Injection morphs are handled by P4 just like P5. It's a cool trick that rbtwhz figured out. The morph information is actually in another directory and the morph injection files load that information when you click on the injection files. This allows you to load only the morphs you want. It can take a few minutes if you load every freaking V3 morph. If you have a few morphs that you use all the time, you can always load those morphs into the V3 figure and then save that as a .cr2 file for convenience. V3 to V2 can use V3 head morphs. V2 head morphs are not compatible with V3. Different meshes. I haven't tried V2 body morphs on V3 to V2, but I doubt it would work. Hope this helps!
