How to Dissolve a Mesh Using Signed Distance Fields in Unreal Engine 5

In this video, I will show you how to dissolve a mesh using any static mesh or a box mask. This is an upgrade to my older tutorial, but this one I have added the ability to rotate the box mask and also use any mesh using Signed Distance Fields in Unreal Engine 5 Material.

What you will need:

Unreal Engine 5
A static mesh or a box mask
A material that uses Signed Distance Fields
Steps:

Import your static mesh or box mask into Unreal Engine 5.
Create a new material and add a Signed Distance Field node.
Set the mesh or box mask as the input for the Signed Distance Field node.
Set the dissolve threshold as desired.
Apply the material to your mesh or box mask.
Result:

Your mesh or box mask will dissolve according to the dissolve threshold you set. You can also rotate the box mask by adjusting the rotation values in the material.

Tips:

You can use any mesh or box mask for this effect.
You can adjust the dissolve threshold to control how much the mesh or box mask dissolves.
You can rotate the box mask to control the direction of the dissolve.
I hope this tutorial was helpful. Please let me know if you have any questions.
