Corona Renderer 7 for Cinema 4D (Release Candidate 5) is out now!

Everyone with an active FairSaaS or Box with Subscription license has access, and you can download it from:

We're getting ever-closer to the final release, so this is an important chance to give us your feedback and to catch any remaining bugs or other issues from real world testing.

Here are some of the bigger features in Corona Renderer 7:
  - New Physical Material - greater realism without extra work from you, and greater compatibility with other software and workflows (mapped Metalness, choice of Roughness or Glossiness mode, choice of IOR or Specular mode, and more)
  - Corona Sky with the PRG Clear Sky model (renamed from Improved) now has Volume Effect (aerial perspective), Altitude, Turbidity, and Horizon Blur
  - The Corona Material Library - hundreds of ready made materials for use in your scenes
  - Corona Volume Grid - load and render OpenVDBs using Corona
  - Improvements to hybrid and thin glass (thin glass can now have rough refraction, better shadows, and more)
  - Several rendering speed ups that add up:
  - Bucket Rendering, a 5% overall speed up on average, up to 15% in some cases (note: not like V-Ray bucket rendering, you will still see the whole image build progressively!)
  - Faster Denoising in our own High Quality denoiser, a 20% speed up on average, up to 60% in some extreme cases
  - Faster Transparency / Absorption, will depend how heavily these are used in the scene - can be up to 50% in extreme cases (note, does not affect Translucency)

There have been a great many changes since the first RC. Here are the JUST changes since Release Candidate 4 (for those who have been testing as releases come out):

 - 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 matetrial 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

Please test as much as possible and report your findings to us, so that we can make Corona Renderer 7 ready for release as quickly as we can!
Please post all bug reports, questions, etc. on the main Corona 7 Daily Builds sub-forum at
