Applying Materials to a Surface

How a voxel terrain's material and surface workflows work together.

A graph applying two materials weighted by noise to a surface.

When merging two surfaces using the Smooth Union, Smooth Subtraction or Smooth Intersection nodes, the materials (and other properties applied to the surface) are blended alongside the distance field. The weights are based on the distance divided by the smoothness.

Two brushes being blended with a high smoothness, creating a large transition area.
