Learn to build procedural interior spaces in Unreal Engine 5.7 using PCG (Procedural Content Generation) and spline-based shape definition. This intermediate-to-advanced tutorial teaches you to create a reusable Blueprint Actor that automatically generates complete rooms from any drawn spline shape, eliminating hours of manual tile and wall placement.
PCG’s boundary detection techniques using directional point offsets and set difference operations to distinguish interior floor regions from perimeter walls. Build grid-aligned floor tile patterns with configurable spacing, generate properly oriented wall segments along room boundaries, and connect spline modifications to instant room regeneration for rapid design iteration.
The workflow demonstrated applies beyond room generation to terrain features, road networks, vegetation distribution, and any procedural placement scenario requiring edge awareness.
