TriSync — Live sync from Blender to Unity

TriSync is a Blender add-on and Unity Editor companion for live synchronization of 3D content between Blender and Unity.

It is a development tool, not a standalone game, player build, or HTML5 application.

Features

• Import and update meshes, materials, and textures
• Support for UV0 through UV7, normals, vertex colors, and triangle topology
• Transform, hierarchy, visibility, and scene-state synchronization
• Shape Keys and Unity BlendShapes
• Rigged objects, skinning, and bind poses
• Animation Clip import and export
• Geometry Nodes mesh workflows
• Unity Mesh extraction to Blender
• Humanoid Avatar and Root Motion tools
• Unity Registry and diagnostics tools
• English and Simplified Chinese interface support

Blender and Unity communicate through a local WebSocket connection. No cloud service or online account is required.

Requirements

• Blender 4.2.x through 5.2.x
• Unity Editor 6000.0.x through 6000.5.x
• Universal Render Pipeline 17.0.x through 17.5.x
• Unity and URP minor versions must match, for example:
  • Unity 6000.3.x with URP 17.3.x

The Blender add-on includes optional native mesh helpers for:

• Windows x86_64
• Linux x86_64
• macOS arm64
• macOS x86_64

If the native helper cannot be loaded, TriSync automatically uses its Python implementation. The feature remains functional, but large mesh operations may be slower.

Windows x86_64 is the fully qualified platform. Linux and macOS native artifacts are included, but their full interoperability coverage is more limited.
