Go to NL Development center and get busters node smoother I use it occasionally but don't use the AHG until the track is as smooth as can be but I still suck at NL so if some one disagrees with my idea go with theirs
I just got finished with my sasquatch coaster! its set in a winter eviroment this coaster has a cartexture so NL track packager!
