Full procedural generation is available in the PRO version.This tool is not intended for drawing buildings or generating levels at runtime.Living Update:Any changes you make to prefabs, rooms, or settings trigger a live update of the entire building. This process is extremely fast—updating a building with 5000 cells takes approximately 30-40 ms.It also supports multiple buildings in the scene. This allows you to create large levels with unlimited buildings.Rule-based spawn:Prefab setup is rule-based and does not require programming. The interaction between the build system and prefab rules is tag-based. Rules are unificcated and simple to understanding.
