Here I've used your file, set a simpler material, and played a bit with the different values of CrazyBump, it gives a bit of blur and grey, you can get something better than what you can get with a simple B&W picture, but you can't simulate a deep engraving, especially if you don't have any image texture that goes along and that could help to fake it. This is normally felt as a hard painful lump which is the size of a small pea under skin on side of nose. Perhaps as a boil, where one of nose hairs has been pulled and thus the dead follicle is then infected. Play with the Strength value of the Bump node to increase the effect.Īs Cegaton said, if necessary, you can increase the effect with a Converter > Math node ( Multiply mode) between the Image Texture and the Bump (you could also try a Converter > ColorRamp node between the Bump and the Diffuse). Lump on nose appears like one of hair follicles that are inside the nose which is infected. Then: Image Texture node ( Non-Color Data mode) -> (Color Output) -> Height input of a Bump node -> Normal input of a Diffuse node -> Material Output node. At first of course, use an app like CrazyBump or else to convert your picture to a DISP picture.
