With this project I've tried to recreate the look and sound of real world split-flap displays inside Unreal. It was important to have something that's both really performant and flexible. Using instanced static meshes and material based animation this display has a comperatively small performance impact. As seen in the examples the display can also be reconfigured into many different designs using Unreal's Blueprints.
