Adding a Min node
This node takes the minimum value of two terrains. At each vertex, the value of the output terrain is the minimum value of both input terrains.
To add a node, right-click in the Graph Editor and select Create Node > Terrain Composition > Min.
This node has no properties.
Linking to input terrains
Link the Min node to two input nodes.
If both input terrains do not have the same size or resolution, the size and resolution of the output terrain is determined by the size and resolution of the first terrain, and the second terrain is enlarged or decreased so that its size corresponds exactly to the size of the output terrain, before being compared to the first terrain.
For example:
