Quadify Bridge

Quadify Bridge is a Blender add-on that sends processed meshes from Blender directly into an Unreal Engine 5 project without manual FBX export. It works alongside the QSuite Bridge Receiver panel in Unreal to create a live Blender → UE5 pipeline.

How It Works

Bridge opens a local named pipe from the Blender side. When you click Send to Unreal, the active mesh is serialized, sent through the pipe, and received by the QSuite Bridge Receiver running in the Unreal Editor on the same machine. The mesh is imported automatically using the import settings configured in QSuite.

No files are written to disk and no FBX conversion occurs in the transfer path. The transfer is local-only — the pipe does not leave your machine.

Installation

Install __init__.py from the Bridge folder of your Quadify purchase into your Blender extensions directory: %APPDATA%\Blender Foundation\Blender\5.0\extensions\user_default\quadify_bridge\. In Blender, open Edit → Preferences → Extensions and enable Quadify Bridge. The Quadify Bridge tab will appear in the N-panel.

On the Unreal side, ensure QSuite is installed and the Bridge Receiver panel is open (see the QSuite docs).

Sending a Mesh

Select a mesh object in Object Mode. Open the Quadify Bridge N-panel tab. Confirm the target settings — import path in UE5, mesh name, and whether to apply modifiers before sending. Click Send to Unreal. The status indicator in the panel updates to Sending… then Received once the Bridge Receiver confirms the transfer.

If the Bridge Receiver is not running or the pipe is unavailable, the panel shows a Pipe unavailable — check Bridge Receiver error. Open the Bridge Receiver panel in Unreal and ensure it is in the Listening state before sending.

Settings

UE5 Import Path — Content Browser path in the Unreal project where the received mesh is placed. Defaults to /Game/Quadify_Bridge/.

Apply Modifiers — When enabled, all modifiers on the active object are applied before the mesh is transferred. Mirror modifier symmetry is preserved in the applied result.

Auto-Name from Object — Uses the Blender object name as the UE5 asset name. Disable to enter a custom name in the Asset Name field.

Transfer UVs — Sends all UV channels with the mesh. Disable if the asset will be UV-unwrapped in Unreal after import.

Recommended Workflow

The intended workflow is: retopologize in Blender using Quadify Ultra or Pro → unwrap UVs using Quadify Seam → send to Unreal via Bridge → run LOD Forge and Batch Processor in QSuite. This keeps all geometry work in Blender and all Unreal-side conditioning in QSuite, with the Bridge handling the transfer between them.

Troubleshooting

Pipe unavailable — Open the Bridge Receiver panel in UE5 and check it shows Listening. Restart the receiver if it shows Stopped.

Transfer stalls at Sending… — This usually means the receiver accepted the connection but UE5 is busy (e.g. a shader compile pass is running). Wait for the editor to become idle and try again.

Asset appears in wrong folder — Check the UE5 Import Path field in the Bridge panel. The path must begin with /Game/ and the folder must exist in the Content Browser before sending.
