Configuring Landscape Terrain Details

Details serve to achieve realistic visual representation of the Landscape Terrain in close up views.

See Also#


ObjectLandscapeTerrain stores visual settings for 20 detail masks intended for reaching better level of visual quality in close up views. Details represent arbitrary albedo, roughness and height (displacement) data, so you can drastically improve the look of the landscape terrain. Details are applied according to masks of Landscape Layer Map objects.

If your project requires detection of collisions with the terrain surface, you should keep in mind that Details don't participate in Intersection and Collision Detection, so it's not recommended to apply intense displacement using details since visual inconsistency may appear.

Detail settings available in ObjectLandscapeTerrain parameters allow defining the detail visual appearance, adding up to 1024 details to a mask and defining the material of each detail.

Detail parameters are available on the Node tab of the ObjectLandscapeTerrain parameters.

By combining multiple details under a single mask you can diversify the look of the surface a lot.

The result of combining three details under a single mask.

The list of detail masks displays the hierarchy of details for each of 20 detail masks. Using buttons at the top you can:

  • create details for all selected masks.
  • clone the selected details.
  • move up the selected details.
  • move down the selected details.
  • delete the selected details
Drag details using the mouse to set up the hierarchy, Double-click on a detail or a detail mask to rename it.

Detail parameters allow applying additional masking:

Mask Threshold Threshold starting from which the mask starts to be rendered.
Mask Contrast Contrast of the mask.
Mask by Albedo Select an albedo color of Landscape Layer Masks in the world to be used as a mask. In this case, all areas on the terrain having selected color will be covered by the detail.
Control opacity by using the Alpha channel of the Mask by Albedo color.
Mask by Height This group of parameters is used for mask modulation. For the areas specified by the mask, you can set up the range of heights in which the detail is visible.
  • Min Visibility — minimum height value starting from which the detail mask begins to fade in until it becomes completely visible. The default value is -inf.
  • Max Visibility — maximum height value starting from which the detail mask begins to fade out until it becomes completely invisible. The default value is inf.
  • Min Fade — over this height range below the minimum height value the detail mask will fade in until it is completely visible. The default value is 0.
  • Max Fade — over this height range above the maximum height value the detail mask will fade out until it is completely invisible. The default value is 0.

The Detail Material section contains settings of the landscape_terrain_detail_base material assigned to the current detail.

Internally each Landscape Layer Map stores its 20 masks in 5 RGBA8 mask textures. The following parameters display the info on the corresponding mask texture and can be used to access the mask via API:

Mask Texture The index of the mask texture used.
Channel The channel of the mask texture used.
