Finally got Blender to feel like Studio neo. Had Claude code help build a skeleton based on HS2 armature so you can just import any poses you've downloaded for HS2, same with expressions if you have any presets.
Got FK/IK switcher working but sadly no widget like HS2PE as I'm finding it easier to just have them move via gizmo and also eliminated the annoying FK/IK displacement glitch when switching controls so the pose stay 100% the same when switching from FK to IK and back (so now you can move the shrug bones and have it be kept in IK)
Now the only thing left are the butt, boob jiggle physics and hair physics. Wasted a lot of tokens just trying to get them to work but I just ended up with a buggy mess.
I'm spending a lot more time here than doing my own AVN game but i'll try to juggle both... i hope... So yeah, cool.
