An efficient and visually pleasing implementation of SSAO with an emphasis on temporal stability and artist control.

> We recommend using the [ES6 package `@babylonjs/core`](https://www.npmjs.com/package/@babylonjs/core) for new projects. This UMD package is provided for compatibility.

The Babylon Inspector is a diagnostic tool that makes it possible to view and edit the scene graph, properties of entities within the scene, and more.

Zero-dependency declarative pixel-art engine: JSON scene documents (layers, palette, sparse pixel overrides) rasterized to RGBA and PNG, with inspection tools for LLM-driven construction, plus an animation subsystem (frames, exact diffing, region validati

Lightweight, GPU-free video composition + rendering engine: a JSON scene-graph IR, CanvasKit/Skia (wasm) or native (Rust + skia-safe) renderer, and an FFmpeg encoder — with a CLI for scripted/agent use.
