Use cases

Built for real projects

Sims-style construction games

Place walls, floors, and rooms at runtime. Players build freely with live preview, corner joining, and room fill — exactly the mechanics behind life-simulation construction modes.

Architectural visualization

Prototype floor plans interactively. The polygon-based floor system and wall placement tools work in-editor and at runtime — ideal for archviz and spatial planning tools.

Runtime level editing

Let players modify their environment at runtime. Save and load wall and floor state between sessions with the built-in save managers. Fully Blueprint-accessible.
