Roughness map and other

Hi Jonathan how do you create those map (roughness, normal and bump) from just single image? What program? How? Thank.

    Hi Michael, I painted the roughness and bump maps in Photoshop, alongside the albedo map. If you're looking to do this with photo textures, I would recommend trying Allegorithmic's Bitmap2Material program that comes with Substance indie.
