Good luck finding vendors interested in making V4 stuff nowadays. I had been begging for something like the morphing brows for V4 for ages. https://www.renderosity.com/mod/bcs/oh-my-brows-morphing-eyebrows-for-genesis-3-female/115727/ Finally someone figured it was a good idea but naturally vendors will create for figures that are popular. Unfortunately, V4 is now considered obsolete for all but a handful of vendors.
