How to Paint a 3D Object in Photoshop
Painting and adding color to a 3D object in Photoshop is quite easy. Whenever you create a 3D object, one or more diffuse maps are automatically added to the Layers panel. To access the map, simply click the Brush tool (b key)and start painting.
In this example we will add a soda can from the Mesh Presets and begin the painting process.
In Photoshop open a new blank document (File > New). Set the image size to 1,024 pixels by 1,024 pixels. Save the document as SodaCan.psd.
In the Layers panel, click the Create a New Layer icon.
Choose 3D > New Mesh from Layer > Mesh Preset > Soda to add a soda can to the layer.
With the Rotate 3D Object icon selected, click and drag in the View box to move the camera so you can see both the top and front of the can.
Click Soda in the 3D panel, then select the Brush tool (b key), set a new foreground color and start painting the front of the can.
Paint a design on the top of the can.
Depending on where you paint, the color is applied to one of two diffuse maps. To see the label diffuse map, double-click the Label Material - Default Texture layer in the Layers panel.
The map is the same size as your document (1,024 x 1,024) and can be painted and edited as a normal Photoshop document. Also note that when you opened the diffuse map, it is identified as a .psb file in the image tab.
Once you are finished editing the map, you can return to the main document by clicking the SodaCan.psd tab. Your changes are automatically saved.
