Hmm. tried it but it didn't do anything. Basically, you ever seen pictures of a comet? They have the ice and stuff just in front of the comet being blown back in a convex shape. I know you can't rotate the lake object, not yet at least, but you could do it on terrain. Trouble is you can only seem to dig straight down into the terrain, or you use negative displacement to go upward. there's no horizontal displacement. Would the techniques used in renders like climbing the chimney work?
