ControllerFix

Description

Controller Fix is a UE4SS mod for Subnautica 2 that gives you proper control over controller stick behavior through SN2ModSettings.

I was not happy with the default controller feel, so I started digging through the game’s Enhanced Input setup with UE4SS. What I found explained a lot: large built-in stick deadzones, clamped controller sensitivity, and an exponential response curve that makes fine control harder than it needs to be.

This mod removes those limits and exposes the important values in the mod settings menu so you can tune the controls properly.

Major Rewrite

This version is a full rewrite of the original approach. It now patches the underlying input settings more reliably, avoids the old sensitivity restart problem, and keeps the game’s vanilla controller sensitivity menu from silently overriding the modded value.

One of the big discoveries was that controller sensitivity could appear to change, but values above the game’s normal maximum were being clamped or cached unless the game was restarted. This version patches around that behavior, so sensitivity changes apply without needing to restart the game.

Known Issues

-There can be some lag when you close the settings menu because these settings need the full input mapping to be rebuilt in order to be applied.
