Karen, I'm working hard on this issue right now. It's also a problem with MPE: the MAT files should contain the nodes so that P5 would apply the MATs properly. Testing has been difficult for me because I don't have P5 but I've still managed to get 100% working results with the in-progress MPE beta which creates the needed node data in the pose files. You'll be able to test it very soon. It would help me if you e-mailed the MAT file to me. I can then make the needed adjustments and additions to it and send the fixed file to you for testing with P5. Thanks, Ilari
