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:
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.
|Rotation angle||Rotation applied to the terrain in degrees (default value 30°).|
|Translation along the X axis||Translation of the rotation center along the X axis (by default 0, at the center of the terrain).|
|Translation along the Y axis||Translation of the rotation center along the Y axis (by default 0, at the center of the terrain).|
