Creating a 3D Bump Map in Photoshop

Create a 3D Bump Map

You might have heard that Photoshop “does 3D” now. Many of us have heard the rumor, but have yet to see it in action. In this free episode of Deke’s Techniques, Deke provides a demo, performing a task uniquely suited to Photoshop: creating a 3D bump map in Photoshop and applying it to 3D objects. He transforms an image into a repeating tile pattern that can be wrapped (aka mapped) around the body of a rocket ship—a model he created completely from scratch in Photoshop. He shows how to assign the texture to the rocket layer, render the scene to test the map, and resize the pattern to fit the object properly. In the end, you’ll have a realistically textured 3D surface.

One tiny problem: The rivet texture also appears on the ship’s window. Members can visit the lynda.com library to find out how to paint away extra texture with the brush tools. (Yes, you can paint directly on 3D objects in Photoshop!)

Next week, it’s all rainbows and sunshine! Stop back by for another free video and learn how to use rainbow gradients and lens flares to add reflections to the surface of the ship’s window.

Learn it from the experts.
