AS Flood Fill Auto Levels - Substance Designer Custom Node

A free custom node for Substance Designer that remaps the grayscale values in an input image per shape to use the full span of grayscale values from 0 to 1 within the shape, where the darkest pixel is 0 (pure black) and the brightest pixel is 1 (pure white). Requires a Flood Fill Bbox, Special Shape Info, and texture input.
