Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

# Using Three.js and React Three Fiber in Remotion
|
|
|
|
Follow React Three Fiber and Three.js best practices.
|
|
Only the following Remotion-specific rules need to be followed:
|
|
|
|
## Prerequisites
|
|
|
|
First, the `@remotion/three` package needs to be installed.
|
|
If it is not, use the following command:
|
|
|
|
```bash
|
|
npx remotion add @remotion/three # If project uses npm
|
|
bunx remotion add @remotion/three # If project uses bun
|
|
yarn remotion add @remotion/three # If project uses yarn
|
|
pnpm exec remotion add @remotion/three # If project uses pnpm
|
|
```
|
|
|
|
## Using ThreeCanvas
|
|
|
|
You MUST wrap 3D content in `<ThreeCanvas>` and include proper lighting.
|
|
`<ThreeCanvas>` MUST have a `width` and `height` prop.
|
|
|
|
```tsx
|
|
import { ThreeCanvas } from "@remotion/three";
|
|
import { useVideoConfig } from "remotion";
|
|
|
|
const { width, height } = useVideoConfig();
|
|
|
|
<ThreeCanvas width={width} height={height}>
|
|
<ambientLight intensity={0.4} />
|
|
<directionalLight position={[5, 5, 5]} intensity={0.8} />
|
|
<mesh>
|
|
<sphereGeometry args={[1, 32, 32]} />
|
|
<meshStandardMaterial color="red" />
|
|
</mesh>
|
|
</ThreeCanvas>;
|
|
```
|
|
|
|
## No animations not driven by `useCurrentFrame()`
|
|
|
|
Shaders, models etc MUST NOT animate by themselves.
|
|
No animations are allowed unless they are driven by `useCurrentFrame()`.
|
|
Otherwise, it will cause flickering during rendering.
|
|
|
|
Using `useFrame()` from `@react-three/fiber` is forbidden.
|
|
|
|
## Animate using `useCurrentFrame()`
|
|
|
|
Use `useCurrentFrame()` to perform animations.
|
|
|
|
```tsx
|
|
const frame = useCurrentFrame();
|
|
const rotationY = frame * 0.02;
|
|
|
|
<mesh rotation={[0, rotationY, 0]}>
|
|
<boxGeometry args={[2, 2, 2]} />
|
|
<meshStandardMaterial color="#4a9eff" />
|
|
</mesh>;
|
|
```
|
|
|
|
## Using `<Sequence>` inside `<ThreeCanvas>`
|
|
|
|
The `layout` prop of any `<Sequence>` inside a `<ThreeCanvas>` must be set to `none`.
|
|
|
|
```tsx
|
|
import { Sequence } from "remotion";
|
|
import { ThreeCanvas } from "@remotion/three";
|
|
|
|
const { width, height } = useVideoConfig();
|
|
|
|
<ThreeCanvas width={width} height={height}>
|
|
<Sequence layout="none">
|
|
<mesh>
|
|
<boxGeometry args={[2, 2, 2]} />
|
|
<meshStandardMaterial color="#4a9eff" />
|
|
</mesh>
|
|
</Sequence>
|
|
</ThreeCanvas>;
|
|
```
