Hi Guys,
Since AD hasn’t integrated this process, I thought I would give you all a heads up on how to use PTex textures in Maya 2013:
Set PTex registry value for mental ray for Maya:
Create/edit file maya.rayrc in the user Maya directory 2013/prefs/ (or 2013-x64/prefs/ or /Maya2013/mentalray/) and add the new registry setting below.
[b]Example (Maya2013 64bit on Windows Vista/7):[/b]
Edit the file:
C:\Program Files\Autodesk\Maya2013-x64\prefs\maya.rayrc
add the following line:
registry "{_MI_REG_CCMESH_PTEX}" value "on" end registry
