YafaRay is a free open-source montecarlo raytracing engine released under the LGPL 2.1 license. Raytracing is a rendering technique for generating realistic images by tracing the path of light through a 3D scene. A render engine consists of a specialised computer program that interacts with a host 3D application to provide specific raytracing capabilities "on demand". The YafaRay engine can be used in the following 3D applications: Blender, Edificius, pCon-planner and Wings 3D.

You can download YafaRay binaries and the source code in the downloads section.

We would like to announce the release of the new version v3.1.1-beta. We hope you like it!

https://github.com/YafaRay/Blender-Expo ... 3.1.1-beta

You can download builds for Linux 32/64bit (this time hopefully without the issues that the v3.0.2 builds had), Windows 32/64 bits and MacOSX 64bits (however the Mac build needs additional tests, as we only can do *very* limited tests for the Mac builds)

Please if you have any issues with it, let us know in the Bug Tracker and/or Forums.

After several months of work we are happy to announce the release of the new YafaRay 3.0.2-beta for Blender v2.77a. We have prepared builds for Linux 32/64bit, Windows 32/64bit and MacOSX Intel 64bit. Windows XP support has been dropped due to the new Python 3.5 OS requirements. The MacOSX version has been tested only a little bit due to severe hardware restrictions. You can see all the changes respect to v2.1.1, download the builds and an example test scene from:

I've uploaded YafaRay-E v2.0.2 with some fixes respect to v2.0.1:

  • Fixed crash when Blend materials were used and their components were also blend, which had some component materials missing
  • Max value for the dark noise factor parameter expanded to 1.0 to allow even darker areas to have better AA sampling
  • Fix for Oren Nayar to avoid generating white/black dots when used together with bump mapping
  • Fix for black dots using HDRI spherical and Coated Glossy
