StemStudio Atmosphere
Use this skill for scene-wide lighting, fog, background, tone mapping, and post-processing.
Start Here
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
Critical Workflows
Lighting
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.
Fog
python scripts/set_scene_fog.py --type linear --color "#c8d8c0" --near 5 --far 50
python scripts/set_scene_fog.py --type exponential --color "#1a1a2e" --density 0.05
python scripts/set_scene_fog.py --type none
Background
python scripts/set_scene_background.py --type Color --color "#0f172a"
python scripts/set_scene_background.py --type Gradient --gradient '{"topColor":"#87CEEB","bottomColor":"#f0e68c"}'
Tone mapping
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.
Post-processing
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.
Atmosphere routing
When the user asks for a mood like "night", "sunset", or "horror":
- inspect current settings first
- change lighting, fog, background, tone mapping, and post-processing together
- verify after each major change set
Do not treat this as purely a lighting task if the request is about scene feel.
Routing Guidance
Use this skill for:
- lighting and shadow configuration
- specific light object intensity, color, castShadow, and shadow map properties
- fog type, color, and density
- background color, gradient, or cubemap
- tone mapping type and exposure
- post-processing effects (bloom, AO, outline)
Do not use this skill for:
- camera configuration (
stemstudio-camera)
- game rules or rendering quality (
stemstudio-project-settings)
- VFX/particle effects (
stemstudio-vfx)
- object materials (
stemstudio-materials)
Verification
After atmosphere changes:
python scripts/get_editor_settings.py --category lighting
python scripts/get_editor_settings.py --category postProcessing
Common Mistakes
- changing many categories without first reading current settings
- adjusting only one setting when the user really wants a full atmosphere change
- overusing post-processing before fixing lighting and fog
- not coordinating lighting, fog, and background together for mood changes
When To Read More
- Need category defaults or setting interactions:
~/.claude/stemstudio-docs/editor-settings.md
- Need exact command parameters:
~/.claude/stemstudio-docs/commands-reference.md
