Previewing Ptex textures

You can preview Ptex textures assigned to any standard Maya shading network texture input in Viewport 2.0.

ImportantYou can only preview Ptex in Viewport 2.0 and 3rd party renderers that support Ptex. Using Ptex with the Maya software renderer and the mental ray renderer, and the default and high quality viewports are 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

Select Renderer > Viewport 2.0 to switch to Viewport 2.0.
Select Renderer > Viewport 2.0 > . Your Ptex information will be baked into a 2D Texture. Set the Color Textures attribute under Bake Resolution for Unsupported Textures to the resolution you desire.
Assign a File node to the surface shader of the object.
Click the browse button in the File node and select your Ptex file.

NoteTo display your Ptex textures in high quality, you should increase the Color Textures resolution to, for example, 2048. After adjusting the Color Textures resolution, you must click Re-bake All Textures to see the effect of the change.

ImportantAll attributes on the File node are ignored with the exception of the Image Name attribute.
