I agree with Ron- If you apply a MAT Pose and then click the Add to Library button (the "+"), Poser will save the pose back to the library, NOT the MAT Pose. Since MAT Poses are basically "hacks" from cr2 files, there is no way to save a MAT Pose from within Poser. However, you CAN create your own, new, thumbnail (rsr) image: 1) Click the "+" button, but use a different name. 2) Open Windows Explorer, go to the PoserRuntimePoses(subfolder) folder. 3) Delete: the old rsr and the new cr2 files. 4) Next, rename the new rsr to match the old cr2. 5) Re-open the Poses Library and you'll see your new "thumbnail", but since it's the old MAT Pose, it will work just as before. --John
