Corona Renderer 2 for 3ds Max (Release Candidate 4) 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. The final release is getting very close now; we expect this to be the last RC, so do please test as much as possible.

Here are the changes in RC 4 since RC 3:

- LightMtl no longer allows negative intensity
- Right-click menu in include / exclude lists (e.g. CoronaLight) has been expanded with "Select objects in scene" and "Add objects to scene selection" options
- Fixed issue with rotated CoronaBitmap and environment mapping
- CoronaCamera, added Anisotropy factor to bokeh effects
- CoronaCamera, fixed automatic tilt not working correctly in animations
- Slightly reworked the Material Overrides UI

- CoronaVolumeGrid
  - Fixed rendering artifacts when the step size was too low
  - Fixed step size being incorrectly internally interpreted as specific in voxels instead of scene units
  - Absorption map now tints the volume color, instead of selecting which color will be absorbed (to be consistent with other absorption controls)
  - Cell counts in status window now contain thousands separators, and are shortened for large values for better readability
  - Fixed crash when rendering a CVolumeGrid with no grid files loaded
  - Fixed OpenVDB files not being sent to slaves when using Backburner
  - Emission / absorption / scattering Tint color is now disabled and not taken into account when a map is set
  - Stats box moved to a separate roll out
  - Fixed absorption to really repsesent what is basically a color tint of the volume
  - Fixed channels being reset to their autodetected values when reloading an OpenVDB file
  - Grid mapping dialog "reset" button now resets to defaults and not to the state before the dialog was opened

- Material Library
  - Renamed some of the new materials to have more descriptive names
  - Previews are now rendered in a bigger resolution (1024 x 1024)
  - The category "Foilage" has been reanmed to "Nature" to better describe the contents. Note that any Foilage materials previously set as Favorites will be rest due to this change

- CScatter
  - Fixed  bug causing different scattering (moved/missing instances in some  cases) on Intel CPUs vs. on AMD Threadripper/Ryzen CPUs. In rare cases  some instances may be scattered a bit differently.
  - Fixed the Scatter Lister to avoid Maxscript errors with the new Corona Scatter parameters
  - Improved tooltips.
