Book description

Finally the eagerly-awaited next edition of Luke Ahearn's cornerstone game art book: 3D Game Textures is on its way. The book will be refreshed per the latest revision of Photoshop and the latest game industry trends and developments. 3D Game Textures allows next-gen game artists to learn to create everything from bricks to books in Photoshop with this step-by-step instructional guide. Because texture is 99% of what a gamer sees when playing, this topic deserves considerable coverage but has gotten little attention. Unlike anything on the market, this book concentrates soley on texturing, and provides an in-depth guide to game texturing with hundreds of high-quality examples. Game artists learn all they need to know on the topic, including basic artistic principles, tools and techniques, and specific step-by-step tutorials that explain how to create textures for myriad environments. New Coverage of the latest version of Photoshop, including adding multiple edge tiling; adding Photoshop Bridge coverage; an updated metal tutorial and adding coverage of urban exteriors. Included in the second edition is a new chapter and an advanced project, featureing a large outdoor urban area - war torn city. Great amount of work on detailed textures (overlays and advanced blending in PS) that utilize many shaders. This environment will look roughly like Battlefield 2 or more recently Call of Duty 4. The scene will include effects as well - smoke and bullet holes. Grass, trees, curtains, signs, and more. The DVD includes: demo versions of relevant software as well as resource images.
