// Scene lighting, light object properties, fog, background, tone mapping, and post-processing for Studio 3D. Use for mood, atmosphere, shadows, and visual environment setup.
Asset search (local and external), asset metadata lookup, model import, and 3D model generation for Studio 3D. Use for finding, inspecting, downloading, and placing 3D models in the scene.
Add sound effects and audio to 3D scenes in Studio 3D game engine. Use when the user asks to add sounds, music, audio feedback, or sound effects to objects or events. Covers the genericSound behavior for event-triggered audio, audio resource management, and common patterns like ambient sound, collision SFX, UI click sounds, and background music. Examples include "add a sound when the coin is collected", "play background music", "add footstep sounds to the character", or "make the button click sound".
Behavior discovery, creation, update, attach/detach, and configuration in Studio 3D. Use for built-in behavior reuse first, then custom behavior authoring only when needed.
Camera type, perspective, and configuration for Studio 3D. Use for camera type selection, FOV, clipping planes, and genre-appropriate camera setup.
Master routing skill for StemStudio ACP work. Use for broad or ambiguous requests such as "make a game", "build a scene", "improve this", or any task that needs skill selection, scene inspection, staged execution, and clean scene hierarchy.
EventBus guidance for behavior-to-behavior messaging in Studio 3D. Use when behaviors need decoupled communication, topic design, or event lifecycle cleanup.

Use this skill for scene-wide lighting, fog, background, tone mapping, and post-processing.
Read current settings before making broad changes:
python scripts/get_editor_settings.py --category lighting
python scripts/get_editor_settings.py --category fog
python scripts/get_editor_settings.py --category background
python scripts/get_editor_settings.py --category postProcessing
python scripts/set_scene_lighting.py --ambient '{"color":"#fffaf0","intensity":0.6}' --hemisphere '{"skyColor":"#87CEEB","groundColor":"#4a7c59","intensity":0.4}' --shadows '{"enabled":true,"mapType":"PCFSoftShadowMap"}'
python scripts/set_light_properties.py --target "Directional" --intensity 2 --color "#ffffcc" --castShadow true --shadowMapSize 2048
Use set_scene_lighting.py for scene-wide ambient/hemisphere/shadow defaults. Use set_light_properties.py for a specific light object.

python scripts/set_tone_mapping.py --type ACESFilmic --exposure 1.1
python scripts/set_tone_mapping.py --type Reinhard --exposure 0.9
Types: None, Linear, Reinhard, Cineon, ACESFilmic.
python scripts/set_post_processing.py --bloom '{"enabled":true,"strength":0.8,"radius":0.3,"threshold":0.7}'
python scripts/set_post_processing.py --ao '{"enabled":true}' --bloom '{"enabled":true,"strength":0.5}'
Effects: ao (ambient occlusion), bloom, outline.
When the user asks for a mood like "night", "sunset", or "horror":
Do not treat this as purely a lighting task if the request is about scene feel.
