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.

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

Hello all!

I want to wish you a very Happy New Year 2016. Also, a new year deserves a New YafaRay. I would like to announce the new YafaRay-E (Experimental) v2.0.1

A lot of work involved and many changes, so I would expect some bugs (hopefully not too many). The main changes are the implementation of Render Passes and Render Views, but there are more that I will try to explain more over the next weeks with some examples I will prepare and upload over time.

The full ChangeLog and download links are here with builds for Linux 32bit/64bit,  Windows 32bit/64bit and Mac OSX 64bit:

I hope you enjoy it,

David Bluecame
