I'll try to not post so many updates for this track from now on, but I'm pretty excited about the addition of the LED lights on the thruways. None of the colors are final, but I think they add something extra to the driving experience. I also made the geometric sculpture transparent pink "glass" (I really wish there was a way to make things simultaneously transparent and mirrored in RoR). I also added some actual terrain to one of the straights which can be pretty tricky if not driven through at a high enough speed, which can be seen in the last photo.
Edit: I would like the red LEDs under the finish to change from green to red once driven through -- does anyone know if this is possible?
