Game-First Physics Stack

A purpose-built physics runtime with deterministic networking hooks, smart BVH contact resolution, and camera brains tuned for controllers or touch. It's almost 4 years of continuous internal development that all started here: https://x.com/utsuboco/status/1441730683743789057?s=20

• • Character controller presets for third-person, platformer, rigid, kinematic and static bodies.
• • Cinematic camera stack with blend trees and collision-aware framing.

Starter · Game Engine

A modular foundation for shipping real-time, game-like experiences in seconds.

• • Custom physics core with avatar, vehicle, and camera presets.
• • Indirect batched, skinned mesh avatar pipeline from Blender to production.
• • Liveops-friendly perks system inside the Three.js Blocks tools.
• • Open-world ready asset streaming with region-aware triggers.

Animation Object Texture

Advanced tool to bake multiple animation object texture, ultimately allowing to export and bake complex animation from software such as Blender that would weight hundreds of mb and renders thousands of instances into InstancedMesh and a GPU Compute based Animation Mixer.

Starter CLI

Interactive CLI that assembles starters based on engine, aesthetic, and platform preferences.

• • Stacks for R3F, Vue, or core Three.js with opinionated build defaults.
• • Guide mode that scaffolds scenes, materials, and data integrations.

Geometry LOD Tool Generator

Author, preview, and deploy multi-LOD assets in a dedicated format that accelerates cold starts for large experiences.

• • Batch convert source meshes, textures, and impostors with watch-mode automation.
• • Deliver signed manifests to CDN and runtime with a single command.

Alpha Channel Setup

Controlled release program for Pro teams to trial upcoming Blocks before general availability.

• • Per-project feature flags with fast rollback.
• • Feedback loop wired directly into roadmap triage.

Starter · Smooth 3D Scroll

A storytelling template that keeps scroll, 3D scenes, and interface transitions perfectly in sync.

• • Baseline choreography tuned for GPU-heavy scroll-linked animation via offscreen canvas support.

Game Physic Engine - Multiplayer Support

Add multiplayer support in the Game Physic Engine.

Meshlet Tool Generator

Generate serial graph partitions via METIS with preview tooling so teams tune meshlets before shipping.

• • Advanced visualizer for cluster density, overdraw, and memory footprints.

Automation Tests

Automated regression runs that catch rendering and API issues before they reach production teams.

• • Examples issue detection via Puppeteer.
• • Headless integration tests across core Blocks packages.
• • CI hooks that block releases on performance or API regressions.
