DSH Dafeiyu Assets: Transparent Motion & Manifests

Pet code can be reused, but character quality depends on disciplined assets. Inconsistent anchors, broken loop endpoints, and green transparent edges make a character look like a video pasted onto the screen rather than a resident of the desktop.

The community dsh-pet project publishes a complete route from prompts and green-screen video to transparent animation, plugin configuration, and release. This guide turns that process into a market-ready character-pack workflow.

Define a minimum motion set

Begin with six semantic states:

Click, head pat, drag, and feeding are temporary interaction layers. They must not replace authoritative Agent state; after playing, return to the latest Host snapshot.

Keep the character consistent at generation time

Every generated motion should share a template: fixed aspect ratio, camera, character size, and foot baseline; a background distinct from the character; no motion outside the frame; similar start and end poses; consistent clothing, tail, headpiece, and colors; preserved prompts, seeds, source video, and generator version.

For a bottom-edge pet, foot anchoring matters more than visual centering. A changing baseline makes the character float during transitions.

Convert green screen to transparent animation

A practical pipeline is:

1. key every frame;
2. remove green spill and repair semi-transparent edges;
3. normalize canvas size or record per-frame anchors;
4. remove duplicate frames and wasteful bitrate;
5. export alpha WebM, PNG sequences, or atlases;
6. inspect edges over light, dark, and complex backgrounds.

WebM is simple to package; atlases provide precise frames and transition control; Live2D is more expressive but introduces separate model, texture, motion, and physics licenses.

Character manifest

A pack should identify itself, renderer, anchor, version, and state assets:

{
  "id": "my-dafeiyu",
  "name": "My Dafeiyu",
  "version": 1,
  "renderer": "webm",
  "anchor": { "x": 0.5, "y": 1 },
  "states": {
    "idle": ["idle.webm"],
    "thinking": ["thinking.webm"],
    "working": ["working.webm"],
    "waiting": ["waiting.webm"],
    "success": ["success.webm"],
    "error": ["error.webm"]
  }
}

Use the real schema of the target runtime. Also describe loops, enter/exit segments, weights, cooldowns, audio, subtitles, and asset licenses.

Performance budget

Pause rendering when hidden, avoid high-rate idle repaints, load each state once, defer large audio and video, provide reduced-motion and static alternatives, and allow low-end devices to disable particles, shadows, and live blur.

A market page should disclose package size and typical CPU/GPU and memory behavior, not only a showcase video.

License every layer

MIT or Apache-2.0 code does not grant rights to character art, generated video, voice, font, or music. Dafeiyu derivatives may also carry attribution, noncommercial, and share-alike obligations from earlier designs.

List code license, character origin, derivative and generation notes, voice/music/font terms, and whether commercial use, redistribution, reskinning, and training are allowed.

Next connect the motions to the DSH Session and Tool Call state machine, or start with the build-your-own Dafeiyu guide.
