My goal is just maintaining the mod.

BetterSpectate

Improves the versatility of the spectator camera.

This client-side mod aims to provide highly customizable improvements to the spectator camera.

Features

First Person

Config

Both the zoom and first person spectate features can be disabled in the config file located in BepInEx/config/Fusition.BetterSpectate.cfg

• Zoom Speed changes how quickly the camera will zoom in. Note: If this is too high, zooming in or out will appear jumpy.
• Max Zoom Distance configures the furthest point from the player that you can zoom out to.
• Min Zoom Distance configures the closest point to the player that you can zoom in to.
• Default Zoom Distance determines how far from the player the camera will start upon death or switching to third person view from first person.
• Default to First Person controls the perspective that you will start in upon death.
