I think you are misunderstanding the JCM part. Millie is the remapped version of Victoria. The PCF encoded version is about 2 meg zipped. But it is the full deal. The UVS encoded version is about 0.7 meg zipped, However - as I found out after I did it, UVS does not allow for new materials and Millie has a new material. The V2P4 version does not, it is not the version to use if the new material is involved anyway. The JCM is Joint controlled morphs. Point the toe and the calf flexes, bend the forearm and the biceps flex, lift the arm and the breast rises,etc. The joint works the morph. This sort of morph would not be very rewarding to do with the P4 figures, because the mesh density is too low to allow for much detail.
