Corona 12 Release Notes Corona to Vantage scene export
Corona 12 supports scene export to Vantage, a high-quality visualization environment enabling 3D artists to swiftly explore and showcase their work in a fully ray-traced setting. This integration empowers Corona users with active Vantage licenses to flexibly choose between CPU and GPU rendering workflows based on their hardware and project requirements, significantly accelerating scene exploration and rendering.
With this initial integration, you can export your Corona scenes in .vrscene format and open them in Vantage. Once in Vantage, you can explore your scenes by navigating them in real-time and rendering images in seconds. This is ideal for faster scene exploration, test renders, and even final renders when full photorealism is not required. For full realism, you can switch back to Corona and render those scenes on the CPU by replicating the camera angles you discovered in Vantage.
It's also possible to import your Corona scenes into Vantage to create animations using Vantage’s animation features, benefiting from the lightning-fast speed of GPU rendering.
The second stage of the Corona and Vantage integration will enable a live link between the tools, allowing you to render animations created in 3ds Max and Cinema 4D in Vantage. This is expected with Corona 13 towards the end of 2024, so stay tuned!
Curved Decals
Curved Decals allow you to perfectly bend labels to round or curved objects such as bottles and cups without any distortions and with incredible ease. Labels can be bent up to 360 degrees to map a pattern around an object. In addition, decals can now be bent around a second axis, allowing you to add decals to spherical objects like balls, balloons, and more. Additionally, a toggleable lock button has been added that locks the width-to-height aspect ratio for the Decal.
New Virtual Frame Buffer (VFB 2)
With Corona 12, we are introducing an improved version of the Virtual Frame Buffer (VFB) with a more intuitive UI and many new features.
With VFB 2, you can:
- Drag and drop a Corona EXR (CXR) file into the VFB itself and immediately continue editing it, even without the original scene being loaded in 3ds Max or Cinema 4D.
- Easily compare images with different resolutions and aspect ratios using the new A/B comparison option.
- Enjoy a smoother workflow by having multiple LightMix elements where each one has its own settings. This allows you to save different lighting setups (e.g., night and day) in one image instead of having separate configuration files for each LightMix setup. You get more information in one file and keep things tidier.
- Speed up the iteration process and save valuable processing time by choosing to defer the calculation of bloom and glare until the end of the render.
- Use new Gamma, Lift, and Gain parameters for tone mapping.
- Enjoy a more polished look and a snappier performance of the UI.
- And more!
VFB 2 also brings history management improvements and other smaller enhancements that make it more intuitive and easy to navigate.
Corona Pattern improvements
With the new Corona Pattern improvements, you can now use a geometric object as a helper to define the crop box, letting you use vertex editing and snapping tools to easily cut out the pattern geometry without any resulting glitches, holes, seams, etc. Also, in Corona for 3ds Max (and as soon as we can for Cinema 4D), you can create materials that were previously impossible. You get the flexibility of choosing whether the maps follow the base object UV, the pattern object UV, or both.
For example, if you are working on a blanket or other textile material, you can have one bump map for wrinkles mapped across the entire base UV of the blanket while the individual pattern segments repeat a diffuse pattern. Or you can repeat the color by pattern and mix it with an overall color across the base object, such as an image of a blanket mixed with various colored fibers.
Additionally, in both 3ds Max and Cinema 4D, you can now define the visibility of the pattern using a shader to create holes or gaps in the applied pattern, automatically generate caps over holes created by the slicing of the Pattern Crop Box, and more easily see the direction that the pattern will be applied thanks to a normal direction indicator on the Crop Box which shows the direction that will face “outward” when applied to the base object.
With the help of Corona Pattern, you can achieve much more realistic results with just a few simple clicks.
Scatter Instance Brush (Corona for 3ds Max)
Another great new feature in Corona 12 for 3ds Max is Scatter Instance Brush, which gives you further creative control over the scattering process. It allows you to refine a procedural scatter to get the exact results you want.
Using a brush, you can now delete procedural instances or paint in new ones to achieve maximum realism. At the time of painting in instances, you can choose whether those instances are affected by the scatter rules of altitude, slope, and spline include/excludes - or not! Scatter Instance Brush will be implemented in Corona for Cinema 4D as soon as we can.
Corona Sky improvements
Fading in from day to night has never been better. The improved Corona Sky supports even lower angles for sun below the horizon (down to -12 degrees, compared to the previous -4.2 degrees), which makes day/night animations and still images more realistic and immersive.
Corona Sky also now includes a Density parameter — lower it to make your clouds thin and wispy all the way down to invisible, or raise it to make them dense and thunderously heavy.
Smaller improvements in Corona 12
Cryptomatte sees a couple of improvements, allowing you to set up Cryptomatte by material, and additionally the Cryptomatte render element now works correctly in Distributed Rendering (3ds Max) and Team Render (Cinema 4D), and when using Resume Render.
Material conversions have been improved, in particular the conversion from VRayMaterial to the Corona Physical material (especially for metals and materials with colored reflections), and this change also influences imports from Chaos Cosmos. In Cinema 4D, the Scene Converter has also been improved to convert between Corona and C4D bitmaps, and now supports conversion of V-Ray lights.
The Corona Material library is now also available on Chaos Cosmos which can save you time when switching between the two asset libraries.

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 Group, allowing for further expansion and growth. Despite its young age, Corona Renderer has become a production-ready renderer capable of creating high–quality results. Boost your 3ds Max and Cinema 4D render workflows with more tools and features than ever before, including Chaos Cosmos and Scatter, plus Corona Decal and Slicer. Chaos Corona 12 is here Chaos Czech a.s. is part of Chaos Group, and specializes in developing easy to use, powerful and affordable software for 3D computer graphics and visual effects. Our technology helps artists and designers create photoreal imagery and animation for design, television, and feature films.
