Unreal Engine Blueprints Building Generator (UE) v5.0

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 which can be used to quickly generate buildings. It only requires meshes and then the spline-based algorithm will take care of the rest. Because it is based on splines you have full control over the primary shape of the building. The blueprint is also capable of generating several buildings at once which are based on a grid making it possible to create entire blocks or cities quickly. There is no support for interiors at this point in time.

The buildings are generated from the ground up during each cycle based on the properties given. The generation method is deterministic (seed based) meaning that the exact generation can be regenerated given the same seed and properties. Building length, width and height can be determined prior to generation whilst adding random values. Likewise, the properties of each building can be altered. These properties include, but are not limited to, roof, cornice, curb, gutter, entrances, signs etc. Both Lumen and Nanite are compatible, and collision can either be simple or complex. Generation during runtime is possible. The buildings are game ready in terms of draw calls as they are utilizing Unreal's HISM (Hierarchical Instanced Static Mesh) which also support LODs. The roofs, curbs, sidewalks and cornices are all generated using procedural meshes. Version: 5.0
