Using Terragen Classic with Sim on a stick

Sim on a stick gives you 4 regions in a 2×2 layout. The land however is a featureless 512x512m expanse. So you want to have something more interesting, but don’t want to manually terraform it all? Enter Terragen Classic!

Terragen

  1. Create a New World from the World File menu.
  2. Open the Landscape window, then click the Size button.
  3. Set the Terrain Grid Points to 513 and the metres point spacing to 1 (this should indicate a terrain size of 512 meters), then click OK
  4. Click the Generate Terrain button in the Landscape window, then select Generate features on existing terrain.
  5. At this point you can click the Generate Terrain button in the Terrain Genesis window a few times with the different options, or just click it once then edit it later via View / Sculpt.
  6. Click the Close button in the Terrain Genesis window, then click the Modify button in the Landscape window.
  7. Enter the height range as being from 0m to 256m, click the Set Height Range button, then click the Close button in the Terrain Modification window.
  8. Open the Water window, set the Water Level to 20 then click the Update Maps button.
  9. At this point you can edit the terrain by clicking View / Sculpt in the Landscape window, or preview the terrain with the Rendering Controls and 3D Preview windows.
  10. In the Landscape window, click the Save button, making a note of the location where you saved the file.

OpenSim

  1. Open your RegionConfig.ini file in a text editor, and make a note of the Location property for the south-west region (in this example it is Portable1 1).
  2. Bring up the OpenSim console.
  3. Using the location you saved the terragen file to earlier and the Location of the south-west region (3272 5924 in the example), you’ll need to enter something like the following into the OpenSim console (see Server Commands on the OpenSim Wiki for documentation of this console command): bash change region Portable1 1 terrain load-tile "C:\Users\Foo\My Documents\test.ter" 2 2 3272 5924 change region Portable1 2 terrain load-tile "C:\Users\Foo\My Documents\test.ter" 2 2 3272 5924 change region Portable1 3 terrain load-tile "C:\Users\Foo\My Documents\test.ter" 2 2 3272 5924 change region Portable1 4 terrain load-tile "C:\Users\Foo\My Documents\test.ter" 2 2 3272 5924

  4. At this point, you may notice that the terrain textures look a little off, but if you try changing the Ground Textures in the Region/Estate window, it only applies to the south-west region regardless of which region you’re in.
  5. Although there’s an option that requires editing the config files, we’re going to use the OpenSim console to set the ground texture heights. You’ll need to refer back to the Location of all 4 regions from RegionConfig.ini (see Server Commands on the OpenSim Wiki for documentation of this console command): bash set terrain heights 0 20 256 3272 5924 set terrain heights 1 20 256 3272 5924 set terrain heights 2 20 256 3272 5924 set terrain heights 3 20 256 3272 5924 set terrain heights 0 20 256 3272 5925 set terrain heights 1 20 256 3272 5925 set terrain heights 2 20 256 3272 5925 set terrain heights 3 20 256 3272 5925 set terrain heights 0 20 256 3273 5924 set terrain heights 1 20 256 3273 5924 set terrain heights 2 20 256 3273 5924 set terrain heights 3 20 256 3273 5924 set terrain heights 0 20 256 3273 5925 set terrain heights 1 20 256 3273 5925 set terrain heights 2 20 256 3273 5925 set terrain heights 3 20 256 3273 5925

You should now have a more interesting 512x512m expanse to look at! Familiarise yourself with View/Sculpt window in Terragen Classic or start terraforming with your viewer tools to create a more navigable terrain.
