Released in 2021, initially as a free tool and later as a paid add-on, BCorona allows rendering scenes created in Blender using the Corona renderer instead of its native rendering engine, Cycles. Its primary application is in architectural visualization, for artists who have transitioned to Blender as an open-source solution for 3D modeling but want an architecture-focused renderer. Instead of the commercial version of Corona, it works with Corona Standalone, a GUI-less rendering version that can be downloaded for free; however, it's worth noting that the last update was in 2019. Since Corona Standalone is not designed for use with a graphical interface, it doesn't provide an accurate preview of materials in the render viewport, although the final quality should be displayed correctly.

It also supports path tracing but not UHD Cache, a displaced global illumination solver in Corona that is often used to speed up rendering interior scenes. Additionally, BCorona has its limitations, the main ones being that it doesn't support popular geometric nodes and particle systems in Blender. However, it is capable of producing decent renders, as evidenced by images shared in the support thread on the Blender Artists forum.
Apart from the mentioned aspects, BCorona 2.0 is the latest version of the plugin, introducing a new experimental converter to translate Cycles shaders into Corona: a demo of the early version can be seen here. The update also includes support for Blender 4.0, the current version of Blender.

BCorona 2.0 is compatible with Blender 4.0 and later, and it operates exclusively on Windows. It is priced at $40. The plugin's version 1.9.5, supporting Blender 3.x, is still available and costs $25. BCorona can be used in conjunction with Corona Standalone 3.0, which is available for free.
