  1. Follow Rhinoceros 5.16 [material properties] to bring up the material properties page.
  2. To add a custom bump (a small scale 3D texture) to a particular surface in your model, click on the “+” sign next to “Bump.” [premium content]
  3. Within these bump settings, you can select a particular image as the map file by clicking on the “…” button. This image file should be grayscale (or black and white) with the black portions representing positive (raised) textures and the white representing flat textures). For help creating a bump map, see Photoshop 1.20 [bump maps].
  4. You can adjust the intensity of the map using the intensity text box. This controls how strong of a relief is created in the bump.
  5. Filtering can help eliminated pixilation in the rendering so generally it should be left checked. If you are tiling a small image on a larger surface, you may want to turn this off so the rendering doesn’t appear blurry.
  6. By clicking on the “Modify” button next to Tiling, you can specify the number of U and V spans that should be done with your particular bump map. Your bump map is 1U and 1V in size so increasing these numbers will increase the number of times your bump map is used to tile over the surface. Your tiling values will generally match the values specified in the texture tiling.
