Houdini DEM based Terrain modelling

Having used Terragen exclusively for these sorta things I wanted to see if I could replicate some scenarios in Houdini and sure enough it wasn’t all that hard.   Mind you this was just a quick test for what I needed and by far doesn’t encompass all of TG’s functionality.
