After 2012->2013 upgrade, actors are missing textures

I think what you are seeing is a problem specific to Evolver (now Autodesk Project Pinocchio) content created for FaceFX 2012. Let me know if I'm wrong. The issue is that FaceFX 2012 shipped with the following Material file, but it is absent in FaceFX 2013:

FaceFX Studio Professional 2012\Ogre\Resources\Materials\Scripts\Evolver_FaceFX_Material.MATERIAL

The Doug.Material file references this Material file, but it can't be found. As a result no materials are loaded. In your Logs tab, in the Ogre section, you will probably see warnings like: 'OGRE EXCEPTION(6:FileNotFoundException): Cannot locate resource Evolver_FaceFX_Material.MATERIAL in resource group "

You can fix this by copying the Evolver_FaceFX_Material.MATERIAL file into the equivalent folder in FaceFx 2013. You could also re-export the Ogre files from FaceFX 2013.

For reference, I have pasted the contents of the material file below.
