V44k

V4 4K res. Same pose. Obviously not as pretty as V4's default bends, there's no magnet JCMs here... and that's a problematic bend for V4 at best. Your grouping or joint parms got screwed up somehow in the rig transfer, maybe you got too fancy in your checkboxes?.... Keep it simple. If the files and images aren't sufficient, yeah I don't know. It took like 5 minutes to do this. It took longer changing the geometries file path refs for comparison.
