The javafx.scene.effect.BlendMode used to blend this individual node into the scene behind it. If this node happens to be a Group then all of the children will be composited individually into a temporary buffer using their own blend modes and then that temporary buffer will be composited into the scene using the specified blend mode. A value of null is treated as pass-though this means no effect on a parent such as a Group and the equivalent of SRC_OVER for a single Node.
