I am unsure of how it is coded or rendered,
But I have this issue where the first person animations display my vanilla skin instead of my CPM one.

Expectation (McCrayfish's Gun Mod):

Reality (Just Enough Guns):

That should be all, thank you-

The difference is that JEG uses animated guns, which thanks to geckolib, they need a different rendering system

Dang. Fair though...
So it'd be more of a geckolib issue?
