Why use it
Level designers can test scale, routes, sightlines, and project-specific controls without repeatedly moving through an external modeling package.
Where it fits
Use prototypes and playtests to find core experience problems while they are still cheap to fix.

What to check
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.
