About Corona

Corona is an architectural and design visualization tool used by top studios around the world.


Chaos Corona is a modern high-performance (un)biased photorealistic renderer, available for Autodesk 3ds Max, MAXON Cinema 4D, and as a standalone application.


The development of Chaos Corona started back in 2009 as a solo student project of Ondřej Karlík at Czech Technical University in Prague. Corona has since evolved to a full-time commercial project, after Ondřej established a company together with the former CG artist Adam Hotový and Jaroslav Křivánek, associate professor and researcher at Charles University in Prague.

In August 2017, the company became part of Chaos, allowing for further expansion and growth since that date. Chaos Corona continues to be developed by Chaos Czech a.s., a part of Chaos.

Corona’s popularity has grown year over year, thanks to its focus on delivering intuitive features that make our users’ lives easier, with innovations such as LightMix, Denoising, Interactive Rendering, and a Node Editor in the C4D version. We continue to look for more ways for our users to focus on being artists, not technicians.

In 2022, Chaos merged with Enscape. This will open up even more avenues for advancing the boundaries of rendering and content creation for those involved in design, architecture, and more.

2022 was also the year that Corona was rebranded, taking its rightful place alongside all the other Chaos products. This was more than just a new look, as it saw the introduction of Chaos Scatter, the inclusion of Chaos Cosmos along with Corona, and a new Premium tier subscription which includes Chaos Phoenix, Scans, and Player.

Present day

Today, Chaos Corona is a production-ready renderer capable of creating high–quality results. The latest version is currently available via our online shop.
