How to Create an Object Material with a PSD Network in Maya
A PSD Network is a single Photoshop file that contains the various texture nodes (i.e., Color, Transparency, Bump, etc.) as separate Photoshop layers. The original PSD file is created in Maya, then you open the file in Photoshop and start the painting process.
Open a new Maya document and start a new project. Be sure to set your project and save your new scene. For more information, see topic, Starting a Project.
Add a polygon Cube to the workspace by choosing Create > Polygon Primitives > Cube.
Select the cube, then right-click the cube and choose Assign New Material > Blinn.
With the cube selected, choose Texturing > Create PSD Network from the Rendering menu set.
In the dialog box, Image Settings section, Image Name box, you can see the default name given to your PSD file. It will be saved in your project's sourceimages folder.
Click the Open in Adobe (R) Photoshop (R) checkbox if you want the file to automatically open in Photoshop.
Size X and Size Y specify the Photoshop document size.
In the UV Settings section, enable the Include UV Snapshot checkbox. This will create a separate layer with a UV map snapshot that can be used as a template.
In the Attributes Selection section, Attributes box, click Color, then Cmd-click (PC - Ctrl-click) Transparency, then Bump. All three should be selected. Click the right facing arrow to move the attributes to the Selected Attributes box.
Click the Create button to launch Photoshop and open your new PSD file. If the file doesn't open as expected, go to your project's sourceimages folder and find the image. Check to make sure the file path is correct in the Maya Preferences > Applications category, The Application Path for Editing Adobe Photoshop Files should point to the Photoshop application.
In Photoshop, the top layer is the UV Map template. Inside of each of the folders is a map for Color, Transparency and Bump. This is the exact same layer structure you need when you are finished editing the PSD file.
Edit the Color, Transparency and Bump layers using the UV Map layer as your guide. You will need to turn off the upper layers' visibility to work on the lower layers. Once you are finished, save your document.
Return to Maya add lights to your scene and and click the Render Current Frame icon.
Editing Your PSD Network
To edit your texture, open the PSD image in the sourceimages folder. If you want to add another attribute to the PSD network, select the object, then choose Texturing > Edit PSD Network from the Rendering menu set.
Transparency Layer - White is Transparent
As you create your Transparency layer, remember that white areas are transparent and black sections are opaque.
Adjusting the Bump
If you find the bump map needs adjusting, open the Attribute Editor, bump2d tab and increase or decrease the Bump Depth value.
