Chaos Corona 12, update 1 released for both 3ds Max & Cinema 4D
Corona 12, update 1 introduces powerful new features to get you render-ready faster than ever. Unlock new levels of speed and collaboration, deliver immersive client experiences, and achieve stunning photorealism with greater ease.
Full details and download: chaos.com/blog/corona-12-update-1

What's new in Corona 12, update 1:
  • Corona to Vantage Live Link. Take advantage of Vantage Live Link as an alternative to Interactive Rendering.
  • Chaos Cloud Collaboration. Easily share images with your clients, sending them right from the VFB, then discuss changes via markup, send deliverables, set up Virtual Tours, and open the door to much more in the future.
  • Faster Caustics. Caustics now look around twice as good in the same rendering time.
  • Caustics Multiplier. Enjoy a quick and easy way to adjust how bright caustics are in your final render, controlling on surfaces and in volumes separately.
  • Volumetric Caustics. See reflected and refracted rays generated by caustics as they pass through volume materials.
  • Auto Exposure and White Balance. Have your exposure or white balance auto-adjust for a good starting point, or adapt to changing lighting during animations. White Balance has also been improved with a new algorithm for more pleasing results.
  • Image Upscaling. Speed up creating test renders by around four times, and add extra responsiveness to IR.
  • And much more!

Chaos Corona 12 for 3ds Max (Hotfix 1)
This release brings the following improvements and bug fixes:

Improvements
  • Disabled history autosaving for sequences and for render nodes during distributed rendering. This is to avoid popping up a blocking confirmation dialog about history item deletion when the user is likely not around.
  • Added bakeIthLightMix function to MAXScript to allow baking parameters of a specific light mix element.
VFB 2
  • Fixed issue where several of the new parameters (Bloom&Glare compute after rendering, IR resolution lock, VFB history settings) could not be accessed via maxscript.
  • Fixed issue where interactive rendering would disable denoising blending in VFB2 for the following production rendering.
  • Fixed errors when switching color management mode while IR is running.
  • Fixed crash when using "scene-linear Rec.709-sRGB" space in OCIO mode, when the scene contains dispersion.
  • Fixed pick and region mode turning off after IR is started.
  • Improved rendering speed of the Corona Tile Map on high core count machines.
  • Fixed crash in Corona Pattern occurring when using a pattern object with degenerate triangles.
  • Fixed issue where changing aperture parameters did not refresh VFB2.
  • Fixed rare crash while switching from zoomed-in production rendering to interactive rendering.
  • Light select names in VFB2 now update after renaming and re-rendering, also when editing a specific CXR loaded into the VFB.
  • Fixed issue where VFB2 could crash when deleting a history item without using VFB2 controls.
  • Fixed issue where light mix was reset when docked IR was started.
  • Fixed dialog resizing on render start to adjust its size to contain as much of the rendered image as possible.
  • Fixed locked IR resolution second dimension value being wrong on entering (due to upscaling factor).
  • Fixed issue where VFB2 was not updated when render stamp was changed from MaxScript.
  • Fixed issue in Corona Image Editor where tone mapping in rare cases could look different than tone mapping in Corona VFB.
  • Improved frames per second in docked VFB.
  • Fixed issue where NVidia denoiser was not applied during production rendering. Added missing refresh of VFB when denoising is done.
  • Fixed issue where IR was restarted while VFB dialog size was changed even though its resolution should have remained unchanged.
  • Fixed copying of colors between different color swatches in Lightmix tab.
  • Fixed issue where 3ds Max would freeze when history item deletion dialog is shown after rendering finishes.
  • Fixed saving of CXRs for light mix elements.
  • Fixed bad_optional_access error when opening Render setup dialog during rendering.
  • Light mix layers can now be toggled by clicking on their names, not just the checkbox, same as in the old VFB.
  • GammaCorrectionOperator present in .conf files is now handled correctly - the operator is removed from the pipeline and the rest is loaded correctly.
  • Fixed issue where real-world mapping was not applied on some materials imported from Cosmos.
  • "Show VFB" now also raises the VFB2 above other 3dsMax's dialogs (as VFB1 did).
  • Fixed IR restarting/changing appearance after Render Setup dialog is open.
  • Fixed issue where VFB would show when updating a scene with docked IR running.
  • Fixed color management update when loading a Corona scene with another renderer being set as default.
  • Fixed issue where old V-ray materials could not be rendered/converted.
  • Fixed incorrect position/scale of VFB2 after restore from previous session on multi dpi monitor setups
  • Fixed issue where scatter edge trimming would in some cases incorrectly trim instances.
  • Fixed issue where minimized VFB stays hidden when rendering starts.
  • Fix of not updating VFB2 when option "Lock 3ds Max during render" is enabled.

Chaos Corona 12 for Cinema 4D (Hotfix 1)
This release brings the following bug fixes and improvements:

VFB 2
  • Fixed issue where IR was still running when VFB2 was closed.
  • Fixed setting of focus when VFB2 is first activated.
  • Fixed dialog resizing on render start to adjust its size to contain as much of the rendered image as possible.
  • Fixed issue where interactive rendering would disable denoising blending in VFB2 for the following production rendering.
  • Fixed pick and region mode turning off after IR is started.
  • Fixed crash in Corona Pattern occurring when using a pattern object with degenerate triangles.
  • Fixed issue where changing aperture parameters did not refresh VFB2.
