But once the rendering has begun to be computed, you should get the final image much faster (generally twice as fast). As it depends on DLLs that must be included with the plug-in to support all these operating systems, it's much larger than other plug-ins, and it's slower to start than SunFlow rendering engine used in Sweet Home 3D.

After many tests and the feedback of volunteers, here's the version 1.0 of the YafaRay rendering plug-in (24 MB – See below for updates) able to run under Windows 32/64 bit (from Windows 7), macOS 64 bit (from Mac OS X 10.8) and Linux 32/64 bit (from Ubuntu 16). Following a performance study of the rendering engines able to run within Sweet Home 3D, I decided last year to develop a new plug-in based on YafaRay rendering engine.
