This sample demonstrates how to create the sandstone buttes
found in Monument Valley.
The Painted mask
node is used to trace the location of a road on the terrain. You
can also export the mask to use later or in another project.
The mask composition combines two Painted masks to bring more
precision to the scattering. The Mask scattering group uses a
Painted mask to drive the distribution of the rock on the
The base of the terrain is formed by terrain generators,
composers, and transformers, and a mask composition node.
The Painted mask drawn at the start of the project is linked to
generate a flat terrain base where the road passes.
curve node creates the buttes in our terrain, specific to
The clamp mode of the Min &
max heights node creates a slice at half the height of the
rock. This allows smoothing of the lower part to simulate an
erosion effect on the embankment before recomposing it with the
This group generates a mask from the terrain slope to avoid
forming the road over a terrain that is too rough.
The final composition composes the base of the road and the
reworked rock base.
