Move the new slider all the way down to the bottom and set its value to 0%.-Click on the copy button and choose “all layers”to copy this layer.Step 4:-Now go into the texture editor for specularity, and choose Paste. Select “replace all layers” from the drop down box to paste the gradient you made for the Reflection texture.-Select the top most key at parameter 0 in the gradient bar, and set it’s value to 80%.-Set the bottom key’s value to 2% at parameter 1.Step 5:-Do the same pasting process for Glossiness except enter 30% for the top value key at parameter 0 and enter in 0%for the bottom value key at parameter 1.-Do the same pasting process for Diffuse except enter 58%for the top value key at parameter 0 and enter in 100% for the bottom value key at parameter 1.-Make sure you are able to see the texture window to see what effects your texturing will produce for you when you render.Step 6:-Now go into the color channel and paste in the layers like you have before. Type 3 into the “End Field” box at the bottom of the window.-Delete the lower most key, so you only have one key at the top of the gradient. -Set the color for the one and only key to R. 129, B. 135, G. 150. Make sure it’s alpha is set to 100%-Create a new key below the top one and set it’s parameter to .33, leave the rest of the settings as is.-Create another key below the new one, and set it’s parameter to .82, it’s alpha to 100%, and it’s color to R. 151, B. 97, G. 64.Step 6 cont:-Create a new key below that one, set it’s parameter to 2.66, it’s alpha to 0%, and it’s color to R. 106, G. 53, B. 40.-Create another new key just below that one and set it’s parameter to 2.91, it’s alpha to 42%, and it’s color to R. 209, G. 136, B. 101.Step 7:-Now create 3 keys in the approximate location as indicated by the image.-Select the first of the three keys. Set it’s parameter to 1.75 and it’s alpha to 32%.-Next select the middle of the three and set it’s color to R. 0, G. 0, B. 0. Set it’s alpha to 12%, and it’s parameter to 2.-Finally select the bottom third key and set it’s alpha to 17%, and it’s parameter to 2.25.Step 7:-Lastly select the add layer button and select “Procedural” from the drop down menu.-Set it’s procedural type to Turbulence.-Set it’s color to R. 141, B. 71, G. 71.-Change the opacity to 20%.Step 8:-Go back to the color and bump channels and go to their texture editors.-Adjust the X,Y, and Z values under the position tab for both procedural layers.-Looking at the window with your texture in it, adjust the three different X, Y, and Z values until you have something you like.Step 9:-Render!Gradient color textures and a bump map work great together.This was achieved by doing the following:-Applying a procedural bump map. I used “dented”.-Applying a color gradient for the color channel.-Adjust the values until you are happy!On Your OwnThis one was created in a similar fashion as the one above...except I applied textures to more than just the color and bump channels. Similar to the way the rust effect was created.-Now that you have basic knowledge about textures, you can apply them to something with more realistic.-This was created with a bump map of some shingles, an alpha bump map, and a simple gradient color texture.Helpful Links-Daniel Hirsmuller-Counts:http://www.ecst.csuchico.edu/~ranger/samples/CSCI140/tutorialsF04/danielhc.pdf-Jeff Bohlin:http://www.ecst.csuchico.edu/~ranger/samples/CSCI140/tutorialsF04/Bohlin_tutorial/Tutorial.htm-Patrick Nelson:http://www.ecst.csuchico.edu/~ranger/documents/CSCI140/Spring2004/Gradient_Textures.pdfSummary-Gradient texturing when used with other forms and techniques of texturing can create some very realistic looking objects.-Low render times, depending on models.-Effective for blending colors and other channels together.Thank YouHappy
