About this release
Corona is a photorealistic renderer for 3ds Max that won its following by being straightforward where other engines are fiddly. The design goal is a clean, believable image with as little parameter wrangling as possible, so instead of a wall of sampling settings you light the scene, assign materials and let it resolve. For an architecture and interiors artist who wants to spend time on the look rather than the render settings, that simplicity is the whole appeal.
The interactive render is the tool you live in. It updates the image continuously as you move a light, tweak a material or nudge the camera, so lighting a room becomes a live conversation rather than a render and wait loop. The physically based material set is easy to reason about, the light setup mirrors how real lights behave, and features like the built in tone mapping and denoiser get you to a finished frame quickly and cleanly.
It fits into a 3ds Max pipeline as the render engine rather than a separate application, so scenes, cameras and modifiers all stay where they are. This build installs the plug-in in an activated state so the interactive render, the material library and the denoiser are all available from the first scene, and it slots alongside the modelling work without changing it.
What it does
- Photorealistic rendering with minimal parameter tuning
- Interactive render that updates live as you adjust a scene
- Physically based material set that is easy to reason about
- Realistic light setup mirroring how real lights behave
- Built in tone mapping for a finished look in the render
- Denoiser for clean frames with shorter render times
- Camera controls with real exposure, depth of field and bloom
- Scatter for placing large numbers of objects across a scene
- Render elements for compositing control in post
- Integrates as the render engine inside 3ds Max
Changes in this version
- Improved denoiser quality on interior scenes
- Faster interactive render startup
- Reworked tone mapping controls for finer look development
- Better memory handling on heavy scattered scenes
- Updated the bundled material library
What the package contains
- Chaos Corona for 3ds Max plug-in installer
- Bundled material library
- Readme with the install order written out step by step
- Notes on matching the plug-in to the 3ds Max version
- Sample scene showing an interior lighting setup
Installation notes
Follow these in order. Most reports of a failed install come from skipping a step rather than from the package itself.
- Close 3ds Max before you start.
- Disconnect from the network.
- Extract the archive to a short path such as C:\Setup.
- Run the plug-in installer as administrator and complete it.
- Open 3ds Max, set Corona as the render engine, then close it.
- Reconnect to the network.
System requirements
| Operating system | Windows 10 or Windows 11, 64-bit |
| Host application | A matching 3ds Max build must be installed |
| Processor | Intel or AMD multi core, more cores render faster |
| Memory | 16 GB minimum, 32 GB for large scenes |
| Graphics | GPU used for the viewport, rendering is processor led |
| Storage | 3 GB free for the install and library |
Things worth knowing
- This is a render engine for 3ds Max, not a standalone application, it runs inside Max.
- Rendering leans on processor cores, more cores cut render times more than a faster clock.
- Keep the plug-in matched to the 3ds Max version so it loads correctly.
Questions about this title
Is it a standalone renderer?
Why choose it over other engines?
Does the interactive render really update live?
Is rendering on the GPU or processor?
What people are saying
Lighting a room with the interactive render updating live is the whole reason I use it. Clean image, almost no settings to fight.
The denoiser on this version cut my render times noticeably on interiors. Frames come out clean.
More cores, faster renders, simple as that. Set it as the engine in Max and never looked back.
