This is because the basic default procedural texture
was applied when you chose Procedural as the Layer Type.
The VIPER preview window has default size of 320?—240 pixels. In Figure 3.19,we??™ve
expanded it to 480?—360 pixels using the Preview Size drop-down. Adjust the preview
window to suit your screen size.When you do so, there??™s no need to re-render your
image.However, if you change scene lighting or object position, or add or remove
objects in the scene, you need to re-render by pressing F9.
15. Because the procedural turbulent noise texture was a little too heavy, change some
of the parameters, such as Size, found at the bottom of the Texture Editor panel
on the Scale tab. Click and drag the X, Y, and Z values and watch VIPER redraw
your image with the surface changes.
16. Experiment with the other procedural type settings such as Underwater or
Crumple. From there, try to use other procedurals and adjust their properties as
well. Figure 3.20 shows the Texture Editor and VIPER with a default Procedural
Texture of Turbulence applied and the Scale made smaller.
Figure 3.20 Changes to texture-property values such as Color, Scale, and Contrast are easy
to see with the VIPER window open.
