Ubisoft releases 'Mixer' Collaboration Add-on for Blender


The Mixer add-on, which has been released as alpha code on GitHub, allows Blender users to work together in one scene. This can be both on a local network, but also remotely (in which case you'll need to do some network setup).

It works by creating 'rooms' on the Mixer server that you can join for specific projects.

Ubisoft writes:

Mixer is a Blender addon developed at Ubisoft Animation Studio for Real Time Collaboration in 3D edition. It allows multiple Blender users to work on the same scene at the same time. Thanks to a broadcasting server that is independent from Blender, it is also possible to implement a connection for other 3D editing softwares.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. this Mixer and another addon called multi user are most important addons for blender ever i saw in my ~ 7 years of "blender life" and i following every day blender news, addons, development and etc...

    tryed them both now and looks like both addons and both addons missing very little to be perfect ! so super exiting times awaiting with that multiplayer blender... i saw both addons are beeing developed very actively.

    i only dream now they would work together for faster development
    i really think blender devs should immediatly start help / develop it too since this is even much more bigger of importance than any new blender feature ever i saw...

    so for everyone i say just try this MIXER and MULTI USER addons since they unbelieveable revolutionary AMAZING !!!

    • Blender actually had an addon that did this about 12 years ago called Blender Verse. It was alpha stages but they released a build with it 2.47 or 2.48. I'm super excited to see this again.

  2. anyone have a video or a walk through on how to get this to run, I am trying with a friend adn we dont know how to connect to each other or if we have to setup a server

      We're getting there. Blender still needs friendlier support of some standards like FBX--or the industry will need to adopt newer standards to replace FBX soon.

      That will take time. Sadly, Autodesk pipelines are still king. Both in 3D-related education and professional industry.

      But this is a great step towards industry-wider adoption of Blender-based pipelines. So good to see more and more powerful steps taken by major companies in Blender's favor.

      • FBX is a disaster. Blender has more friendlier support for this ugly format than, say, Houdini. Looking forward to better Alembic support (like line rendering), and full USD support.

          Oh, I do 100% agree! But FBX is still in heavy use, industry-wide. Particularly in fields like game dev (which, of course, Ubisoft does).

          Newer, better formats (such as Alembic) are around and emerging, but it takes a little time to wean schools and businesses alike off heavy dependency on Autodesk's proprietary nonsense.

          The transition from Autodesk-dependency to Blender pipelines will be more like a growing process than a "dumping" of Autodesk, is what I'm saying.

          But, boy, are many people ready! ;)

          • Totally agree. Despite is flaws, FBX did much to popularize 3D, mainly for gamedev. BTW a fun fact - official Autodesk FBX Converter software is broken, can't even properly export complex hierarchies without messing up pivots.

  3. I have just tried it after i saw this message, and this software is really cool. it's bloody fast simple &d fun to use... it's odd there's no info about anywhere?

  4. Looks kool! But setting up a network to use online sounds a bit tricky. Have you heard of Massless Space? Someone mentioned it in a Discord channel... multi-user synchronizing between Blender, Unity and Chrome.
