      Looks nice, Rich.

      In reality, the center of each tube would be so overexposed that it would tend to look white, as it is not a surface that glows, but a volume:

      Looks like a "render this" challenge...

          Very interesting material. I must admit emitters, fresnel etc are still something I need to invest time in understanding.
          Here, I think the emitter values are too low... πŸ˜’

            You can also play with darkroom burn value... set larger value and highlights will "burn" towards white (same that happens with low dynamic range cameras).

              Try playing with the radial glare in Thea's post render settings, it will give a soft glow effect.

                Wish I could but I closed Thea after rendering and I don't save .scn πŸ˜’

                I love to know what some of the deeper options do but for now I lurk in their forums hoping to snag the odd nugget of advice.

                  Rich's images to me look like a "correct" exposure for the glowing arcs. The white centers only occurs when an image is over-exposed for the light source. Often this is desirable for night shooting where you want to correctly expose the scene. Doing so often over exposes the light source, thus making them look white.

                  So to me they look right. Perfectly exposed for the light emitter, not the scene around them. And maybe they are mild emitters, like a glow stick, instead of a neon bulb.

                  Have fun playing with it Rich. I love Thea, wish I got to use it more.

                    Thanks Chris. Though the scene itself is pretty pointless it's Notareal's material that has helped me learn much more about Thea and emitters.

                    I could play with Thea all day if I had a better rig. This was an overnight render on my dual core laptop.. πŸ˜’

                      Radial glare is indeed nice if you don't over do it. As it's been a post render effect on Thea, you can easily do multiple versions of image at the darkroom > history

                          Thea can only convert KT scenes when opening one (materials converted by some heuristic). Material systems are too different, so that all Thea features could be implemented in KT.
                          Anyhow, you can still create similar material in KT, you need to use Fresnel ramp procedural as a emitter color. Use bit saturated color as reflectance 0 than reflectance 90.
