Reveal surfaces to paint on

Set the paint falloff angle

Identify paintable areas
You can use any Photoshop painting tools to paint directly on a 3D model just as you would on a 2D layer. Use selection tools to target specific
model areas or let Photoshop identify and highlight paintable areas. 3D menu commands let you clear away areas of a model to access interior or
hidden portions for painting.
When painting directly on the model, you can choose which underlying texture map to apply paint to. Typically paint is applied to the diffuse
texture map, which gives a model material its color properties. You can also paint on other texture maps, such as the bump map or opacity map. If
you paint on an area of the model that lacks the type of texture map you're painting on, a texture map is automatically created.
1. Use the 3D position tools to orient the model so that the area you want to paint on is facing forward.
If the model area is hidden, you can temporarily cut away surface areas that are blocking your view. See Reveal surfaces to paint on.
If you are painting on curved or irregular surfaces, you can get visual feedback before you paint of which areas can best receive paint. See
Identify paintable areas. You can also set the paint fall-off angle, which controls the amount of paint applied to angled surfaces. See Set the
paint falloff angle.
2. Do one of the following to set the texture map to paint on:
Choose 3D > 3D Paint Mode, and select a map type.
In the 3D panel, select the Scene panel. Choose a map type from the Paint On menu.
If you try to paint on a texture map type that the material doesn't contain, Photoshop prompts you to create a map. For information on map
types, see 3D Materials settings (Photoshop Extended).
3. (Optional) Using any selection tool, create a selection on the 3D model to restrict the area that you want to paint on.
4. Apply paint using the Paintbrush tool. You can also use any other tool in the second section of the Tools panel, such as the Paint Bucket,
Smudge, Dodge, Burn, or Blur tools.
While painting (after completing a stroke), you can view the effect of the painting on the texture map itself. Do one of the following:
Double-click the texture map in the Layers panel to open it.
In the Materials section
menu icon for the texture map you're painting, and choose Open Texture.
Reveal surfaces to paint on
For more complex models with interior or hidden areas, you can hide sections of the model for easier access to surfaces you want to paint. For
example, to apply paint to the dashboard of a car model, you can temporarily cut away the roof or windshield, then zoom inside the car to get an
unobstructed view.
1. Select an area of the model that you want to cut away, using a selection tool such as the Lasso or Marquee tool.
2. Use any of the following 3D menu commands to reveal or hide areas of the model:
Hide Nearest Surface hides only the first layer of model polygons within the 2D selection. To quickly peel away surfaces of the model, you
can use this command repeatedly while keeping the selection area active.
When hiding surfaces, rotate the model if necessary to position surfaces so that they are perpendicular to your current view.
Only Hide Enclosed Polygons When selected, the Hide Nearest Surface command only affects polygons that are fully within the selection.
When unchecked, it hides any polygons touched by the selection.
Invert Visible Surfaces Makes currently visible surfaces invisible, and invisible surfaces visible.
Reveal All Surfaces Makes all hidden surfaces visible again.
Set the paint falloff angle
When painting on a model, the paint falloff angle controls how much paint is applied to a surface as it curves away from the forward-facing view.
The falloff angle is calculated based on a "normal", or straight line projecting out from the part of the model surface that faces you. For example, in
a spherical model such as a soccer ball, the falloff angle to the exact center of the ball as it faces you is 0 degrees. As the surface of the ball
of the 3D panel, select the material for the area you are painting. In the lower section of the panel, click the
