one where the glass tube is transparent and the wall thickness is apparent and it contains a soft-edged glowing gas inside.
I'm doing the former right now with an extruded tube as an emitter (with a reflective AGS layer on top in case reflected highlights are visible), but I'd like to try the latter.
Any suggestions?
I guess I need to avoid enclosing a tube-shaped emitter inside a pipe of dielectric glass. So AGS glass?
I haven't played with particles or volumetrics much yet but dare I ask if I can make a light-emitting gas contained in a walled glass pipe?
Obviously there are composite-based solutions, but I'm curious as to rendered options.
