First Person Model Compat
by Kaokod
First Person Model Compat keeps a player's first-person body stable with combat, spell and roll mods that move the arm, head or accessories.
What it does
The compatibility layer sits on top of First Person Model and synchronizes arm rotation and body offsets with camera pitch while combat animations play. Its phase detection tracks which step of an attack animation is playing, which keeps first-person rendering smoother, and its alignment fixes also cover spell-casting poses, so hands, weapons and staves track the player's view more naturally. During rolls it stabilizes the first-person body so it does not clip with the camera.
The goal is simple: the first-person body stays aligned with the camera, visual clipping is avoided, and obstructive heads or accessories can be hidden in first person while staying visible to other players in third person. The ignoredAccessorySlots option sets which accessory and cosmetic slot names are hidden. Better Combat, Spell Engine, Combat Roll and cosmetic mods are the intended companions here, and EMF-based animation packs like Fresh Animations Player are supported; Entity Player Compat is the suggested addition for resolving clashes with Fresh Moves.
