Coming soonHunyuan 3D 3.1 + PicoBerry API

Unreal Bridge

Send a finished 3D asset from PicoBerry straight into Unreal Engine with one click — no file download, no API key.

The Unreal Bridge sends a 3D asset from your PicoBerry workspace straight into Unreal Engine — one click, no file to download and re-import. Like the Blender Bridge, it runs entirely on your own machine: there's no API key and no paid lock, so anyone on any plan can use it.

Install the plugin

  1. Download the plugin (a .zip) from the Send to DCC menu in your PicoBerry workspace.
  2. Extract it into your Unreal project's Plugins folder (create the folder if it doesn't exist).
  3. Open your project. If Unreal asks to enable the plugin, choose Yes.
  4. Confirm PicoBerry Bridge is enabled under Edit → Plugins.

Connect Unreal to PicoBerry

The plugin starts a local listener automatically when the editor loads.

  • In Unreal — the bridge listens on your machine (ports 60611–60620). No window or sign-in is needed.
  • In PicoBerry (your browser) — open a 3D asset and click the send (paper-plane) menu in the toolbar. When the Unreal row reads Connected (green), you're ready to send. Until it connects, that row shows an Install link instead.
Before connecting — Install link on the Unreal rowConnected — the Unreal row reads Connected and sends via the paper-plane

Send an asset to Unreal

  1. Open a finished 3D model in your PicoBerry workspace.
  2. Click the send (paper-plane icon) in the toolbar to open the menu.
  3. When the Unreal row reads Connected, click that row (or the paper-plane icon on the right).
  4. A progress toast appears while the asset downloads and imports.
  5. In Unreal's Content Browser, the model shows up under PicoBerry / <name> — mesh, materials, and textures together — and is placed into the open level.

Troubleshooting

The send menu never shows Connected / it won't connect.

  • Make sure the PicoBerry Bridge plugin is enabled in Edit → Plugins, and that the Python Editor Script Plugin is also on.
  • If you opened PicoBerry before Unreal, the page may take a moment to find it on its own. Switch to another tab and back, or reload the page, to rescan right away.
  • Confirm you're on Unreal Engine 5.4 or newer.
  • Check that no other program is using ports 60611–60620.

Still stuck?

  • Check the editor's Output Log (filter for PicoBerry) to see what the plugin recorded, then reach out to support with that detail.
