Chaos Corona feature list

Last update: April 13, 2022 | Version: Chaos Corona 8 | Plugin: Cinema 4D

Render engine

  • Biased and Unbiased solution
  • Path Tracing: unbiased solution
  • UHD and 4K (experimental) cache: two options for faster biased cached solution for interiors

    • 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 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, and use the standard Cinema 4D transform widgets on them
  • 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 Corona VFB or docked viewport
