Getting Started Guide (Version 1.10)

Adjusting Terrain Height

After you paint your terrain, you can manipulate its height with the Modify Terrain settings.

The Modify Terrain section includes brush settings and noise settings.

Brush Settings

Use the following settings to adjust the rise/lower, smooth, and flatten brushes.

  • Flatten – Flatten the terrain to the preferred height setting.

  • Smooth – Soften the terrain down to a smoother surface.

  • Rise/Lower – Raise or lower the terrain based on brush size settings.

  • Pick Height – Find and set height based on existing terrain geometry.

  • Outside Radius – Set brush size for painting.

  • Sync Radius for all Types – Set the same outer radius value across the flatten, smooth, and rise/lower brushes.

  • Inside Radius – Set how round or flat the brush is in relation to the outside radius setting.

  • Hardness – Soften or harden the outer brush settings.

  • Height – Set the brush height.

Noise Settings

Use noise settings to add random terrain variances to the brush.

  • Scale – Modify the strength of the noise effect. Higher values produce more noise.

  • Frequency – Set how often the effect is applied.

The following procedure shows you how to create a range of hills and mountains.

To modify terrain height

  1. In the Rollup Bar, click the Terrain tab and then click Modify.

  2. Under Modify Terrain, click Rise/Lower and use the following settings to create gentle hills in your scene:

    • Outside Radius = 25

    • Inside Radius = 1

    • Hardness = 0.25

    • Height = 3

  3. In the Perspective viewport, navigate towards the outer perimeter of the terrain map and click or drag to paint on the terrain. Experiment with clicking and dragging along the terrain to manipulate the terrain to different heights. Build some larger hills of different sizes and shapes.

  4. Modify the brush settings to the following:

    • Inside Radius = 20

    • Hardness = 1

    • Height = 1

  5. Paint again on the terrain. Notice how the terrain rises up straight and rigid.

  6. Click the Smooth tool and use the following settings:

    • Outside Radius = 25

    • Hardness = 0.2

  7. Paint with the smooth brush over the last area of terrain you created. Notice the smoothing of the terrain.

  8. Click Pick Height and click on a high point on the terrain. Notice that the Height setting in the tool adjusts to the height you clicked on.

  9. Select a point on the terrain where the height was unchanged. The Height setting in the Modify Terrain tool changes to 32 (the default terrain height). This tool does not affect your terrain directly but simply adjusts settings for the next step.

  10. Click Flatten, and use the following settings:

    • Outside Radius = 25

    • Inside Radius = 0

    • Hardness = 1

  11. Paint with the Flatten tool over the area you just smoothed. The terrain flattens to the same height as the rest of the default terrain height.

  12. Using the terrain height tools, create a range of high and long hills that vary to create visual interest.

  13. Use the Smooth tool to soften where you like. With time and experimentation, you can make your terrain look like the following picture.

  14. Save your level file.
