Disabling Post Effects on Unreal Engine
=======================================

Introduction
------------

This guide provides instructions on how to delete or disable post effects on Unreal Engine 4 and Unreal Engine 5 games. The steps outlined in this guide can help improve performance and reduce visual issues.

Unreal Engine 4
---------------

The following post effects can be disabled in Unreal Engine 4 games:

- Motion Blur
- Depth of Field
- Chromatic Aberration

Phase 1: Editing the Engine.ini File
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To disable these effects, follow these steps:

#. **Locate the Engine.ini File:** Head over to :file:`%APPDATA%` or :file:`%LOCALAPPDATA%` and navigate to the game's configuration directory:

   - **Steam:** :file:`"GAME"/Saved/Config/WindowsNoEditor`
   - **Windows Game Store:** :file:`"GAME"/Saved/Config/WinGDK`

#. **Edit the Engine.ini File:** Open the :file:`Engine.ini` file and add the following lines at the bottom:

   .. code-block:: ini

      [SystemSettings]
      r.DepthOfFieldQuality=0
      r.MotionBlur.Max=0
      r.MotionBlurQuality=0
      r.DefaultFeature.MotionBlur=0
      r.SceneColorFringe.Max=0
      r.SceneColorFringeQuality=0

#. **Save and Set to Read-Only:** Save the file and set it to `Read Only` to prevent accidental changes.

.. admonition:: Notes
   :class: note

   - Keep in mind that changing settings in-game may require a restart to apply the changes made to the :file:`Engine.ini` file.
   - This method may not work in every instance, and results may vary.
   - For more information on modding the :file:`Engine.ini` file, visit the `PC Gaming Wiki <https://www.pcgamingwiki.com/>`_.

Unreal Engine 5
---------------

Unreal Engine 5 games require different settings to disable post effects. The following example is for HellBlade 2:

.. code-block:: ini

   [SystemSettings]
   r.SceneColorFringeQuality=0
   r.Tonemapper.GrainQuantization=0
   r.Tonemapper.Quality=0
   r.NT.Lens.Distortion.Intensity=0
   r.NT.Lens.Distortion.Stretch=0
   r.NT.Lens.ChromaticAberration.Intensity=0
   r.NT.DOF.RotationalBokeh=0
   r.NT.DOF.NTBokehTransform=0
   r.FilmGrain=0

To remove letterboxing, add the following lines:

.. code-block:: ini

   r.NT.AllowAspectRatioHorizontalExtension=0
   r.NT.EnableConstrainAspectRatio=0

.. note::

   Unreal 5 games will be a **case-by-case basis** until we release an addon to disable specific effects.

Shader Toggler
--------------

The Shader Toggler is a free ReShade add-on that can disable certain effects that may cause issues with Depth3D. You can learn more about it in our `ReShade guide <../reshade/reshadeversions>`_.
