Use case - Normal map

This sample extracts and exports a normal map from composed terrains. It computes the normal map to be able to add surface detail such as bumps, grooves, and scratches to a model that catch the light as if they are represented by real geometry.

• The terrain composition group sums two terrain generators, one of which is linked to a rock erosion simulation. Two consecutive Add nodes then link to the normal map export and the normal map visualization.

• The Compute normal map node is linked to an Export vector map node, which exports the normal map as an image.

• In order to view the Normal map, we can import a color map and apply it to the composition.
