OK, i figured out the problem. You know you are putting WAY to much JVC grass down when you copy and paste a 8X8 segment and it really lags, on a 1 baseboard route. It looked realistic but my trainz now wont even load the route lol. Time to start over. At least it was at the beginning of the route and not at the end. BTW does anyone have any good tips on putting dried grass down without killing your route?
