This is not the final version, so there may be bugs for now.
The settings can be changed in the file SKSEPluginsSKSE_EnhancedCamera.ini by the address Data \ SKSE \ Plugins.
Both the body itself and many actions in which the camera previously switched to a third-person view will be visible (riding a horse, being in the form of a werewolf / vampire lord, flying on a dragon, death, crafting, and so on).
This is a kind of hybrid, which uses the hands from the first person and the body from the third.
This SKSE plugin, extending the possibilities of the first-person view.
