You can preview Ptex textures assigned to any standard Maya shading network texture input in Viewport 2.0; or, render using the mental ray for Maya renderer.
Note: You can only preview Ptex in Viewport 2.0, mental ray and 3rd party renderers that support Ptex. Using Ptex with the Maya software renderer, the default and high quality viewports is not supported.
To use this feature, the topology of the Ptex file must match the topology of the mesh.
To use Ptex in your Maya scene file

Attention: All attributes on the File node are ignored with the exception of the Image Name attribute.
To render Ptex using mental ray for Maya
- Assign a File node to the surface shader of the object.
- Click the browse button in the File node and select your Ptex file.
- Select the object and create a mentalraySubdivApprox node. You can do this by selecting Window > Rendering Editors > mental ray > Approximation Editor and click Create under the Subdivisions section of the mental ray Approximation Editor.
