A specific plugin

[white vault]

Is there a plugin that can either:
A. Auto fix pivot points so mobs don't want around with hovering dislocated legs
or
B. That can play animations for the base mob so I can adjust the pivots accordingly

And while I'm at it, when making OptiFine custom entities, is it easy? Can you customize just about everything? If my current model doesn't work, then I plan on just making it an entirely new entity

You cannot change pivot points as far as I know about optifine.
Besides that, yeah you can do about everything.

Damn that sucks

So I really need to choose a base mob that is close enough to what I want ye?

Changing pivot points requires you to basically counter animate the default animations and merge that with your custom animation on top of it afaik (haven't done it myself before, just some stuff I have heard)

[plain venture]

Oh good Idea, sub bones are allowed right?
So they can have whatever pivots, the default animation just can't run then.

[near bramble]

Yeah, sub bones are allowed

[turbid notch]

you can also use translation animations on the main bones

yeah you can customize about anything, so long as the original groups aren't edited in their pivot points. Subgroups is all you need

though if you want full on customization without 90 million bugs, I highly recommend you make all your subgroups within one folder (body folder to be exact)
