Lifetime access to this resource, with its updates.

Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install threejs-motion-and-cleanup

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent builds a scene with a frame-rate independent loop, plays and blends GLTF animations, links the camera to scroll and renders thousands of objects with instancing. It delivers a single reproducible HTML file, checks it with screenshots at several moments, and disposes GPU resources properly.

Frequently asked questions

The text mentions a scripts/ folder. Is it needed?

No. Those helpers only capture check frames; the skill works without them using the Playwright command in the text.

Does it work with React?

Yes, it covers React Three Fiber (useFrame, ScrollControls, unmount cleanup).
