Stone Alpha-izer

Had a quick idea for Substance Painter. A .sbsar that converts any B&W mask to a mask with alpha for use in paint layers. Great for layering on scratches! Demonstration below.

To use, import the .sbsar into Painter as a generator. When in "3" / projection mode, drag it into the input slot and then drag the desired alpha into the new input slot.

Only works with bitmaps, not built-in Painter generators
