Tired of ACES crushing your colors?

UE5's default ACES tonemapper shifts hues in bright saturated lights (reds turn orange, blues turn purple). AgX fixes

this. It's the same tonemapping algorithm Blender adopted as its default, now adapted for Unreal Engine 5 as a drop-in

Post-Process Material replacement.

What You Get

• Post-Process Material (M_AgXToneMapper) with Custom HLSL implementing the full AgX pipeline

• Material Instance (MI_AgXToneMapper) ready to drop into any Post Process Volume

• Complete HLSL source code with detailed inline documentation

Features

• Accurate hue preservation, saturated colors stay true under bright lighting

• Smooth highlight rolloff to white without clipping or hue shifts

• Auto-exposure support via Eye Adaptation
  

Plug-and-Play:

setup steps:

1. Drop the MI_AgXToneMapper into a post proccessing volume

2. Enable Infinite Extent

3. Done

Important Note :

This is a Post-Process Material, it applies to the scene viewport and gameplay camera. The Material Editor preview

and Content Browser asset thumbnails use their own rendering pipeline and will not show AgX tonemapping. Assets will

display with AgX only when viewed in a level with the Post Process Volume active.
