Howto install a stable, non-experimental Blender/Yafaray package on Windows

It took me hours to figure out how to get Blender running with windows and yafaray. There are some more or less experimental Yafaray export scripts for the latest Blender 2.5x-series. But none of them is my cup of tee.

EDIT 18.07.2011

Forget about all the instructions below. Reading Yafaray’s Facebook page, which, btw, is an excellent ressource for advice, I found a link to some pre-compiled packages for all OSes:

Just download, unpack and start blender. No need to set any paths or pre-install python or whatsoever. You will then find YafaRay available by selecting the rendering engine from the menu bar:

Blender25 - Yafaray enabled

I’ve realized that for me it’s best to use the old version Blender 2.49a rather than the current 2.5x-series.

All in all, you need to get three components:

  1. Python 2.6.6 –
  2. Blender 2.49a –
  3. Yafaray 0.1.1 –

It is crucial to make use of precisely tjese versions, because all need to suite to the same python version.

Also, refer to in case you should run into any further problems.

Now here is what worked for me


  1. First, I installed Python 2.6.6. I set the PATH and the PYTHONPATH variable to point to the main install directory of Python
  2. I unzipped Blender 2.49a. Mind the [BLENDER_INSTALLDIR]/.blender/scripts directory
  3. I started the Yafaray 0.1.1 installed. When asked by the installer to choose the blender script directory, I located [BLENDER_INSTALLDIR]/.blender/scripts
  4. Starting Blender from the [BLENDER_INSTALLDIR], I had Blender found both, the Python and the Yafaray stuff 🙂
