As amazing as Ptex is, and sounds, sporadic and partial implementation of Ptex kind of make it a bit challenging to work with. Setting out to devise a workflow and seek out the pro’s and con’s of using Ptex in a project, Therenderblog posts an article defining the workflow between Maya using Arnold and Mari using Ptex instead of UV tiles.

Here, João walks through how he painted Ptex textures in Mari and the Workflow for using Maya and Mari together while providing some great tips for photoshop and Mari. Check out the tutorial for Ptex workflow with arnold and mari over at Therenderblog here.
