This mod has the following features:

Disable Shake

When you're in the Aurora, the screen will shake.

Set this option to true to disable shaking.

Disable Bobbing

When moving forward and backward in water, the camera will bob up and down instead of horizontally.

Set this option to true to disable bobbing.

Disable Tilt

When moving left or right in water, the camera will tilt in the direction of movement.

Set this option to true to disable tilt.

Max FOV

Changes the maximum value of the in-game FOV slider.

Actual FOV changes must be set in the in-game settings.

You probably don't want to set the FOV above 160, as this may worsen vertigo.

Disable Mask

When in water, a mask border appears on the edge of the screen.

Set this option to true to disable the mask border, which is equivalent to pressing F6.

Hide Seamoth When Entered

When entering a seamoth, the seamoth model will not be rendered, giving you a wider field of view.

Set this option to true to enable it.

Wave Height

Changes the height of the sea surface waves. When surfacing and looking down at the water, waves can cause disorientation.

The default value is 300.

You can reduce this to reduce the effect.

How to enable them?

Unlike other mods, I don't use SMLHelper or Nautilus, so it has no in-game menu.

com.ex3124.MotionSickness.cfg is the configuration file for this mod, all functions are set in this configuration file.
