Gobos for Lighting | Unreal Engine 5.3.2

In part eleventh of this tutorial series, I will show you how to quickly use gobos with lights to light your scene in UE5.

What is a gobo

A gobo is an object placed inside or in front of a light source to control the shape of the emitted light and its shadow

These were traditionally used for films and theater but have made their way into CGI workflows

Level

Make a new Empty Level

Open the Landscape Mode and add a simple Landscape

In Selection Mode, add a Spot Light and adjust the Intensity as necessary

Also add a Post Process Volume and activate Infinite Extent

Search for Exposure and set the Minimum and Maximum EV both to 1

Gobo

Import the gobo you wish to use in a folder

I will be using a simple gobo I made for a Blender tutorial

Right-click in the folder and make a new Master Material

Open the new Master Material and in the Details panel, change the Material Domain to Light Function

Drag your gobo into the Master Material and connect it to the Emissive Color

Save and close the Master Material

Select the Spot Light and search for the Light Function panel

Drag your new Master Material into the Light Function option

You can now add a Plane and assign a simple material to it

Change the angle of the light and see how the gobo interacts with the Plane
