I recently created a new modpack and the player camera isn't moving down at all, so in small spaces I cant see unless I crouch, which isn't ideal for create.

Minecraft version?
Mod version?
Forge or Neoforge?

Minecraft version 1.20.1, Minecraft Forge version 47.2.0, and mod version is 1.4.4

The error still persists when I update my mods, I haven't tried it solo yet to see if its an issue with another mod or not, but none of my mods should mess with the camera.

Version 1.4.4 was built using Forge 47.2.1 due to a Forge change causing a crash, You might need to use 1.4.3 for older Forge versions

I tried downgrading the mod and upgrading forge version, still issue.

I forgot to say it only works when crouching

Not sure why this is happening to you, it works fine for me so guessing it's being caused by another mod

If another mod is messing with the camera there is nothing I can do about it

Should I test all the mods with the shrink mod one at a time to see what mod it is so you could potentially fix it?

If its a mod with an open code you probably could. Tho none of the mods I use add anything to the camera that I know of.

The mod breaking the perspective is Alex's Caves

Fixed, The New build will be on CurseForge in the next few minutes
