Here's some more greebles with Anything Grooves. This time I made tileable maps in photoshop for the bumps. The top one is a single 64x64 square tiled seamlessly. For the bottom one I used that same 64x64 square, and another one, which I duplicated and rotated to fill a 256x256 square. I used the same maps along with the color gradient function to control the color and glow channels. Tomorrow I'm going to try some Anything Grows Greebling......
