B2ULink
A practical asset bridge from Blender to Unreal Engine.
Author reusable structures in Blender, export the full asset package, and send updates to the Unreal Editor you already have open.

What it handles
One pipeline, not six disconnected chores.
Unreal updates
Detect a running Unreal Editor on Windows and execute imports, reimports, material setup, and placement remotely.
LOD workflow
Author up to eight LOD collections, preview screen sizes, generate decimated LODs, hulls, boxes, and imposters.
Collision
Create UBX, UCP, USP, UCX, or a separately imported complex collision mesh from selected geometry.
Materials & textures
Carry material targets, parameters, texture settings, and supported Blender node graphs into Unreal.
Scene placement
Write direct collection instances and Geometry Nodes instances with transform, custom depth, and stencil data.
Core flow
From source asset to placed actor.
- 01
Create a structure
B2ULink creates the named Main collection, Parent, LOD0–LOD7, collision, socket, asset, and dump collections.
- 02
Author the asset
Keep the production mesh in LOD0, add optional LODs and collision, then choose the Unreal content path and import settings.
- 03
Export & update
The bridge writes FBX and import data beside the .blend file, then executes the matching import and placement work in Unreal.
