Adding an Import masks from RGBA file node
This node creates masks from an RGBA file. The operation is the
same as for importing terrains from an RGBA file and the same file
formats are supported.
This node has four output masks instead of a single one in the
Import mask node.
- The first mask is extracted from the red channel of the texture.
- The second one is from the green channel.
- The third one is extracted from the blue channel.
- The fourth one is extracted from the alpha channel.
To add a node, right-click in the Graph Editor and select Create Node > Import > Import mask from RGBA file.
Double click on the node to open its parameters:
