Chaos Corona delivers predictable, reliable, and physically plausible results with no compromise in quality. It offers both biased and unbiased rendering solutions, along with a 4K cache. Realistic lighting and materials are available right out of the box.

Render images in seconds with the new Corona to Vantage scene export. Import your Corona scene into Vantage to render still images and create Vantage animations, enjoying the lightning-fast speed of GPU rendering.

Use LightMix to adjust the intensity and color of your lights in the frame buffer, as well as create, save, and load multiple lighting scenarios from just one render.

Save time by eliminating the need for third-party software to perform post-production work on your renders, thanks to the wide range of post-processing tools available directly inside the Corona VFB.

Chaos Corona is great for animations as well as stills.

With resumable rendering, you can pause your renders in the Virtual Frame Buffer (VFB) and resume them later, enabling a highly flexible workflow.

Enable the Autosave function to save your rendering progress every few minutes in an .exr file. If your render or computer crashes, you'll have the latest progress safely saved.

Procedural Clouds let you control and type of cloud cover, and they are easy to animate. They respond to Sun color and position so work at dawn or at noon, and all with minimal effect on render times.

Tile real geometry over a surface with the same ease as you’d tile a texture, for the ultimate in realism all while saving memory. Use it to create fabrics, wire fences, jewelry, and much more.

Chaos Scans will give you access to hundreds of realistic materials that are too complex to simulate with regular materials.

Included in Premium are three powerful tools from Chaos. Phoenix will let you create realistic simulations of fire, smoke, water and more.

Now you can have control over the edges of your scatters, for keeping those lawns neat and tidy.

Control the amount of blur at the start, middle and end of the motion blur effect, replicating how it looks from a real camera.

For artistic purposes (since real world fisheye lenses do not show this effect), you can now add depth of field blurring to scenes rendered from fisheye cameras.

Chaos Player will give you the ability to edit and post-process your image sequences.

Corona Renderer uses a slightly biased solution, very close to being unbiased but considerably reducing render times. This is the recommended solution and works without you having to do any setup whatsoever. Corona Renderer will always deliver crisp, realistic results without splotches, interpolation artifacts or any other visual imperfections.

Fast Caustics Solver lets you easily add caustics to your scene. Once enabled, reflective caustics are calculated automatically for all materials in the scene. You can then enable refractive Caustics per material.

Corona Renderer merges the best of both worlds – the UHD cache is significantly faster than plain path tracing, but does not suffer from artifacts, missing contact shadows, or complicated UI controls.

Remove unwanted caustics with new Include/Exclude options.

Get the exact final look you want with new operators such as Tone Curve and Advanced Filmic Mapping, all in a user-configurable stack of operators so you can add, delete, and move them as necessary.

Generate industry-standard Cryptomattes, making it easy to isolate and adjust individual components in your render in post.

Our mission with Corona Renderer is to liberate users from technical and unnatural processes. We are constantly trying to simplify the creative process by removing or hiding any unnecessary technical settings, so that artists can focus on their vision. The era of studying manuals and tweaking sampling is over. Just press render and let Corona do its magic.

Corona Renderer is developed in tight cooperation with the artist community. Its creators are former artists as well, so this collective knowledge and experience plays a huge role in the design and on–going development.

Corona Renderer is compatible with a huge range of third-party plugins, so you can continue to use any tools you already have integrated into your workflow - whether you are using Corona's Interactive Rendering or doing a final render, you can keep right on using Q-GEOtexture, Q-TILE-PRO and many more.

Place trees, rocks, grass, flowers, cars in a parking lot, and other objects where randomization or repetition is required.

Instant access to a huge collection of assets, materials, and HDRI skies, right from within your 3D host application.

Corona Renderer aims to make you faster as well as your renders, with a workflow that is second–to–none. Thanks to its fully–featured Interactive Rendering, Corona Renderer brings you all the same advantages as a GPU render engine but without any of the drawbacks and limitations.

The denoising feature analyzes noise in the 3D space, so is not just a 2D post–process. You can use it to reduce the number of passes needed to get a noise–free image, with render time reductions of 50 to 70% reported to us by third parties in commercial usage (not in carefully crafted test scenes!). It will also remove fireflies (hot pixels) from an image, and can be used only in that mode if required. Corona Rendere use NVIDIA OptiX denoiser or Intel AI Denoising to achieve best results in no time.

All types of geometry and instances are supported, as are almost all Cinema4D native and 3rd party shaders, including the Cinema 4D shaders Beat, Bitmap, Brick, Checkerboard, Cloud, Color, Color(MoGraph), Colorizer, Cyclone, Display Color, Distorter, Earth, Falloff, Filter, Fire, Flame, Formula, Fresnel, Fusion, Galaxy, Gradient, Layer, Lens Distortion, Marble, Metal, Multi, Noise, Normal Direction, Pavement, Pixel, Planet, Polygon Hair, Posterizer, Projector, Proximal, Ripple, Rust, Simple Noise, Simple Turbolence, Spline, Starfield, Stars, Substance Shader, Sunburst, Thin Film, Tiles, Variation, Venus, Vertex Map, Water, Weathering, Wood. Full support of Cinema 4D native material layering and Cinema 4D native lights.

Corona handles scenes with many lights without problems and with no penalty to render time, so that you don’t have to worry about trying to optimize your scene.

This balances out the rendering calculations over the image to focus more processing power on tricky areas like shadows. By keeping noise more evenly distributed, this gives a usable image more quickly, and also allows Denoising to work its magic.

