- 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.
