    • Fixed problem when re-exporting Corona proxy over already loaded proxy file would result in incorrect material information shown in proxy parameters
    • Fixed problem with material not updating in IR when it is changed directly from render settings dialog
    • Fixed issue where NaNs could appear when using black environment override or disabling "Visible in reflections" inside Corona Sky
    • Fixed problem with Lightmix layers called R, G or B not being recognized as lightmix layer after export to Corona Image Editor

Changes in Corona Renderer 8 for Cinema 4D (Daily Build 2021-12-20) (

  • Added
    • Added Slicer material
    • Dome mapping can now also be used in environment overrides in render settings
    • Decal object can now fully replace bump mapping of original object
  • Fixed
    • Updated help page shown in Corona -> Help dialog

    • Min level and water level are now correctly grayed out for vector displacement

Changes in Corona Renderer 8 for Cinema 4D (Daily Build 2021-12-03) (

  • Added
    • Added Corona Decal
      • projects a selected texture/material on any geometry
      • works even when layering multiple materials on single decal
      • can be used with instances and multi-instances
  • Fixed
    • Improved performance when reading HDR images in Corona Bitmap
    • Improved performance in IR in some scenes where IR was slower than normal rendering

Changes in Corona Renderer 8 for Cinema 4D (Daily Build 2021-11-10) (

  • Added native support for Apple M1 processors
    • supported for Cinema 4D S24 and R25
    • provided installer installs universal version of Corona that can run both on Intel and M1 devices
    • based on our tests, running native version results in 45-50% faster rendering compared to running under Rosetta
    • in case Cinema 4D was previously set to run under Rosetta with previous versions of Corona, don't forget to disable Rosetta in Cinema 4D application properties
  • Added blend and additive displacement handling into Layered material

Changes in Corona Renderer 8 for Cinema 4D (Daily Build 2021-10-29) (

  • Added:

    • Added OIDN feature pre-denoising (OIDN 1.4.0 new feature)
    • Added partial support for vrmesh proxy files
      • Please note that the current implementation of our vrmesh loader is limited in a way that it can load only proxies containing a single mesh. This will be extended with full support later
  • Fixed:
    • Fixed bug when rendering gets extremely slow and memory consumption gets very high in some special cases by adding limit to the number of splits per path
    • Fixed dark spots when lights are invisible to reflection
    • Fixed occasional crash when rendering shader previews in Corona node material editor
    • [REGRESSION] Fixed light leaks in UHD and 4K caches

Changes in Corona Renderer 8 for Cinema 4D (Daily Build 2021-08-16) (

  • Fixed:
    • Fixed conflict with some other renderers caused by usage of the same dependency libraries
    • Fixed problem with Corona Bitmap not working with absolute paths in R14
    • Fixed problem with material library download occasionally not starting when installing on macOS

Note: all changes in this build will be released in a v7 hotfix, so this is more of a hotfix preview than actual v8 daily build.

Changes in Corona Renderer 7 for Cinema 4D (Final Release) (

  • Changed:
    • Level in ColorMix shader is no longer limited to 100%
    • Corona Bitmap now allows additional UVW scaling
    • Scene conversion dialog now allows conversion of all Legacy materials in the scene
  • Fixed:
    • Fixed occasional crash when closing Cinema 4D
    • Fixed renaming of Corona assets (Corona Bitmap, Corona Proxy) in Cinema 4D Asset inspector
    • Fixed reverse order of materials in material library when sorting by overall usage
    • Fixed warning regarding Corona VFB color space being incorrectly shown for first start of Cinema 4D
    • Fixed problem with "-h" and "--help" arguments not working with Corona installer

Changes in Corona Renderer 7 for Cinema 4D (Release Candidate 5) (

  • Fixed:
    • Fixed crash when closing Cinema 4D
    • Fixed problem with caustics from environment not rendering in IR
    • Improved imports of ColorMix shader in material library for several materials
    • Removed unsupported "Hair Textured" material from Material library
    • UHD cache stored in older versions is no longer supported - such legacy UHD cache files will be calculated/updated from scratch; this fixes several problems including crashes when loading such legacy cache files
    • Crop / Placement values inside Corona Bitmap now increment correctly for UV Unit space

Changes in Corona Renderer 7 for Cinema 4D (Release Candidate 4) (

  • Changed:
    • New sky model is now called PRG Clear Sky
  • Fixed:
    • Fixed problem with some materials from material library having incorrectly enabled SSS
    • Updated tooltips to correctly reference percentage instead of 0-1 values
    • Fixed bug with objects with displacement not correctly updating in IR when changing geometry
    • Fixed problem with Volume Grid not rendering with Team Render
    • Fixed resolution of relative paths going outside project folder in Corona Bitmap and Corona Proxy
    • Export of objects into proxy now also creates separate material channels for each different mapping of the same material

Changes in Corona Renderer 7 for Cinema 4D (Release Candidate 3) (

  • Material library:
    • Added 13 new metal materials
    • Added 13 new masonry materials
    • Added 9 new wood materials
      • All new materials are built upon the new physical material
    • Converted existing carpets, ceramic tiles, concrete and flooring materials to the new physical material
      • Note that this might result in a slightly different visual result, however existing scenes based on the previous versions of material library will be unaffected
    • On Mac, Material Library download and installation is now included in Corona for Cinema 4D installer
  • Changed:
    • Bucket rendering disabled for IR, because in some cases it is still too visually distracting
      • Buckets are still enabled in production rendering after 5 passes (and in Team Render from the render start) for better performance. We'll experiment with IR buckets more in v8 to get some better solution.
    • Reintroduced fake horizon blur for the new sky model
      • Default horizon blur is now 0 since the blurring should be controlled by the physically correct altitude parameter
      • As horizon blur wasn't working in previous versions, scenes created in RC1 and RC2 might render slightly differently if it is set to non-zero value
  • Fixed:
    • Increased altitude range of new sky model up to 15000 meters
    • Fixed problem with material converted from Legacy to Physical having base layer mix strength set to 0%
    • Fixed new sky model being black below horizon in orthographic cameras
    • Fixed problem with objects with displacement dissapearing in IR
    • Fixed green/magenta tint in the new improved sky model volumetric effect when computed for short distances (under 200 meters)

      • Note that this will unfortunately change a look of scenes created in the recent daily builds
    • Open Image Denoise (Intel AI denoiser) updated to version 1.4.1 - this fixed some crashes when denoising certain resolutions
  • Fixed:
    • Fixed bug with material library previews not updating correctly when size slider is changed using keyboard or mouse wheel
    • Selected category in material library is now preserved when changing filter text
