wish Geodav hadn’t fallen asleep could use that version myself, thought i’d try out the nightly build as well, looked really hopeful but the one I downloaded someone’s messed it up as well. just like yours TheBricktop
after the shoulders or the Clavicle the bones are crunched up against the body,(neck down was fine) and won’t work unless I retarget them someway. (TheBricktop if you notice the show tab in that view you posted click it n check bones and you’ll see why that looks that way)
anyway, save that version Geodav & upload it for us if you have somewhere you can. it seemed to work from watching your video.
