Hi all, I thought Mist or Fog like enviromental conditions should give us a nice 3d light effect on the locomotive especially. It's a real effect in real life where light illuminates the particles in the air that are suspended there for longer periods of time. For rain, snow we should still see a "light" 3d light effect as the light would reflect off the water droplets or snow particles. A small but valuble feature. They have this in Miscrosoft Flight sim and it dose make a diffrence, massive diffrence two withouth much performance sacrifice.
