Usually in scene I leave a few lights turn on, I'm making an exception for this time. Turn on maximum points that provide uniform coverage in scene. I think you can set up scene yourself as you need. I think this is the last environment.
If your GPU is powerful check the Pixel Light Count item...
Like these screenshot, the build-in neon light will go through hairs, like it's on upper layer than the hairs while rendering.
Even though it's just a small flaw, it will feel better if I can fix it.
Is anyone have a hint about this?
Thanks!
