Chaos Corona 9 Hotfix 3 v9.3 for 3DS Max 2016-2024
Corona is the only render engine with a specific focus on the needs of the archviz community. While also capable and well-liked in the fields of automotive and product visualization, the UI, feature set, pricing, and ease of use are primarily driven by what architectural visualizers require.
While remaining unique with its own development team, code, and community, Corona now also benefits from being part of the Chaos ecosystem, giving its users access to many of the industry-standard tools created by Chaos.
MAJOR FEATURES
Procedural Clouds
The Corona Sky was great, but was always a clear sky. HDRIs can be great, but you’d need a unique HDRI for different levels of cloud cover or different times of day, and they were static (or if animated, needed a huge number of large files that took up a ton of space on your hard drive).
The new Procedural Clouds solve all these issues, letting you tweak the amount of cloud cover, the shape of the clouds, their position in the scene, and animate them with ease. You even get to add and animate airplane trails (contrails) across your sky!
Due to how they are calculated and rendered, they have minimal effect on render times compared to full volumetric solutions. They can even be previewed in the viewport, so you can adjust the settings without having to render or even use IR.
The Procedural Clouds respond to the position of the Sun, so you can have evening and dawn just as easily as you can have full noon. You can search for the look you like with the random Seed option, and all of the parameters can be animated so that clouds can move, cloud coverage can grow or reduce, and so on. You can also choose whether the clouds cast shadows into your scene or not.
Corona Pattern
Now you can tile real geometry over a surface, with the same ease as you’d tile a texture. Not only does this give you far more realism than you’d ever obtain with opacity, bump, and displacement maps, it also requires far less memory than those alternatives.
To get a quick grasp of when this is useful, think of things such as:
Fabrics, where those are made of knitted or woven strands
Wire fences, fireguards
Jewelry such as chains
And much more!
To simplify working with Corona Pattern, you can have the height of the geometry scale automatically and naturally with the tiling so that the height reduces as the geometry is scaled more frequently, or you can choose to disable this and set a manual height if required.
Of course once you get to grips with the tool, you’ll start to think of many other ways in which it can be used, raising the realism of your scenes to a whole new level. Meantime, we have a few examples of geometry that you can use with Pattern, you can download them here.
Edge Trimming
This has been the single most requested feature for Chaos Scatter. We’re happy to let you know that it is now included in this latest update to Scatter. A prime example is letting you control the edges of lawns and other grass areas, as seen below:
The effect relies on the way the geometry being scattered is set up. If you are scattering individual grass blades (unlikely, as this would be very inefficient!) then you will already have good edging. The Edge Trimming will help when you are scattering “clumps” of individual grass blades, by hiding the individual blades which would be out of bounds.
To set it up, you simply add a Scatter Edge Trimming shader (Cinema 4D) / ChaosScatterEdgeTrimming map (3ds Max) into the opacity slot of all materials being used on the objects being scattered. This methodology and result is similar to that used by other scattering tools for Corona 9, but in the future we want to simplify the process, e.g. by using a single checkbox.
Out of Core Rendering for Textures
This option reduces the amount of memory required for texture maps loaded via Corona Bitmap. Testing done in-house and by a few archviz studios have seen savings of between 5 and 70%, depending on how heavy the scene is, how big the textures in use are, and other factors.
This is disabled by default in Corona 9, and you will have to activate it to take advantage of it. This is done via a checkbox in the Performance section of the Render Settings:
Corona will automatically allocate the space needed on the hard drives when the option is enabled. Manually overriding the settings is also possible if desired, under the System settings. When using OOC Textures, Corona will automatically clear the cache on loading a new scene or on closing the host application.
The Out of Core texture rendering makes a difference when the texture has a higher resolution than what is needed based on its placement in the scene.
Shutter Curve for Motion Blur
In the real world, a camera’s shutter will take a certain amount of time to open, and a certain amount of time to close, and there are usually some elements of acceleration and deceleration involved in both those processes.
The Shutter Curve controls for Motion Blur will let you accurately represent these effects in your renders. Rather than an even, linear result, you can achieve less or more blur at the start, middle, and end of the blurred area. This is a case where “examples are worth more than words”
Hardware Requirements:
Corona requires a CPU that supports the SSE 4.1 instruction set.
Only very old CPUs don't support it: Here is a list of compatible CPUs.
To use our optional Fast Preview Denoiser (NVIDIA OptiX), you need an NVIDIA GPU with Maxwell or newer architecture and the newest GPU driver. Not all mobile GPUs are supported.
Note: this denoiser type is optional, and Corona works fine even if it's not installed (for example if you are using an AMD or integrated GPU). We also offer a High Quality denoiser, which utilizes purely the CPU, and this denoiser can be used on any computer which can run Corona.
Software Requirements:
3dsMax version
Autodesk 3ds Max version 2016 or newer
64-bit Microsoft Windows 8 or newer
