Definite progress.
What does the snow effect look like without the engine smoke particles? Can that effect be lessened if desired?
Also, is there a way so that trees and objects don't cast shadows when it snows?
Thank you very much for experimenting with this. The poor precipitation effects in OR have been one of my strongest dislikes.
The first problem is that the precipitation box seams not to follow the trains axis but is locked to a compass direction, so with settings like mine above, only south/north or properly reversed travel gives snow in front of a fast moving train, going East hits the narrow edge of the rectangle. Making the box square is producing to many particles and strain the cpu/gpu to much.
Changing the snowflake.png texture only, gives a good effect when Reshade motion blur is enabled, looks too rough/sharp when not using that. See attached picture with it enabled.
The ideal solution I think would be two precipitation boxes one large with patches of snowflakes, the other a small one close to the train with only single flakes particles.
Unlinking it from the diesel smoke system and throttle settings, and getting dedicated emitters would be needed for this to be more than a demo, that only works at high speeds and special lighting/haze settings and only work on diesel trains.
Sometimes the Sun and shadow look great in snow, but Ii think the shadows intensity and sharpness should be linked to the visibility/haze/cloud cover settings so it's off in a blizzard/foggy/Heavy rain condition.
