Forge 1.18.2

Auto Vanilla / Config

Manual Vanilla / F6

it does this for every item including vanilla ones

also sorry for the late response I was visiting family

I dont know what you mean. Cant tell what this screen contains^^.

Auto vanilla with stick

Works fine for me. Maybe you have an old version or some mod that messes with the player model?

most likely a conflicting mod. Do you know of any conflicting forge mods?

I dont use Forge(or 1.18), but the usual like Epic Fight, I think this version still had issues with Essential, that scale mod the offset is a bit off? But I don't know about mods where it breaks the vanilla hands feature, only that other gun mods have the same issue due to how they add the 3rd person animations.

Most likely not compatible with whatever gun mod that is.
