- Restructured kit_demo.tscn from linear demo to enclosed 5.12x5.12 room with walls, floor tiles, pillar, beam, doorway, window - Added WorldEnvironment with ProceduralSky for ambient lighting - Added DirectionalLight3D (sun key light, 45° angle, shadows enabled) - Added OmniLight3D (warm interior fill light) - Added ReflectionProbe for interior specular reflections (box projection, room-sized extents) - Added LightmapGI with balanced quality settings (bounces=3, texel_scale=1.0, max_texture_size=2048, denoiser=true) - Added tool script (kit_demo.gd) that prints bake status in editor - Added bake_lighting.gd CLI bake script (requires GPU-enabled instance) - Updated project.godot with reflection atlas and shadow map quality settings Headless baking note: Godot's standard editor build requires a GPU/display for LightmapGI.bake(). Open the scene in the Godot editor and click 'Bake Lightmap' on the LightmapGI node to generate the baked lightmap data.
