Deke’s Techniques: Building a sci-fi structure from scratch in Photoshop CS6 Extended 3D

This week’s Deke’s Techniques uses Photoshop CS6 Extended to create an other-worldly structure from nothing but Photoshop pixels. In other words, Deke pays appropriate 3D homage to his alien overlords by building them a temple out of standard earthly linear gradients. The key to building this sci-fi inspired structure is to work in 16-bit/channel mode with a black-to-white basic gradient image. You’ll then use that gradient to create a depth map in Photoshop CS6 Extended 3D. Remember, the white areas will go ‘up’ and the black areas will go ‘down.’

During this free video, Deke explains how to set Photoshop CS6 Extended’s 3D tools to render, turn, repositioning, add a textured surface, and adjust the ground plane for the alien temple you see below. Deke will show you how to load his preset lighting and bring in his textured “alien-crafted brick” surface to use as your materials option. After a few fine-tuning operations (like incorporating the temple into the sandy environment and adding an appropriate acolyte), you’ll have turned this barren dessert landscape on the left, decorated with the basic gradient image in the middle, into the fully rendered alien-acceptable temple on the right:

If you’re a member of lynda.com, Deke also has a member-exclusive movie in the library this week called Drawing a 3D object with Curves in which he uses a Curves adjustment layer to define the contours of a 3D object. In other words, he uses Curves to draw in 3D space.

See you back here next week when Deke returns with a (suitably patriotic) new technique!
