You can use any Photoshop painting tools to paint direct on a 3D model just equally you would on a 2D layer. Use choice tools to target specific model areas or allow Photoshop identify and highlight paintable areas. 3D menu commands permit you clear away areas of a model to access interior or subconscious portions for painting.

When painting directly on the model, you can choose which underlying texture map to apply paint to. Typically pigment is applied to the diffuse texture map, which gives a model material its color properties. Yous tin can also paint on other texture maps, such equally the bump map or opacity map. If y'all pigment on an expanse of the model that lacks the blazon of texture map y'all're painting on, a texture map is automatically created.

Bachelor 3D painting methods

Different painting methods are appropriate for different utilise cases. Photoshop provides the following 3D painting methods:

Live 3D Painting: (Default in Photoshop) Brush strokes made in the 3D model view or the texture view are reflected in existent time in the other view. This 3D painting method offers high functioning and minimum distortion.

Layer Projection Painting: The Gradient tool and filters use this painting method. The Layer Projection Painting method involves merging a painted layer with the underlying 3D layer. During the merge performance, Photoshop automatically projects the paint onto the appropriate target textures.

Projection Painting: (Default in Photoshop Extended CS6) Projection Painting is suitable for painting multiple textures simultaneously or for painting the seam between ii textures. All the same, in full general, it is a lower-functioning painting method and may result in cracks when you're painting complex 3D objects.

Texture Painting: You can open the 2D texture and paint it directly.

Live 3D Painting

Some tips to paint 3D models

• If the model surface area is subconscious, you can temporarily cut away surface areas that are blocking your view. See Reveal surfaces to pigment on.
• If yous are painting on curved or irregular surfaces, you tin get visual feedback earlier you paint of which areas can best receive paint. See Identify paintable areas. You tin also set the paint fall-off angle, which controls the amount of pigment practical to angled surfaces. Run across Set the pigment falloff angle.
• While painting texture seams, a single castor postage stamp applies only to one side of the seam. Move the eye of the castor across the seam to pigment its other side.

• If you attempt to paint on a texture map type that the material doesn't comprise, Photoshop prompts you to create a map. For information on map types, see 3D Materials settings (Photoshop Extended).

Paint an object in the Alive 3D Painting style

1. Open up the 3D model in the 3D model view.
2. Open the texture document that yous want to paint. To practice so, double-click the proper name of the texture in the Layers panel.
3. Select Window > Accommodate > Tile to view the 3D model view and the texture document adjacent.
4. Using the Brush tool, paint the 3D model or the texture document. Your brush stokes reverberate automatically in the other view.
   

Switch to the Projection Painting style

1. Create or open a 3D model.
2. Select 3D > Use Projection Painting.
3. Pigment your 3D model.
   

In the Main 3D certificate, Photoshop uses the Projection Painting method by default for painting operations.

Unwrap UVs of a 3D model

Photoshop provides an option to automatically unwrap UV maps for your 3D model.

1. Open the 3D model.
2. Select 3D > Generate UVs.
3. The warning When using Generate UVs, all of the meshes' materials' textures will exist flattened is displayed. Click OK to continue.
4. In the Generate UVs dialog box that appears, choose the following textile and unwrapping options:
   

Merge Materials

If multiple maps—for example, Diffuse and Crash-land maps—exist on a single mesh, combine them into one map.

Case: Combine ii different Diffuse maps into 1 Diffuse map.

If you accept multiple meshes, each of them will however have their own map. For case, if you have three separate meshes with iii Lengthened maps, you'll still accept 3 separate Diffuse maps for each mesh.

Preserve Appearance

On a best-endeavour basis, maintains the look of the 3D model and its textures when new UVs are generated. If you cull to not enable this selection, the electric current textures are not preserved.

UV Map Size

Select the required size for the generated UV maps (pixels x pixels). You have the option choose 128, 256, 512, 1024, 2048, or 4096.

Low Distortion

Keeps the texture blueprint more intact, but tin can create more seams on the model surface.

Fewer Seams

Minimizes the number of seams that appear on the model. This can produce more stretching or pinching of the texture, depending on the model.

5. Click OK.
6. You lot tin can view the generated UVs under the Diffuse section in the Layers panel.

After generating UVs for a Fuse model, the model moves from its original position. This is a expected behavior in most rigged models, as the rigged position is dissimilar from the position of the mesh. The model shifts to the mesh position because the rig is removed when generating UVs for that model.

