The free halves, and the same for both editions.
The Cinema 4D plugin and the Blender add-on are free, whether you run Mesh Gate or Mesh Gate Lite on the Unreal side. You need one of them and the Unreal plugin — the modelling half on its own has nothing to talk to.
Version 1.0.0 · Windows · Cinema 4D 2026 or Blender 5.2+ · Unreal Engine 5.8
Installing
Unzip. You get two folders — c4d_livelink and
meshgate_fastpath.
Copy both into a Cinema 4D plugins folder, for example
%APPDATA%\Maxon\Maxon Cinema 4D 2026_<id>\plugins.
Restart Cinema 4D. Extensions → Mesh Gate opens the panel.
Unzip, and keep
Blender/meshgate_livelink-1.0.0.zip — do not unzip that one.
In Blender: Edit → Preferences → Get Extensions, then the menu at the top right → Install from Disk, and pick that zip.
The panel is in the 3D viewport's sidebar — press N to open it.
On the Unreal side, place the Mesh Gate Bridge actor in your level and the link comes
up. meshgate_fastpath is optional — without it Mesh Gate still works, it
just collects heavy meshes more slowly.
In the downloads
c4d_livelinkThe Cinema 4D plugin — the Mesh Gate panel, the object tag, materials, cameras, lights, cables, instances, the two-way side and the Python API.
meshgate_fastpathThe compiled C++ collector. It is why an 810,000-polygon object syncs in a fraction of a second instead of holding Cinema 4D for seconds.
meshgate_livelinkThe Blender add-on, as an installable extension. Streaming, materials, cameras, instances and the Python API, at parity with Cinema 4D apart from lights.
Every control, documented — in both downloads, and readable here without downloading anything.
You still need the Unreal plugin: Mesh Gate, or the free Mesh Gate Lite. Both are coming to Fab.
