Covers the practical patterns for building 3D levels in Godot: GridMap tile placement with proper collision setup, CSG boolean operations for prototyping geometry, and WorldEnvironment configuration for sky and fog. The never-do list is especially useful here, warning you about common mistakes like forgetting to bake navigation meshes, using CSG in production without converting to static meshes, and enabling volumetric fog without directional lights. Includes runtime GridMap builders, coordinate conversion helpers, and a CSG baking tool for converting prototypes to optimized geometry. Best when you're doing modular level design or need to prototype BSP-style architecture quickly before final art passes.
