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

David has released a new version of the YafaRay-E (Experimental) testing branch. There are builds available for Windows 32/64bits, Linux 32/64bits and Mac OSX 64bits (version 10.6 or higher). You have the description about the new version and the download links here.

We have prepared a new YafaRay Experimental version 1.0.0 with builds for Windows 32/64 bits and for Linux 32/64 bits, tested with Blender 2.76. Main changes and fixes are:

  • Fixes to the Color pipeline and linear workflow. Better Color Management integration with Blender.
  • Fixes to Volumetrics and their inclusion in the Recursive Raytracing process so now they are correctly reflected and refracted like other objects, which fixes an old problem when mixing transparent objects with volumes.
  • Fixed some artifacts with bump mapping.
  • New per-material "visibility" parameter that allows fully visible materials, materials without shadows, materials "shadow only" and fully invisible materials.
  • New per-light enable/disable function and "cast shadows" option, so we can choose if we want each light to cast shadows or not.
  • Other fixes for white dots, and other issues.

More detailed information and download links here. As an experimental version, it could have new and unexpected issues so please let us know if you have any problems. Use the thread linked above and/or the bugtracker to report problems and issues.
