This node creates a circular cone-shaped terrain. The height of the vertices are impacted from the outside to the center, radially. The terrain's profile is edited by a curve.
To add a Circular symmetry node, right-click in the Graph Editor and select Create Node > Terrain Generation > Circular Symmetry.
Double click on the node to open its parameters:
You can set the minimum and maximum height of the vertices to a defined value, represented by a value of 0 and 1, respectively, on the curve.
By default, the Manual curve editing mode is activated.
Using the smallest cursor makes detailed changes to the values; using a larger cursor makes changes to larger areas in the circular symmetry.
Click on the Smooth button to smooth the values of a curve. You can click several times to smooth more.Smoothed curve
Once you have edited your curve, you can switch from the Manual mode to the Point mode to add control points. The control points are displayed in increasing subdivisions of five, from 5 to 50 points. A higher number of control points gives you more control over the changes you make to the curve.
The Automatic point editing option is selected by default. This option does not use anchor points:
If you have not yet edited your curve in the Manual mode, you can click on the curve in the Point mode to add and edit points.
To delete a control point, right-click on it and select Delete this control point in the contextual menu.
Click on the Reset button to reset the curve to the default values.
