Thanks to the help from the "Poser Professors" (many thanks again) I'm starting to get my Pose library reduced, (I had 215 files). I'm consoladating the pose files, and changing the file names to list them in a more logical listing. My question now is about the "MAT" files. Can I rename the "MAT" files in the library? I'd like to to put the word "MAT" as the first word of the MAT file. Example: Vicky Beach Tan MAT MAT Vicky Beach Tan or Example: Bertha MAT Bertha Can I make these changes without harming any thing. Do I need to use any additional programs? I have CorrectReference, and P3Do 1.6(just downloaded them), but I don't know how to use them. PBooost 1.4 is suppose to be out soon, and I intend to get it when it does.
