Awesome, I'm trying to build a largish river in the middle of one of my maps, with a decent speed to it, I generally learn by video but there isn't much to go off, I'll try these tips (i had just watched the video about the instance painting, and was actually just trying to work with that, but i couldn't figure out how to get a moderate flowing river painted there). Atm I'm just using the large river object and elevations to work it.
