Wetness mask - gradient mask which is based on height and AO. Allows you to dry out a surface with only a height map.
Multi blend - allows you to blend multiple inputs without creating multiple blend nodes.
Curvature Advanced - masks concave and/or convex areas of curvature map with ability of extending, bluring and warping it.
Direction mask - allows you to select and mask specific direction(s) of your surface, for example flat/top/down/left/right through a normal or height map.
Height level mask - allows you to split two height maps and gives you the ability to adjust the height level of one of them and also creates a mask for both.
