Chaos Corona feature list

Last update: April 13, 2022 | Version: Chaos Corona 8 | Plugin: 3ds Max

Render engine

  • Biased and Unbiased solution
  • Path Tracing: unbiased solution
  • UHD and 4K (experimental) cache: two options for faster biased cached solution for interiors
  • Denoising
    • Reduces the number of passes needed to get a noise-free image, with render time reductions of 50 to 70%
    • Easy to use and fast to render
    • Corona High Quality denoiser, best quality, recommended for final renders
    • NVIDIA AI GPU-based denoising can be used for final renders at the user’s discretion (requires a compatible NVIDIA GPU)
    • Intel AI denoising can be used for final renders. CPU-only, and works with any CPU (not just Intel)
    • Interactive amount adjustment
    • Checkbox to enable/disable the result in the VFB
  • Fast Caustics Solver:
    • Easy to use, and fast to render
    • Includes caustics from reflection, refraction, and dispersion (splitting light into separate colors)
    • Enable or disable for specific light sources
    • Works with LightMix
    • Separate render element available for compositing caustics in post processing for even greater control
    • Works correctly with motion blur
    • Include/Exclude list for control over which objects receive caustics
  • Adaptive Image Sampling
    • Balances out the rendering calculations over the image to focus more processing power on tricky areas
    • High Quality Image filtering, gives a more natural and “less CGI” look to noise, making it less noticeable to the eye
    • Progressive rendering
    • Max Sample Intensity (MSI): automatically removes fireflies - accuracy/render speed tradeoff
    • Proudly CPU based

Interactive lightmix

  • Adjust color and intensity of lights, during and after rendering
  • Single-click set up (by instances, groups or individual lights, with memory requirements reported)
  • Supports multiple suns and multiple environments for different times of day from one render (see Corona Sky and Corona Sun in the Lights section)
  • Manual set up if required
  • Controlled from the VFB
  • Results can be pushed to the scene
  • Can be used for anything from subtle adjustments, to turning day into night, without re-rendering
  • Each light select pass can be denoised independently (this can be enabled during automatic setup)
  • LightMix result can be saved to a CXR file and then adjusted in the Corona Image Editor, or saved for compositing in other post-processing software
  • Lights can be selected in the scene from the LightMix tab

Interactive rendering

  • 100% the same render engine as for the final frame
  • All final frame rendering features supported, including Interactive LightMix, post-production effects such as bloom & glare, LUTs, etc.
  • NVIDIA AI GPU-based denoising, for denoising during Interactive Rendering (requires a compatible NVIDIA GPU)
  • Pick objects directly in the docked viewport
  • Set DOF focus point directly in the docked viewport (for Corona Cameras)
  • Image upscaling factor to allow rendering to a smaller resolution and upscaling (ideal for HighDPI displays)
  • While zooming-in in the IR, rendering is focused on visible area only
  • Subsampling lowers initial resolution at the beginning of rendering, for virtually real-time performance
  • Blue Noise Dithering to give visually pleasing results in the first few passes, for quick assessment of a scene when using Interactive Rendering
  • Results shown in 3ds Max viewport or Corona VFB

Chaos Cosmos

  • Instant content for your scenes, including
    • Models
    • Materials
    • HDRI Skies

Chaos Scatter

  • Ideal for adding grass, trees, rocks, traffic or parked cars, crowds or pedestrians, etc. to your scenes
  • Can be used to scatter Decals
  • Control the distribution of hundreds, thousands, or millions of objects
  • Scatter on geometry, in a volume, or along splines
  • Distribute randomly, or in patterns
  • Limit distribution based on the steepness of a slope, e.g. prevent trees growing on cliffs etc.
  • Use spline include/excludes with controllable near and far parameters, e.g. to carve a path through trees, or limit flowers to a flowerbed
  • Associated texture map that colors scattered objects based on the colors of the object they are scattered on – ideal for created patterned rugs, variations in color on a lawn, etc.
  • Camera Clipping to limit scattering to within the camera field of view
  • Extend view parameter allows expanding the camera view culling to allow correct shadows or reflections from instances outside of the field of view
  • Edit or even delete individual instances after scattering
  • Random translation/rotation/scaling of instances, with optional discrete stepped values
  • Optionally avoids objects intersections, with tweakable inter–object spacing
  • Supports aligning instances to local normal
