Model Terrain With Roads

hey guys i would like to know how is your workflow to create a environment model, with terrain and roads, i would like to make a model detailed but i have a complex topography

Hmm, complexity is a harsh mistress in the realm of SketchUp. Style over substance goes hand-in-hand with hiding crimes. If you’re serious about your topography, I can only direct you to the magical realm of VRay and Lumion. That’s where you get your detailed terrains and environments. I haven’t used either of them myself, but the results are nothing shy of breathtaking in the right hands.

As for the home court advantage, my method is extremely crude, time-consuming, and probably not worth the effort unless you’re also willing to go full Pro and brave the untamed wilderness of the Extensions market. Here’s a recent example I’ve been working on for a project: BrutalBenchone
As you can see, nothing special, and when I show you the “X-Ray” perspective, you may want to rethink your life choices, as I know I do far too often.


The breakdown in a nutshell.

  1. Make a grid (squares, hexes, triangles, etc.).
  2. Start grabbing points or edges.
  3. Give ‘em the ole’ heave-ho with the Move tool.
  4. Smooth or hide as necessary with the Eraser tool.

Like I said, there are better ways to do this, most involving Extensions. This is just my workflow, used very sparingly, and typically in conjunction with another program (like a 2D painting program, taking advantage of the PNG’s alpha channels and the perspective lines). Your best bet may be a divide-and-conquer strategy, one program for the vehicle, and another for the terrain.

Vali architects extensions are a godsend for roads on terrains

Well worth the investment if you are doing large site developments

40 hectare steep site with public and resort roads, colours map to Twinmotion for auto generation of soft landscaping types… eg grass


, pine forest, road verges etc

Twinmotion 2018 render, current TM is much more capable
