Corona Renderer 4 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 just some of the main features in Corona Renderer 4:
- Caustics: reflective, refractive, dispersion, can be enabled per light, fast to render, and easy to set up with no parameters required!
- Focus and object picker in the VFB
- Intel Denoising (AI denoising, on any CPU)
- Multiple suns and HDRI environments for use in LightMix
- Finalized New Light Solver, and new Image Filtering
- Fisheye mode for Corona Cameras
- The Corona Select map and material
- And more!

And here are the changes since the last daily build (for those who have been testing as releases come out):

- Changed the way CProxy visualization method interacts with the "keep in memory" checkbox - All the visualization methods are now always available and when the method is set to full mesh, the "keep in memory" checkbox is disabled because we need the proxy data in memory to display full mesh
- Fixed caustics solver causing fireflies when glossiness of reflection or refraction is lower than 1
- Fixed CoronaDistance map not working in displace modifier
- Environment overrides have been moved from environment dialog back to render settings.
- Added checkboxes enabling generation of caustics to Sun, Light, LightMtl and Environment (this one is located in the caustics rollout in the render settings)
- Fixed some some scenes rendering much slower when both adaptivity and high quality filtering were enabled at the same time
- Fixed high quality filtering sometimes producing NaNs (producing completely black VFB with bloom & glare enabled)
- High quality filtering is now auto-disabled in IR when the IR preview denoiser is enabled
- Added checkbox to VFB history tab for switching between using the current or the stored postprocessing settings
- Updated Intel AI denoiser to version 0.9.0
  - Up to 38% lower memory consumption
  - The denoiser now displays its progress and can be cancelled
  - Few bugfixes

Please post all bug reports, questions, etc. on the main version 4 Daily Builds thread at
