Opensource Blender addon and distributed cloud rendering system.


  • Idea & realization: Rabit


Please check out the wiki page: Wiki


  • Blender >= 2.80
  • GCP Provider: Google Cloud Platform project and google cloud sdk
  • AWS Provider: Amazon Web Services account and aws cli v2
  • Local Provider: no reqs


Existing blender addons, that enabling network rendering on a cluster of instances are too complicated, not enough automated or too expensive. The solution is just to use the existing cloud providers with their cheap preemptible instances costs ~3 times less than the regular ones.

For example GCP n1-highcpu-64 (64 core 57.6GB RAM) will cost you just $0.48 per hour. Just imagine this - a quite complicated Cycles engine frame will cost just $0.50.


The system consists of 3 main parts:

  • Addon - blender interface to simplify run and manage the tasks
  • Manager - controls Agents, merges results, provides status to Addon
  • Agent - worker of the system, rendering task, provides status to Manager

All the components are using HTTPS & Basic Auth to protect the connection.

  • Dynamic preview - user can see the progress of rendering, picture updated every 5s (default)
  • Non-destructive preview engine - you can close preview and open it again without interrupting
  • Allow to create providers - right now supported local run & GCP
  • Saves your money - if some resources are not needed right now - they will be terminated


You can see all the feature requests/bugs on the github page:


  • Use buckets to cache dependencies/results
  • Cost estimation before rendering
  • Distributed smoke baking (per-domain): it’s hard to bake multiple domains - it requires one domain per bake, others should be turned off
  • Allocating of preemptible GPU on the instances
  • Detailed statistics to optimize the pipeline
  • Simplify the setup process for the end-user
  • Web interface to check the status


This is an experimental project. The main goal is to test State of the Art philosophy in practice.

We would love to see independent developers working on the project’s issues: for fun and interest as well as for monetary compensation (say, attached to the tickets).


The repository and its contents are covered by Apache v2.0, so anyone can use it without any concerns.

If you have any changes you’d like to share, don’t hesitate to make a pull-request and push them into the original repository. Definitely no pressure though.


There is no need to build the project, just download zip archive with the latest release from GitHub and install the addon using Blender add-on installer.
