Lighting & Nav Baker
Overview
A "World Builder" utility that orchestrates the heavy blocking processes of level design. Instead of manually clicking "Bake" on multiple tabs, this skill ensures the environment is fully prepped for gameplay.
When to Use
- •Use after modifying level geometry.
- •Use before making a production build.
- •Use to enforce lighting quality settings (Draft vs Production).
- •Use to rebuild NavMesh Surfaces after moving obstacles.

Best Practices
- •✅ Use
NavMeshSurface(AI Navigation package) instead of the legacy static baker for runtime flexibility. - •✅ Always provide a "Clear" option to remove stale data.
- •✅ Run Lighting Bake asynchronously to avoid freezing the Editor UI completely.
- •❌ NEVER bake lighting in Play Mode.
- •❌ NEVER forget to mark objects as "Static" before baking.
Few-Shot Examples
Example 1: NavMesh Bake
User: "Rebuild NavMesh."
Agent:
csharp
public void BakeNavMesh()
{
var surfaces = Object.FindObjectsOfType<NavMeshSurface>();
foreach(var surface in surfaces) surface.BuildNavMesh();
}