To preview any of the generated UV maps, hold the cursor over the layer particular in the Layers panel. To open up the UV map in a separate window, doube-click that layer item.

Target a texture type for painting

You tin target eight unlike texture types for painting:

1. With your 3D model open, select 3D > Paint On Target Texture.
2. Choose the texture type that you want to paint.
   

In 3D models having multiple textures, but the texture that you open and start painting on is painted.

Paint a target texture type

Paint in the unlit mode

You lot can choose to pigment your 3D objects in the unlit mode. This manner ignores any lighting in your scene and wraps raw texture information of the appropriate blazon around your 3D objects. Painting in the unlit mode lets you paint without shading and with greater colour accurateness.

Follow these steps:

1. In the 3D panel, select Scene.
2. In the Properties panel, select Surface.
3. Select Unlit Texture from the Style pop-upward carte du jour.

Reveal surfaces to pigment on

For more complex models with interior or hidden areas, you lot tin can hibernate sections of the model for easier access to surfaces y'all want to paint. For example, to utilise paint to the dashboard of a auto model, you can temporarily cutting away the roof or windshield, then zoom within the machine to become an unobstructed view.

Select an expanse of the model that you want to cutting away, using a option tool such as the Lasso or Marquee tool.

Utilise any of the following 3D carte commands to reveal or hide areas of the model:

Hide Nearest Surface

hides only the commencement layer of model polygons within the 2D selection. To quickly peel away surface of the model, you lot can use this command repeatedly while keeping the choice area active.

When hiding surfaces, rotate the model if necessary to position surfaces so that they are perpendicular to your currentview.

Only Hide Enclosed Polygons

When selected, the Hide Nearest Surface command but affects polygons that are fully inside the selection. When unchecked, ithides 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 once 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 forrard-facing view. The falloff bending is calculated based on a "normal", or straight line projecting out from the part of the model surface that faces you. For case, in a spherical model such as a soccer ball, the falloff bending to the exact center of the ball as it faces y'all is 0 degrees. Equally the surface of the ball curves away, the falloff angle increases, up to 90 degrees at the edges of the ball.

A. Eye/camera angleB. Minimum angleC. Maximum angleD. Paint fade get-goE. Paint fade stop

Cull 3D > 3D Pigment Falloff.

Set the minimum and maximum angle settings.

• The maximum paint falloff range is 0 - ninety degrees. At 0 degrees, pigment is only applied to the surface if information technology is facing directly forward, with no drop-off angle. At 90 degrees, paint tin can follow a curved surface such as a sphere to its visible edges. At a 45 caste setting, the painted expanse is express to the areas of the sphere that don't bend abroad at more than 45 degrees.

• The Minimum falloff angle sets a range within which paint gradually fades as information technology approaches the maximum falloff bending. For case, if the maximum falloff bending is 45, and the minimum falloff is 30, paint opacity decreases from 100 to 0 percent betwixt 30 and 45 degrees of falloff.

Identify paintable areas

It may not exist articulate just from looking at a 3D model whether yous can successfully paint on certain areas. Because the model view may not provide a 1 to 1 correspondence with the 2nd texture itself, applying pigment direct to the model is unlike from directly painting on a 2d texture map. What appears to exist a small-scale brush on the model may in fact be much larger in relation to the texture, depending on the resolution of the texture, or how close y'all are to the model when applying paint.

Good paintable areas are areas where you can apply pigment or other adjustments to the model surface with the most consistent and predictable effect. In other areas, paint may be undersampled or oversampled due to your angle or distance from the model surface.

• Choose 3D > Select Paintable Areas. A selection marquee highlights the best areas for painting on the model.

• In Scene section of the 3D panel, choose Paint Mask from the Preset menu.

  In Paint Mask mode, white shows areas skillful for painting, blue shows areas where pigment volition be undersampled, and red shows areas where pigment will be oversampled. (To paint on the model, you must change from the Pigment Mask render mode to a return way that supports painting, such every bit Solid.)

The areas selected past Select Paintable Areas, and the paintable areas shown in Paint Mask style, are partially adamant by the current Paint Falloff setting. A higher paint falloff setting increases the paintable area, a lower setting decreases the paintable area. Run into Gear up the paint falloff angle.
