I need help. I've read all the guides, all the tutorials, exhausted the Backroom, but still procedural terrains elude me. Whenever I load up a function, all I get is a patch of terrain full of tall thin spikes that look horrible and jaggy when rendered. I want a procedural terrain full of rolling hills! Rolling hills! Help meee! Thanks -Zak

Which version of Vue? 5 or Infinte? If Infinite, use the function output observer to get an idea of the results of your experiences. I'm no expert on proc terrains, but what I usually do, is start with a simple perlin gradient fractal, connect its origin to a turbulence, try different ones, and combine this to another fractal, this time an altitude voronoi. Then try different blending methods. I found that substract often yields to good results.

Vue 5 Esprit. The graphic preview of the terrain (in the terrain editor) shows a nice hilly terrain, but it actually is spiky and jagged. Thanks, I'll try those different settings.

Hit the Diffusive button a few times with at least 50% softness (or more even). Diffusive is like Gaussian Blur in Photoshop- should smooth those hills down a bit...

Try sizing the terrain in standard mode. Play around in the editor & finally change it over to procedural when all that is finished. When it asks about the adding nodes to terrain, say yes. If that fails then just open up a procedural terrain scene from the extra's disk & tweak it some.

Diffusive did the trick, very cool. Thanks all.
