Earlier this year I came across an excellent blog post by Parallelcube that went over a way of how to add parallax scrolling to a material. It's a great blog post, check it out if you get a minute. And then the other day I wanted to practice some C++ inside Unreal so I looked at this example and wondered if I could have some fun programming a small portion of this feature. There's a Blueprint function where we set the parameter values on Tick and I wondered if I could somehow make it programmatically. The solution wasn't immediately apparent, I had to try a few things and look at couple different resources, but I eventually landed on a solution.

Check out the blog post by Parallelcube for a full breakdown of the parallax scrolling material, but essentially we connect all the relevant textures inside a material and then add an offset value to each layer on every tick. Decided to go with a pretty cool and spooky parallax forest background by Digital Moons for this example. I first started by importing the textures into Unreal.
