Hi there 😊
Welcome to Voxüels; the super fast, efficient, easy-to-use voxel engine that's built to work with Unreal Engine's best features, not replace them!
Before trying to open or build the project, install the Fast Noise Generator plugin to the engine.
Once the plugin is installed you can open the project like any other; have fun messing around!
NOTE A "Starter Content" directory may be added to the project when you first open it. I accidentally left the "Starter Content" toggle checked when I first created the project. I'm looking to see if there's a setting somewhere I can update that stops this from happening. The directory won't hurt anything; it's just unnecessary clutter.
