Adding a Swirl node

Distort a terrain or mask with a swirl effect and set the location of the center of the effect and define the swirl angle to apply.

To add a Swirl node, right click in the Graph Editor and select Create Node  > Terrain Transformation  > Swirl.

Select the node to open its parameters:

Editing a Swirl node

If the input terrain has a color map, then this color map is modified at the same time as the terrain.

Use the sliders or the manipulators to adjust the swirl values.

Right-click to switch between the manipulators.

The Swirl node is only valid for terrains up to 8k x 8k vertices. If the terrain is larger, crop a sub-part of it and apply the swirl on this smaller part.
