the Render Option dialog box in the 3D menu.
Quality
The Quality options set the display quality of the 3D object. You have to set
the quality level in order to maintain both display quality and optimal
display resources performance. The Quality options are interactive: these
include Ray Traced Draft and Ray Traced Final. The Ray Traced options
provide better quality, and some efects are supported only in the Ray Traced
options, such as shadows and lights. The Ray Traced option is considered the
most important and the most commonly used render quality method that
provides high-quality rendered output. This rendering quality setting is
recommended for a high-quality model look.
You can always choose Ray Trace Draft or Final to see how the model will
look like after exporting or inal render. However, choosing these options will
render the model using the Ray Trace method, which takes time to load and
calculate the shadows and light. If necessary, you can stop the render
process by clicking the on the stage.
Because the Ray Trace is considered one of the most important rendering
methods in Photoshop, there is a section in the 3D tab in the References
dialog box that contains options for the Ray Tracer threshold. This section
provides a High Quality Threshold slider that lets you set the highest quality
that the Ray Trace render can reach before it stops the rendering process.
Using a lower threshold value will let the render stop while rendering
information in the model such as shadows and light.
Paint On
As discussed with painting and texturing in Chapter 8, the Paint On options
set the texture map that you will directly paint on the model. For instance,
you can set the Paint On option to Difuse if you would like to paint on the
model and change its colors using any painting tool. Or you can set the Paint
On option to Bump to change the polygon surface depth.
Global Ambient
The Global Ambient color represents the global color that relects on the 3D
model and its applied texture. However, changing the ambient color afects
the environmental color applied to the model. To change the ambient color,
click the color sample and change the color.
Cross-Section
The cross-section slices the 3D object using a plane into two sections on the
X, Y, or Z plane, according to the plane's position. The result is part of the
