I was looking for a way to turn a string value into a Material Instance. I had hoped that Unreal Engine would have a node for that, but alas it does not. Nevertheless, I needed something that like a key/value lookup and came across Map Variables. Those work exactly like a mini-database right inside the …
For character selections, we may want to replace the skeletal mesh of a character according to a user selection. This comes in handy when we want players to be able to select a different character, or the same character wearing a different outfit. Assuming all meshes share the same skeleton, there’s a Blueprint way of …

I was surprised to see how easy it was to setup cloth animations in Unreal Engine. It’s as simple as selecting part of a character we’d like to turn into cloth, painting a weight map onto the wafty parts, optionally adjust settings to make the cloth behave the way we want, and Unreal Engine handles …
Post Process volumes are actually very simple to use. They are essentially invisible box volumes that can apply a camera effect that becomes visible as soon our camera enters them. For this example I’ll show you how to create a very simple underwater yet super popular underwater effect that will turn our image blueish when …

I’ve explained how to make a character crouch in a previous article. We can use the same principle to make him (or her) sprint by setting the Max Walk Speed on our character movement. Let me show you how it works. Just like before we need: a Character (I’m using the First Person Character) an …
Line Tracing is a technique that can tell us if an object is in the line of sight, and returns all kinds of data when true. First person shooter games use it all the time, and the principle comes in handy on so many occasions. While it’s not actually that difficult to comprehend, I find …
I’ve just learnt how to let a player character crouch. It’s a little complicated so I thought I’d take some notes in the intricacies. All credit for this goes to Mathew Wadstein and his excellent video tutorial. I’ll explain how to implement the whole process using an interface call, and I’ll show how we can …
Blueprints can get so disorganised over time: the more nodes we add to our Event Graph, the more cluttered and difficult to navigate the screen can get. While there is a way to search for an event across the current class, and there’s the option to split graphs into Functions, there’s also a way to …
