The Art of Poser and Photoshop- P10:Before you dive into the first chapter, be sure to download the content and images from . You will see the title of the book in bold and below that, you will find the files you need. Please download the files for each chapter and place them into a main folder named Tutorials. You will be asked to reference the images from that folder as you work through the tutorials throughout the book. Of course you will need Poser Pro and Photoshop CS4 as well | 258 The Art of Poser and Photoshop The Official Guide Figure View of the Granite node added to the X Scale channel 3. Connect to the Bottom channel and notice that only the darker areas in the original texture are affected. The highlights have not been touched. 4. Continue by connecting to the Octaves channel. The Octaves are the denser areas in the original texture. The base color in the Granite node white dominates these areas. 5. Finally connect to the X Scale Y Scale and Z Scale channels and observe how the texture engine attempts to texture tonalities along each of those axes. Applying Photographic Images to Individual Channels Just as you can add procedural textures to individual channels you can also add digital images. In this section you ll add a photographic image to each of the channels. 1. Open another Turbulence node. It will be titled Turbulence_2 by default. Start with the X Scale channel and attach an Image_Map node. To do this choose New Node 2D Textures Image_Map. At the top you will see the Image_Source layer. Click on this layer and navigate to the tutorials folder. Open the file from the Chapter 5 Advanced Nodal Texturing in Poser 259 Tutorials folder. Immediately you can see how the image map is applied to the Turbulence_2 texture. If you observe closely see Figure you can determine the axis that is being affected by observing the direction of the distortion. Poser appears to be allowing it to affect the pixels in a left-to-right fashion which is the X axis. 2. Connect to the Y Scale and Z Scale channels and observe how the texture engine affects the tonalities along each of those axes. Start by connecting to the Y axis and notice that Poser appears to be allowing it to affect the pixels in an up-and-down pattern. See Figure . In this step the pixels that are affected are the ones facing you on the Z axis so everything seems to have some distortion. See Figure . Figure View of the Image_Map node added to the
