Affecting Visibility

Brushes may also affect landscape visibility - can make holes in the landscape.

In order to use this feature, you first need to modify the Landscape Material to add support for visibility:

  1. Open the currently used Landscape Material
  2. Change the material type to Masked
  3. Sample the Landscape Visibility Mask (this is the one to which our brushes write)
  4. Output the visibility value as Opacity Mask (either in the SetMaterialAttributes node or in the Result/Output node)
  5. Select the Landscape actor and reuse its landscape material as its Landscape Hole Material
  6. Select all of the Landscape Streaming Proxies and reuse their landscape material as their Landscape Hole Material

Once the landscape material is applied, configure the brush to affect the visiblity mask.

For dark input textures, increasing the Scale Z/Multiplier may be required. Alternatively, Opacity Mask Clip Value property in the Landscape Material can be decreased.
