Here's a new Blender renderfarm project, all open source.
during the last two semesters I was developing a Renderfarm especially for Blender, to be used within my university. It is focused on an easy setup and comfortable use. The software is written in C++, utilizing the great cross-platform Qt Framework and some libraries for video creation (FFMPEG) and security (OpenSSL).
We used it mainly for rendering stereoscopic 3D in 4K, which was not possible with Blenders internal renderfarm. This project was an attempt to make this possible, while using Blender in the background. Moreover, it is possible to use it for distributed tile rendering, for example if you'd like to render a big image over the network of several computers.
Here is a little teaser:
The development is still in the alpha phase, but it might be useful for someone.
This is the project website, where you can download GSORF and look at the documentation.
The source code is licensed under the GNU GPL license, so feel free to download and compile.
You can also donate, if you like. I'd love to then use the donations to support the Blender Foundation in turn.
Thank you and Cheers,
