B2ULink documentation
Overview
B2ULink is a Blender asset-authoring and Unreal update pipeline built around predictable structures instead of one-off export steps.
What B2ULink does
The addon creates a complete Blender collection structure for a reusable Static Mesh asset. That structure can hold LOD0–LOD7, sockets, simple collision, complex collision, and shared asset references.
The Unreal Bridge exports the current asset state beside the saved .blend file, finds a running Unreal Editor, and executes the import or reimport inside Unreal through Python Remote Execution.
- Generate and validate repeatable asset collection structures.
- Export combined FBX assets with LOD data and Unreal import settings.
- Import or reimport textures, materials, sockets, collision, and LOD screen sizes.
- Write direct collection instances and Geometry Nodes instances as Unreal level placement data.
- Generate LODs, bounding boxes, convex hulls, imposters, and collision helpers inside Blender.
