Let’s look at the amazing effects of LUTs in Unreal Engine - with a free pack included!
Software Required: Unreal Engine 4.24+, Photoshop
Estimated time: 10 minutes
In today's quick tutorial, we'll be looking at one of the most effective post production methods for Unreal Engine. I’ll be using the Snowy Forest scene we made in the previous tutorial for this, but don’t worry, this works for any Unreal project. It’s also completely backwards compatible; I’ll be using UE5.1, but you can follow the exact same steps on any version after UE4.24.
This is a colour lookup table. It informs Unreal what colours to look for and render.
We’ll use one of these to give the scene more mood and atmosphere. A very similar technique known as colour grading is used in filmmaking to convey certain emotions and settings; for my scene, I want to try and amp up the colours slightly, and make the setting look more mysterious and chilly.
So! Let’s start.

LUTs can drastically change the atmosphere of a scene with just a few easy steps. Play around in Photoshop with hue, saturation, black and white values, and the colour select tool. Obviously, this initial example is a bit dramatic - here’s a few of the things you can do:
