World Builder is a tool for the Unity game engine that automatically builds out game areas for you. Instead of placing every tree, path, rock, and building by hand, you provide your own 3D models, sort them into categories, then either draw a layout or choose a ready made preset, and click a Generate button. The tool then arranges everything, including full set pieces like boss arenas or treasure rooms, following level design rules meant to make the resulting space fun to explore. It works with any art style, since it does not come with its own artwork, it ships with simple placeholder shapes so you can see how it behaves before swapping in your real models. Getting started takes only a few minutes: open the tool from Unity's menu, generate example placeholder shapes, spawn a ready made layout, and click Generate to see a finished area made of colored blocks. From there, you replace those placeholders with your own models by dragging them into named categories, called slots, inside something called a Biome, which is a simple container that organizes your art by type, such as tall plants, path tiles, or rocks. Layouts can be built three different ways: picking from ready made presets like a straight line to a boss fight, placing marker points in the scene by hand to represent areas like a boss arena or treasure spot, or drawing paths and dropping markers directly onto a top down canvas using a built in drawing tool called the Tracer. All three approaches can be combined in the same project. The tool also supports structure templates, which turn a single marker point into a complete assembled scene, such as a walled boss arena with columns, a gate, and stairs, built from individual pieces you supply. These templates can be adjusted in size and layout without needing to swap out the underlying models. The README is detailed but appears to be cut off before covering every feature, including a section on fences and candles that ends mid sentence, and it does not mention licensing terms.
