Hi, Am using edit mode to build terrains that are fixed, and that can be tunnelled thru. problem for me is i don't know what variables to set or tweak to have at least some decent control over the creation process. does anyone have some #'s for the different variables available do there is some or alot of control when creating a terrain. I presume this is possible, but too often my hit and miss attempts cause me to restart from scratch. that said, i find this feature in Ruaumoko to be very compelling. kinda like a wild horse that does what it wants.
