BCorona earns its place in the superhive library as a dedicated bridge from Blender to Chaos Corona's v3.0 Standalone renderer, bundling a Cycles material converter, default material presets, and documentation for the workflow.
BCorona is an unofficial add-on that exports scenes from Blender 3.0 or later into the Chaos Corona renderer v3.0 Standalone scene format. It targets the official free Standalone version of Chaos Corona v3.0, which you need installed for the exporter to work. The add-on runs on Windows only and is distributed under the GPL license.
Included is a Cycles to Corona material converter that handles basic shaders. Because Cycles and Corona use different shading approaches, the conversion covers only basic shaders, and default material presets are available for building Corona materials. Documentation is provided, and basic Geometry Nodes export is supported.
Several limitations come from the Chaos Corona v3.0 Standalone version itself. There is no particle system export, no Shadow Catcher, no Chaos Material Library, and no interactive viewport rendering like Cycles offers. Auto-smooth objects aren't exported directly; using an Edge Split or Weighted Normal modifier without Auto-smooth normals lets them export properly. Materials with textures applied in Material Preview won't preview there but appear when rendering.
Bcorona - Chaos Corona V3.0 Exporter For Blender 3.0 Or Later is best for blender artists on Windows who want to move their scenes into the Chaos Corona v3.0 Standalone renderer.
Bcorona - Chaos Corona V3.0 Exporter For Blender 3.0 Or Later is completely free to download and use.
BCorona supports a range of Blender releases through two builds. Version 2.4.2 covers Blender 4.2 through 5.1.x, while version 1.9.7 targets Blender 3.0 through 3.6.x. The listed Blender version support spans 3.0 to 5.0, and the add-on is marked as Blender Extension compatible. If you are on Blender 4.2 or newer, the 2.4.2 build is the one to use. Check the developer's page to confirm which build matches your exact Blender version before installing.
BCorona runs on Windows only. The add-on and its export workflow to the Chaos Corona v3.0 Standalone renderer are supported on Windows, with no macOS or Linux support listed. If you work on another operating system, this exporter won't fit your setup. For any changes to platform support, the developer's page and the community channels, such as the Telegram and Discord groups, are the places to check.
BCorona requires the official free Chaos Corona v3.0 Standalone version to be installed for the exporter to work correctly. The add-on outputs scenes in the Chaos Corona v3.0 Standalone scene format, so the Standalone renderer handles the actual rendering. Without it installed, exported scenes have nothing to open them. You'll also need Blender 3.0 or later and a Windows system. The developer's page lists these requirements alongside the download.
BCorona is listed as free in this catalog, and it is distributed under the GPL license. For current licensing terms and any purchase or download details, the developer's page is the place to check, since offerings can change over time. The add-on has been published for over three years and carries community support through its Telegram, Discord, and Facebook groups. Confirm the license and the version that fits your Blender setup before installing.
BCorona does not export particle systems, and only some basic Geometry Nodes export is supported. Several other limitations stem from the Chaos Corona v3.0 Standalone version itself, including no Shadow Catcher, no Chaos Material Library, and no interactive viewport rendering like Cycles. Auto-smooth objects don't export directly; an Edge Split or Weighted Normal modifier without Auto-smooth normals enabled exports them properly. The included Cycles to Corona converter handles only basic shaders, since the two engines use different shading approaches.