Use the Corona Slicer material to cut away sections of geometry at render time. You can cut with any shape that has the Slicer material applied, and even add caps to the exposed surfaces.

You can make any light source invisible to the camera, as well as invisible to reflections/refractions. Shadows can be turned on or off, and specific objects can be included/excluded from receiving illumination from any Corona light. Backplates can be easily created with the invisible to GI option.

The Rayswitcher material and texture allow a wide range of artistic tweaks when rendering with Corona. Use them to create materials invisible to camera, to create materials that don’t affect GI, to reduce or increase color bleeding, to have an object show differently when it is reflected vs. viewed directly, and more.

You can use different environment maps for reflections, refractions and direct visibility from the camera. For example, you can use a clear sky HDRI as a light source and a second cloudy HDRI just for reflections and refractions.

Corona implements its own shadow catcher (matte/shadow) solution. It is a single material with all the necessary controls in one place – there is no need to combine special materials with other special texmaps. It works especially well with our interactive rendering for rapid camera and illumination matching. Advanced features, such as light illuminators and matte bump mapping, are of course supported.

Using a Corona Camera, you can export images in Spherical or Cubemap format ready for viewing in a wide range of VR applications. While stereoscopic and panoramic images can be used in any VR software of your choice.

Corona Renderer was the first production render engine to implement the most accurate sky system available today – the Hošek-Wilkie sky. It is currently selected as the default whenever sun and sky is used, so adding those to your scene will get you instant realistic daylight.

There is no difference in behavior between a Corona Light object and a geometry object with the Corona Light Material applied – both of them have almost the same options and deliver the same results, so it is up to the artist to use what is more convenient!

There’s no need to set up an object to act as a dome light for HDR image–based rendering – just put your HDRI into the 3D software’s environment and you are done! There is also no need to put downsampled / blurred versions of the map into a GI override slot – HDRIs in Corona always work fast and without splotches, regardless of resolution or complexity.

With just a single click, you can set up the Interactive LightMix, a feature unique to Corona Renderer that lets you change the color and intensity of lights during or after rendering.

Ideal for automotive visualizations, product renders, and more, this mode “sticks” your 3D objects in place within the environment map as you move the camera around.

Our design goal for Corona materials is to make them physically based, yet intuitive, flexible, and easy to set up, without having to tweak unnecessary sampling values and other confusing parameters. You also won’t have to choose between 10 or 20 different material types, you can pretty much do it all using the single Corona Material.

Corona Renderer uses the GGX microfacet model to deliver realistic–looking metals and other glossy materials. Our implementation of the GGX model fully conforms to the industry standard physically–based rendering (PBR) workflow.

Full support of Cinema 4D native Hair Object and Cinema 4D native Hair Material in the Cinema 4D Hair Tag. Corona Hair Material can be used in addition to Cinema 4D Hair Material for realistic hair appearance.

Material previewing uses the same rendering engine as the final frame rendering. “What You See Is What You Get” representation in material editor.

Corona Renderer's 2.5D Displacement lets you achieve detailed and accurate displacement while still optimizing parsing times and memory usage.

Skin is one of the most complex materials to render, with many unique properties that cannot be covered in an all–purpose shader. The new Corona Skin Material makes it easy to control and adjust the look of the skin, and renders fast and efficiently with realistic results.

Corona Renderer’s implementation in the all–purpose Corona Material makes it simple. It doesn’t need any sampling controls, as all sampling is done automatically.

The Corona Volume Material offers an “Inside Volume” mode for true 3D volumetric materials. For example, by using a 3D noise map, you can have fog that varies in density in true 3D throughout the scene.

Cinema 4D lights and basic materials are rendered out–of–the–box using implicit conversion inside Corona without user interaction
also basic implicit support for V–Ray Advanced, Standard, Displacement and 2–Sided materials. Explicit user–initiated conversion, which converts the supported Cinema 4D materials, V–Ray lights and V–Ray materials to their Corona counterparts to allow further tweaking and changes in Corona.

You can’t have a great skin shader without also having a great hair shader! Corona Renderer’s dedicated hair shader keeps with our philosophy of delivering physical realistic results, fast rendering, and a simple UI.

Some refractive materials bend light by a different amount depending on the wavelength of the light. This is called dispersion and creates a rainbow effect in the refracted light. Dispersion can be enabled in the standard Corona Material, and is controlled by the single Abbe number parameter. Enabling it adds realism to gemstones, glass, liquids and other materials. Dispersion also works with Caustics.

For quick tests, or even for debugging a scene, it can be useful to override the materials with one simple material. This is easy to set up in Corona, with options that let you leave some materials (such as portals, glass, or light materials) unaffected by the override.

Easily add surface details or imperfections such as scratches, craters, cracks, smudges, splatters, and more, including displacement.

With this new parameter for the Corona Physical Material, you can create blurred reflections for metals to give a softer look with more “depth” to the material. It correctly affects caustics, too.

Add dirt or wear-and-tear derived from how quickly the surface is curving at that point.

The search process is automatic and Corona Renderer can even search for render nodes during rendering – render nodes will connect and disconnect automatically as you turn the computers on or off, without stopping the render!

When using Corona DR, you don’t have to give a second thought to where your assets are located – slaves will automatically gather models and textures before rendering.

Corona DR works with adaptivity, respect VFB render regions, while the UI keeps you informed of the status of all the slaves, how much memory they are using, and how many passes they have contributed to the current render.
