In this example, the Noise tool is used to paint on the Landscape, similarly to how Sculpt would be used, and in doing so variations are painted around this area that raise and lower the heightmap based

Use the following controls to Sculpt with Noise for your Landscape heightmap:
Left Mouse Button
Heightens or increases the heightmap or selected layer's weight.
