The bussards are about where I want them now. Or at least, I’m done fiddling with them for now. I redid the lights and played around with the dome settings. The dome itself has no glow, all of the light comes from the inner bulbs, just as it should be.
Here’s a look at it without the dome in place and with the emission shader turned way down so that the lights don’t blow everything out.
Yes,there are only two colors of lights here. Also, my dome is tinted orange. It doesn’t look like the bussards on the Enterprise from the original TV show and it’s not supposed to, because I’m not building the original Enterprise. I’m building something else. And, since this is done, (or at least as done as it will be for now) I can get on with the rest of the ship.
