What it does
3D Four Seasons is an agent skill from MengTo/Skills. Add coordinated spring, summer, fall, and winter states to a 3D scene, blending foliage, sunlight, sky, ground materials, snow, and particles without rebuilding the world. Use for seasonal controls, architectural walkthroughs, and outdoor scenes with four-season transitions.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `REFERENCES.md` and `agents/openai.yaml`).
It sits in Game Development, covering 3D graphics and WebGL. The repository describes itself as: Agent skills for designers and builders using Codex, Claude, Cursor, and other AI coding agents. The licence is MIT.
When your agent uses it
- Seasonal controls
- Architectural walkthroughs
- Outdoor scenes with four-season transitions
Example prompts
- “/3d-four-seasons”
What it can do on your machine
Read from SKILL.md and the folder at commit 83a47fe. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
3D Four Seasons loads about 1.3k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 558 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

3D Four Seasons
Keep one recognizable place across all four seasons. Each season should change several mutually consistent visual cues while preserving camera state and interactions.
Author the seasonal identity
Inventory deciduous trees, evergreens, exposed surfaces, sheltered surfaces, lights, sky, and existing weather. Use species and climate appropriate to the project; the table is a temperate-scene starting point.
| Season | Foliage and ground | Light and atmosphere | Motion |
|---|---|---|---|
| Spring | Fresh foliage; blossom on appropriate species | Soft warm daylight; gentle haze | Sparse petals or young leaves |
| Summer | Dense deep greens; full ground cover | Stronger daylight; readable shaded greens | Restrained leaf drift and breeze |
| Fall | Species-specific amber, red, and brown; litter | Lower warm sun; golden haze | More falling leaves |
| Winter | Bare deciduous branches; retained evergreens; exposed snow | Cool sky fill; pale sun; warm interiors | Optional sparse snow; little leaf drift |
Choose particle effects only when they serve the scene. A seasonal selector does not require a storm or a full weather simulator.
Share one state
Use a four-component blend in the order [spring, summer, fall, winter]. Accept autumn as an alias for fall, then normalize to one internal key. The weights start nonnegative and sum to one.
const presets = {
spring: [1, 0, 0, 0], summer: [0, 1, 0, 0],
fall: [0, 0, 1, 0], winter: [0, 0, 0, 1],
};
const weights = [0, 1, 0, 0];
let target = presets.summer;
function setSeason(name) {
const key = name === 'autumn' ? 'fall' : name;
if (!Object.hasOwn(presets, key)) return false;
target = presets[key];
return true;
}
function stepSeason(dt, reducedMotion = false) {
const a = reducedMotion ? 1 : 1 - Math.exp(-1.4 * Math.min(Math.max(dt, 0), 0.05));
for (let i = 0; i < 4; i++) weights[i] += (target[i] - weights[i]) * a;
}Feed the same state into material uniforms, sky, sun/fill lighting, particle density, and optional ambient audio. A new selection should redirect the current blend, not queue another animation or reset to summer. Resolve each result from authored base values and weights; repeatedly tinting last frame's color causes drift.
Change foliage and snow convincingly
Use species-specific color palettes and stable per-instance IDs. Gradually thin deciduous foliage for winter using a deterministic threshold or dither. Preserve evergreen coverage. Apply matching visibility and wind rules to shadow/depth materials so absent leaves do not cast summer shadows.
For inexpensive settled snow, combine winter weight with upward-facing world-space geometric normals and an exposure mask:
snow = winterWeight * smoothstep(0.3, 0.85, worldNormal.y) * exposureBlend toward a pale, rough snow material. Upward normal alone also whitens sheltered tables and indoor floors; tag exposed objects or supply shelter masks. A material overlay does not add thickness or change silhouette. Add selective snow-cap geometry only for close-up edges where depth matters. Keep falling snow intensity separate from settled coverage if the scene models accumulation and melt.
Show full SKILL.md (196 more words)Show less
Keep the transition responsive
Preallocate particle pools and reuse materials/geometry. Change uniforms rather than recompiling shaders or rebuilding the world. Preserve existing material hooks when extending shaders and use stable program cache keys; match the installed renderer's shader chunks instead of assuming an old injection point exists.
Keep season independent of time of day and weather. Derive a final lighting state from those inputs once, so several controllers do not overwrite the same sun or fog values. Refresh expensive environment maps at controlled state changes, with caching where possible.
Use keyboard-accessible controls with a visible selected state and updated accessible labels. Under reduced motion, apply the chosen seasonal appearance immediately and retain a composed still scene. Pause continuous animation while hidden.
Verify
Capture all four seasons from the same camera. Each should be recognizable without its label. Rapidly switch spring → winter → summer → fall mid-transition and check for color drift, stale shadows, allocation spikes, and lost camera controls. Verify snow exposure indoors/outdoors, evergreen retention, particle count, and desktop/mobile rendering.
Read REFERENCES.md. Seijaku demonstrates shared uSeason weights, setSeason, snowInject, foliage thinning, and seasonal light tinting. Full snowfall physics and climate simulation are extensions, not claims about that implementation.
