Needed a pattern for a character's scarf, got stuck trying to create the pattern in Photoshop alone; and Illustrator is not my best thing.
Started in Maya, took a polygon plane, and rotated it 45 degrees, RMB to select faces, assigned a new Lambert to every other face. Took a screen shot and opened it in Photoshop. Had to use Edit-Transform-Scale and stretched it vertically to get the diamond shape. Duplicated the layer and reduced the opacity, moving it over to get the diagonal patterns. Had to experiment with Image-Adjustments-Hue/Saturation and Brightness/Contrast. Try it, you'll like it!
