weight: -7.0 to 7.0
positive: zoom in (face close up)
negative: zoom out (full body)
This is NOT perfect. I have tried to make this for a very long time using a dozen different methods and nothing worked. My slider training script was finally able to kick something out that is decently functional. I will continue to work on it because this is the slider I want more than anything else.
The slide in and out is not always smooth, it will hit points that "hang" where the clothing mostly changes for 1-3 weight steps without changing zoom, but it will break through if you keep pushing it. Let me know if you find any thing that can use improvement.
