EasyLUT Plugin Documentation

What is EasyLUT?

EasyLUT is a plugin for Unreal Engine that simplifies the process of importing and applying LUT (Color Lookup Table) files. It supports popular LUT file types, automatically converting them into Unreal-compatible textures and materials for use in post-process effects.

Key Features:

Drag-and-drop import of LUT files.
Automatic creation of LUT textures and material instances.
Seamless integration with Unreal Engine's Post Process Volume.

Supported File Formats

'.cube'
'.lut'
''.3dl'

Installation

Install the Plugin
- install it via the Unreal Engine Plugin Manager.
- Alternatively, copy the plugin folder into your Unreal project’s 'Plugins' directory.
Enable the Plugin
- Go to Edit > Plugins in Unreal Engine.
- Search for "EasyLUT" and enable it.
- Restart the editor if prompted.

How to Use EasyLUT

1. Importing LUT Files

Drag and drop a .cube, .lut, or .3dl file directly into the Unreal Engine Content Browser.
Upon import, the plugin will:
- Create a volume texture from the LUT file.
- Generate a material instance based on the included post-process material.

2. Applying the LUT

Add a Post Process Volume to your scene (if one doesn’t exist already).
Open the Post Process Volume’s details panel and:
- Set the Volume Type to Infinite (if you want the LUT to apply globally).
Assign the generated LUT material instance to the Blendables section of the Post Process Volume.

Customization

Material Parameters:

Use the "BlendStrength" parameter in the material instance to control the intensity of the color effect. You can control this parameter from the Sequencer by using the included Material Parameter Collection (MPC).

Troubleshooting

LUT File Not Importing:

Ensure the file is in one of the supported formats ('.cube', '.lut', '.3dl').
Check that the plugin is enabled in the Plugins menu.

Post Process Material Not Working:

Verify that the Post Process Volume has the correct material instance assigned in the Blendables section.
