Cartoony Terrain

I was wondering if I can take a realistic terrain that you can find on the market place and make it look cartoony. (Think of a Borderlands/ Diablo kind of feel) Or do I have to make terrain already like that? If so do I use world machine or is that a job for a 3d artist? Thanks!

It’s really the textures, materials, and post processing that makes a terrain look like something from Borderlands or Diablo, so you should be able to easily take an already existing terrain and modifying it to get that look. You will probably need to edit the textures though, so hopefully you are comfortable enough with Photoshop to tweak those to look more hand painted.
