After asking a few times unsuccessfully on youtube as to how these fog effects got used in Trainz, I decided to post in the forums. For those who might not understand what I'm asking, I have two links to Youtube for those who wish to view it. First link: http://www.youtube.com/watch?v=6PEIEp0HeTQ And here is the second link, to a different version with real smoke effects. http://www.youtube.com/watch?v=pYs4C99Dy9E the first is a Thomas the Tank Engine remake in Trainz, and the second is an actual episode, Season 5, Ep. 128, for those who wish to look it up. I had an idea to make a route that could be merged with another for a branch line, but I needed the ground smoke/fog/mist effects for it. If anyone could help me out on this I would be greatly appreciative.
