I hope you don't mind me putting this here, but as you're the only person I've seen posting this asset I thought I'd help folks out:

For people who are confused why their booty jiggles weird and the physbone looks off, but don't understand why:

Physbone on Butt_Root.L has its X Endpoint Position set to "0.01" instead of "-0.01". EZ fix

@PurpleElysia this should be the latest version! Bought just yesterday, and it hasn't been updated since about 2 weeks ago.

I sadly do not have the Gamma/ full set.

If another version comes out for Alpha, do feel free to ping me.
If I end up getting the other set as well, I'll post it here
