No takers so I'll use this thread to babble on as a record for the future.
Plus I forget alot of things and always never keep notes!
I been doing some 'animation' type work for other reasons and learned alot about how Bipeds work and alot of other boreing file structure stuff.
This all klicked in my head a few days ago so I started looking at the SH4 animation areas again.
This is not about props rotation but the animated people stuff.
So don't ask!
A Biped is defined in the SH4 file Secondary.dat
It's listed as Body Parts in S3D. You'll only know what those body parts are if you look at that chunk in Hex.
There's a bunch of them. All with a bip name.
