Procedurally generate a single building or a city with a click of a button. Control the shape of the building using a simple spline system, then add meshes and let the algorithm handle the rest. Building Generator is a blueprint-based building generator that can quickly generate buildings using only meshes. The spline-based algorithm takes care of the rest, giving you full control over the primary shape of the building. The blueprint can also generate multiple buildings at once based on a grid, enabling fast creation of entire blocks or cities. Currently, interior generation is not supported.
Buildings are generated from the ground up in each cycle based on defined properties. The generation method is deterministic (seed-based), so the same result can be reproduced with the same seed and properties. Building length, width, and height can be set before generation, with optional random values. Properties such as roof, cornice, curb, gutter, entrances, and signs can be customized. The tool is compatible with both Lumen and Nanite, and collision can be set to either simple or complex. Real-time generation is supported. The generated buildings are game-ready in terms of draw calls, utilizing Unreal's HISM (Hierarchical Instanced Static Mesh) system, which also supports LODs. Roofs, curbs, sidewalks, and cornices are created using procedural meshes.
