Blender build for Raspberry Pi3?

I’m running the latest Blender 2.83.4 on a Raspberry Pi 3 B using Archlinux ARM AArch64. I’m only running it headless, so I don’t know the usability of it with the UI. I’m able to render images with Cycles as well as with Eevee or Workbench renderer with the help of xvfb.

You can also run Blender 2.82 in the official Raspberry Pi OS (64 bits) beta. You will need to add the buster-backports to the apt sources.list and then do:

sudo apt-get -t buster-backports install blender

As of June 16 2018, the current Blender version available for Raspian Stretch via apt-get is 2.78a. This is behind the current Blender 2.79c for other platforms.

You can install it with:

sudo apt-get install blender

It runs fine with full functionality, though it is slow. On a Pi 3 B+ it takes about one minute and 56 seconds to render the default scene (just the cube) in Cycles (using about 170MB of memory), so I wouldn't be planning to build a render-farm out of them lol.

It does use all four CPU cores while rendering in Cycles.

The biggest hurdle to getting Blender running on the Raspberry Pi is the fact that the Pi has an ARM processor rather than one that uses the x86 instruction set, which means software has to be specifically compiled for it. Currently the Blender Foundation does not provide these builds at the moment, but there are a number of builds floating around produced by 3rd parties that should work fine. Many of them mention use on the Pi since it is probably the most common normal linux ARM platform, the fact it runs full linux makes this much easier.

As you are relying on third party builds, many will be a bit out of date compared to the latest builds (certainly buildbot, and they may take a bit to catch up). That said on arch at least its up to date: https://archlinuxarm.org/packages?search=blender. However in the debian jesse repo, it is a fair bit out of date (https://packages.debian.org/jessie/blender). As fair as I'm aware the default Pi os (Raspbian) is based on jessie, so the blender you get there will be somewhat out of date. See @Zoots answer for more recent builds.

As Nathan Osman mentions in the comments, you should be able to install blender with: sudo apt-get install blender

For 2.8 and later, openGL 3.3 is required, making builds impossible. see https://blender.stackexchange.com/a/145057/26345
