Unaltered textures in SketchUp (top) are then rendered (Shaderlight).

Part 2: Textures
Fig. 10.9: 
The same textures from Fig. 10.8 are adjusted in a photo-editing program and 
given greater contrast. The top image shows the edited textures in SketchUp. The bottom 
image shows the textures rendered in Shaderlight with greater depth due to the adjustments.

Fig. 10.10: 
The original texture (left) has its levels adjusted (middle) and then slightly desaturated (right).
Decreasing the contrast can help soften a texture, giving it a more uniform look without 
drawing attention to any single aspect of the material (Fig. 10.11, Fig. 10.12). This might be 
useful on textures like paint, brushed metals, kitchen counters, asphalt, and other materials 
with more uniform and faded surface character. 
Fig. 10.11: 
The Asphalt texture has too 
much contrast (top). It is adjusted in a 
photo-editing program and given less 
contrast (bottom).

Hue/Saturation.
Using Hue/Saturation is an excellent way to create a variety of textures from the same 
material, each displayed in a different color and tone (Fig. 10.13, Fig. 10.14). 
Changing Color 
Adjusting the hue/saturation allows you to completely change the base color of a texture. Black 
granite can be changed to light yellow countertop; red paving can be adjusted to a light gray-
blue. The variations are endless. 
Desaturating 
A common initial result when draft rendering is the oversaturated appearance of some 
materials. Colors can appear overly bright or rich. These values can detract from a rendering. 
Hue/Saturation allows you to tone down a color’s vibrancy. Slightly desaturating colors helps 
moderate the vivid nature of colors in renderings.
