Adding an Import mask node

This node creates a mask from an image file. The operation is the same as for importing a terrain and the same file formats are supported. The mask is filled directly from the image gray scale (no scaling).

To add a node, right click in the Graph Editor and select Create Node  > Import  > Import mask from file.

Double click on the node to open its parameters:
