This node changes the size and resolution of a terrain.
To add a Change size node, right click in the Graph Editor and select Create Node > Terrain Transformation > Change size.
Double click on the node to open its parameters:
The Current size in the parameters dialog displays the current Terrain Width and Height in meters and the Quad size of a grid quad.
Link the Smooth node to an input node.
The size of the terrain is divided by 2 and the Scale heights accordingly parameter is selected. The output terrain is a smaller version of the original terrain.
In this example, the size of the terrain is divided by 2 and the Leave heights unchanged parameter is selected. The output terrain is smaller but the mountains have still the same heights; now they are sharper.
|Width||New width (in meters) or the scale factor (as a percentage) to be applied to the width|
|Height||New height (in meters) or the scale factor (as a percentage) to be applied to the height|
|Quad size||New size (in meters) of a grid quad|
|Absolute values||Defines the values of the new dimensions of the Terrain in meters|
|Relative values||Sets the scale factor to be applied to the dimensions of the Terrain as a percentage|
|Keep aspect ratio||If selected, the width to height ratio is constrained|
|Scale heights proportionally||The scale factor applied to the width and the height is also applied to the heights of the vertices so that the terrain remains with the same look.|
|Leave heights unchanged||The heights of the vertices are preserved|
