Populate Terrain is a scripted plugin for Autodesk 3ds max. It assists in creating and optimizing terrain surfaces from contour lines or from existing meshes.
The quad based output allows for easier later remodeling, for example using push/pull painting. The regular face size reduces rendering issues (GI, displacement) and you can use Turbosmooth on it. It’s also a lot nicer to look at! The result is always standard 3ds max geometry, so there are no issues with future 3ds max versions, exchanging scene files or using 3rd party renderers.
