YafaRay 3.4.4

YafaRay is a free open-source physically based 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.

Recent Releases

3.4.413 May 2020 09:45 minor feature: YafaRay v3.4.4 (2020-05-09) Angular camera: modified to add several types of angular projections and to new ortographic calculations.
3.4.209 May 2020 10:25 minor feature: YafaRay v3.4.2 (2020-05-08) Added Equirectangular camera. Triangle: added "mesh- gt;normals_exported" condition to enable user. defined normals.
3.4.109 Apr 2020 20:25 minor feature: YafaRay v3.4.1 (2020-04-08) Changed documentation to state that any reporting and resolution will solely be done in the GitHub Project "" tab. in the old yafaray.org tracker will not be processed anymore. Added note about Blender-Exporter only working for Blender v2.7x versions.
3.4.029 Mar 2020 02:45 minor feature: YafaRay v3.4.0 (2020-03-22) Note: don't mind the release date, the project has been mostly inactive for a long time, so only a few (although significant) changes since v3.3.0, but it was about time to give the last changes a proper release version number. Feature changes/additions: New per-material transparency bias for Shiny Diffuse. When there are objects with many transparent surfaces stacked together (such as leaves in a tree) sometimes black artifacts appear if the ray reaches the maximum depth. This can be solved by increasing the maximum ray depth, but the render times increase. I've added two new parameters for the Shiny Diffuse material to try to achieve a "trick", which is not realistic and may cause other artifacts but that should prevent the black areas without having to increase the maximum ray depth so much. Dependencies changes: IMPORTANT: Migration from Qt4 to Qt5 as Qt4 reached End of Life. Dependency on meganz/mingw-std-threads made optional, because it's needed for old MinGW compilers but it causes conflicts with new MinGW compilers, so better to have it as an option in CMake. Compatibility for Python 3.8. Other changes: Silenced some warnings while building in recent versions of gcc.
3.3.025 Sep 2019 18:31 major bugfix: Feature changes/additions: -------------------------- * "Flat Material" option added to Shiny Diffuse, requested by a certain user. Flat Material is a special non-photorealistic material that does not multiply the surface color by the cosine of the angle with the light, as happens in real life. Also, if receive_shadows is disabled, this flat material does no longer self-shadow. For special applications only. Bug fixes: ---------- * Bidirectional: fixed transparent background not working, was causing the entire render to have transparent alpha. See: http://www.yafaray.org/community/forum/viewtopic.php?f=15 t=5236 * Bidirectional: fixes (horrible hacks in fact, but...) for unitialized values causing incorrect illumination in scenes * Fixed hang in Windows 7 when YafaRay is built using Visual Studio 2013. * Some building fixes
