Corona Renderer 7 for 3ds Max (Release Candidate 1) is out now!

Everyone with an active FairSaaS or Box with Subscription license has access, and the download is in the usual location:

A Release Candidate is close to being the final release, but we need your feedback 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)
- Improvements to hybrid and thin glass (thin glass can now have rough refraction, better shadows, and more)
- Many 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)
  - Faster scene opening - by loading texture files in the background, scene opening times reduced by 35% on average, and up to 73% in some cases
  - Faster scene opening part 2 - by loading proxies in the background, scene opening times reduced by 12% on average (combines with previous scene opening speed up)
- Corona Sky in Improved Mode now includes Turbidity and Altitude
- And more!

And here are the changes since the last daily build (for those who have been testing as releases come out):
- Fixed crashes in some cases when bump map is evaluated to NaNs
- CoronaNormal - improved the tooltip for the "Add gamma to input" checkbox
- Corona Converter:
  - Made the error log more readable by adding additional indentation and newlines
  - VRayMtl is now converted to CoronaPhysicalMtl directly instead of using CoronaLegacyMtl as an intermediate step
  - Simplified the shading networks generated by the conversion
  - Added a better warning for when V-Ray is not installed

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 thread at
