AgX Tonemapping for Unity

What is this?

AgX is the new color transform introduced in Blender 4.0, surpassing Filmic and ACES in many aspects. This repository contains a collection of AgX LUTs that are compatible with Unity BIRP and HDRP only. (Sorry URP!)

This Unity pack is inspired by the original AgX by Troy Sobotka and the Blender AgX implementation. The LUTs in the pack are configured to provide visual consistency with Blender's OCIO presets:

• Base Contrast
• Medium High Contrast
• High Contrast
• Very High Contrast
• Medium Low Contrast
• Low Contrast
• Very Low Contrast
• Punchy
• Greyscale

Check out the Blender release notes for more information about AgX.

Installation

If you're not familiar with external LUTs in Unity, follow these steps to set it up. Assuming your project is configured in Linear Color Space with a working Post-Process, here's how to add the external LUTs:

1. Download the Unitypackage from from the release page and import it your Unity project.
2. In your global Post-Process Volume Component, add a Color Grading effect by clicking on Add Effect... > Unity > Color Grading.
3. Change the Mode to External.
4. In the Lookup Texture field, drag and drop a LUT of your choice.

Enjoy!
