Yafray hack: Accelerated Photon Map Rendering


yafray logoRCRuiz has posted a hack that speeds up Photon Map rendering in Yafray a great deal. It's a bit thin on the details but it would seem that he stores the photon distribution in your scene so that you can quickly re-render it from any camera angle and position.

As long as you don't move any objects or lights this should work fine. For many types of fly-through animation, such as architectural walkthroughs, this will be a great timesaver.

The downloads and instructions can be found on Elysiun.

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.
