  1. Begin by opening the image file of the Rhinoceros texture in Adobe Photoshop.[Premium Content - Login] [Membership Options]
  2. Create a new layer by clicking on the New Layer button at the bottom of the layer window.
  3. On the new layer, you will need to create white areas were you would like subtle positive texture and black areas were you would like flat texture. Gray tones will produce intermediate texture results.
  4. Follow Photoshop 1.1 to create a black and white image from your original texture image.
  5. Follow Photoshop 1.2 to adjust the levels of your image. You should exaggerate this adjustment to create a true white and a true black.
  6. If the white pieces of your image are not the pieces you want to be sticking out, click on your primary layer and then navigate to Image>Adjustments>Invert. The blacks and whites of your image will be reversed.
  7. On some textures, the above strategy will not result in proper displacement mapping. If this is the case, you can try the strategy outlined in steps 8 - 12.Cedar shake; 70 inch section of standard cedar shake shingles.
  8. Using the rectangular marquee or polygonal lasso tool (or other similar tool) outline an area to apply a sloping texture. Create a new layer by clicking on the new layer button at the bottom of the Layer window.
  9. Use the gradient tool (often hidden under paint bucket tool) with a linear gradient set from black to white. Draw a line within your selection from the thick part of your material to the thin part of your material.PS-GradientTool
  10. Repeat over each region of your image where you wish to add sloping texture.Cedar shake; 70 inch section of standard cedar shake shingles.
  11. Using the same or other appropriate selection tool (rectangular marquee, polygonal lasso, etc.), select regions that are flat but sticking out (for example the faces of bricks) and use the paint bucket tool to fill them with black.
  12. Repeat for regions that are flat but set back in your texture (for example grout lines in a brick texture), but use the paint bucket tool to paint these regions white.
  13. Navigate to Layer>Merge Visible to make a single layer from your primary layer and your adjustment layers.
  14. Use the Filter>Blur>Gaussian Blur... filter with a 1.0 pixel radius to slightly blur your black and white bump map. This will result in better mapping.Wire screen; 12 inch section of polished square weave metal mesh.
  15. Use File>Save As... and add “_disp” to the file name. Please save your texture and your displacement map in a “textures” folder on your flash drive. You will need these files later.
  16. To apply a Displacement map to a texture in V-Ray, follow V-Ray 8.9 [displacement maps]VR - Map Example - DisplacementVR - Map Example2 - Displacement
