[citation needed] Corona is provided as a plug-in for Autodesk 3ds Max and Maxon Cinema 4D, and a standalone GUI-less application.
He was later joined by a former CGI artist Adam Hotový, and Jaroslav Křivánek, associate professor and researcher at the Charles University in Prague, and founded the company Render Legion.
[5] He planned to create Corona Renderer for Blender, but it was impossible to launch a commercial product due to the restrictive GNU GPL license, so the development focused on Autodesk 3ds Max.
[8] Corona has three rendering options: Progressive (which refines the whole frame to the desired quality), Bucket (which makes numerous passes, refining the buckets where it's needed, notably reducing rendering time in scenes with large uniform areas), and BiDir/VCM mode (for scenes that need clear caustics).
For instance, Chaos Corona 8 (2022) includes Cosmos (a library of curated render-ready models with comprehensive materials, such as furniture, trees, cars, and people, as well as HDR sky images); materials library and materials editor;[9] conversion tools that simplify import of scenes, lights, objects, and materials from V-Ray, Mental Ray, and finalRender; its own set of lights and a physical camera (which allows controlling ISO, aperture, shutter speed, depth of field, and focus distance);[7] tools for plausibly randomized objects and effects placement; and so on.
