Why it’s here
Level designers can test scale, routes, sightlines, and project-specific controls without repeatedly moving through an external modeling package.
Best fit
Prototype systems, stories, and interactions, then validate them with real players.

Before you commit
Boolean modeling is best for blockouts and simple hard surfaces, not a complete final-art pipeline; recheck geometry, UVs, and collision after Godot or add-on upgrades.
