Title: Realistic Mountain Ranges (Very small scale)
Post by: Kivak on February 04, 2016, 09:20:03 PM
Hi all,

I have seen several WM maps with mountain ranges like these but I have not yet figured out how to make them. Can someone give some hints as to how to make mountain ranges like these? They look like fingers with long valleys and ridges.

Best way to get these is to find a similar DEM, convert it to heightmap using 3dem, import to worldmachine and refine.

Interesting... so there isn't a way to make these structures procedurally?

Of course there is. But time consuming, and I've never tried before. This way is faster and gets the job done.

That real-world example is defined by heavy erosion of a relatively featureless mountain uplift (orogeny).  You may or may not be able to reproduce the effect in WM directly at the final scale you want.  You may have to do your WM modeling at a larger scale for the WM erosion node to give comparable results, then scale the results down afterward.
