Textures and 3D Painting
Texturing and painting the 3D model is the second step after creating the
model itself. Although the 3D polygon mesh has one solid color, in real life
most models have texture and map efects applied to them, which helps
create more realistic efects and higher rendering quality.
In the previous chapters, I covered how to import 3D content into Photoshop
and how to create 3D content from scratch using 2D layers or built-in 3D
content. When you create 3D content based on a 2D layer—such as
postcards, built-in 3D objects, and 2D grayscale layers—the 3D model
created uses the 2D layer as a texture or map for the created object.
You can also create 3D content based on a blank layer; in this case, there will
be no texture applied to the 3D layer, as Photoshop does not have anything
to use as a texture reference. The texturing and mapping extends to cover
not only materials added to the object, but also the object's polygon by
bumping areas and afecting the light texture, as we will see in this chapter.
Photoshop provides additional tools to enhance your model's look and
texture by allowing you to paint and draw over the 3D model. The same
tools that you used to paint and draw over the 2D layers are now able to
