I guess I've been a bit silent about progress on this, huh? well, I finally got the rest of Luigi ripped! as well as a capless head and other hand models! (which I just edited from Mario since they were already pretty similar)

I'm also doing this for Project Ultra 64 Mario Bros! they are working on touching up Kaze's Splitscreen Co-op and adding more features to it!

Interestingly, Luigi's rig was actually a bit asymmetric originally in terms of joint positions, though I touched it up a bit in the arms so they'd be equal length and fixed the weird issue with the hands facing different directions.
