This node blends an unlimited number (in practice up to 10) of terrains using the different blend modes available in Instant Terra.
By default, it has three input connectors:
To add a node, right-click in the Graph Editor and select Create Node > Terrain composition > Multi blend.
Double click on the node to open its parameters:
These modes, except for the Mix and Max modes, are the same as
those of the Blend and Full
When a layer uses the Min or Max mode, the color map is not modified, even if the input terrain has a color map.
For example, when blending the following terrains with the "max" mode:
If you want the color map to be updated when blending in the Min or Max mode, you must use one or more Blend nodes instead of a Multi blend node.
If a terrain has a color map, the blending ratio for color maps is the same as for the terrain. Unlike the Blend and Full composition nodes, it is not possible to have a different blending coefficient for terrains and for color maps. If you want to have a different blending coefficient, use a Blend or Full composition node.
The Scale and Reset buttons return respectively to the size of the entire output terrain to the initial size of the terrain layer. They also reset the translation (back to center) and rotation (no more rotation).
