Changes in Corona Renderer 6 for Cinema 4D (Daily Build 2020-02-27) (https://drive.google.com/drive/folders/1Pq54oK-EGac_z0VdV05VfsSsG54I1Qkn):

Edit: Updated with changes and fixes that were included with the switch to the new Corona rendering core.

• Fixed:
• Fixed crash in IR, when rendering with soft selection
• Fixed rendering of projector shader
• Fixed occasional freezes when dragging connections in material node system
• Fixed blurring of caustics at the edge of the screen
• Fixed issue where light mix/postprocessing settings in VFB where not accepting values if mouse was outside of the VFB window
• Added:
• Introduced a new way to activate corona - you can set your email & password or a path to the licensing server to environment variable CORONA_ACTIVATION:
• For email and password, use format “email:password”
• For licensing server address, use format “LS:address”
• Added render stamp token %ptg which is replaced with the scene geometry preprocessing time (in milliseconds).
• Changed
• Temporarily removed Corona Standalone from the installer. We're currently doing a full rewrite of the Standalone code and it will be much faster if we don't need to maintain full backwards compatibility in every step during the development. The new version of standalone will be ready for v6 release.

Changes in Corona Renderer 6 for Cinema 4D (Daily Build 2020-05-06) (https://drive.google.com/drive/folders/1Pq54oK-EGac_z0VdV05VfsSsG54I1Qkn):

• Fixed:
• Fixed bug where object base material was being rendered transparently when another material was stacked over it with disabled tiling
• Fixed environment override not being applied to a fully visible Corona Sky
• Fixed bug where changing sky material visibility didn't affect the corresponding Corona Sky visibility
• Corona and C4D sun visibility is correctly handled now, both in IR and in non-IR

• IR now reacts to movement of a keyframed camera
• Fixed black viewport previews in S22
• Fixed problem with Ray Switcher material not showing in viewport
• Added:
• Added new adaptive environment light sampler based on the one in V-Ray
• Noise clears up to 2x faster in interior scenes in general; up to 9x faster in certain extreme cases.
• The new solver is now used as default for all new and old scenes.
• This solver removes the need for portals.
• Changed:
• Removed portal material, because it is no longer needed due to new adaptive environment light sampler

Changes in Corona Renderer 6 for Cinema 4D (Daily Build 2020-06-11) (https://drive.google.com/drive/folders/1Pq54oK-EGac_z0VdV05VfsSsG54I1Qkn):

• Added (randomized) tiling support to Uvw Randomizer shader
• You can specify how many tiles to make
• Optionally each tile can have a different randomization applied

• New secondary light solver: 4K cache
• Added new random sampler "Blue noise"
• It is the default sampler for new scenes
• Produces less visually distracting noise in low pass renders
• Examples: here and here
• Material dispersion Abbe number now support values lower than 10

Changes in Corona Renderer 6 for Cinema 4D (Daily Build 2020-06-30) (https://drive.google.com/drive/folders/1Pq54oK-EGac_z0VdV05VfsSsG54I1Qkn):

• Fixed:
• Fixed crash when using WireColor pass in Multipass

• Allow specification of seed in UVW randomizer in all modes when used for tiles randomization
• Reworked internals of material node system to improve stability and allow future improvements
• WARNING: the new node system saves data in a different format; if you use the node system in your scene and save with a daily build that's from Jun 30th onward, it will not load correctly in older daily builds from before that date!
• Stability improvements (fixes of crashes, materials rendering differently in viewport and VFB, parts of the node system not being updated etc)
• Materials with shared shaders should now correctly save and load in the content browser
• Partially fixed frequent nodes reordering when connecting/disconnecting nodes (some more improvements are yet to be done)
• Empty slot is now removed from the Layer shader when disconnecting shader
• Fixed problems/crashes when reconnecting shader from closed ports group into the same group once it was opened during mouse drag
• C4D Texture manager now displays all bitmaps used within the node system

Changes in Corona Renderer 6 for Cinema 4D (Release Candidate 1) (https://drive.google.com/drive/folders/1tP6AEkgQLZxosiAr6HUdJpflpwFLZm6n):

• Added:
• Added hue, gamma, temperature and green-magenta tint parameters to ColorCorrect shader
• Added support for %ptg token in render stamp
• Changed:
• UVW Randomizer now defaults to objects mode
• Fixed:
• Fixed problem with Corona plugin not loading on MacOS X Mojave
• Fixed typo in UVW Randomizer
• Distance shader now show simplified preview in viewport instead of error message
• Distance shader now doesn't render error message in cases where added objects don't contain any geometry
• Fixed inconsistency between IR and final render when there is an empty or invalid material tag on an object
• Changing "Use Cinema 4D color space" now correctly refreshes Corona VFB
• Fixed several crashes and hangs in IR when updating materials and shaders
• Fixed custom render stamp format not working in TR
• Fixed "Batch load textures" button on macOS that didn't allow a user to choose any file previously
• Corona Shared shader no longer appears in options in Node material editor (shaders sharing is fully handled by editor itself, so creating Shared shader doesn't make sense there and only caused problems)

This is our first release candidate, from now on we will be mainly focused on fixing bugs before releasing final version 6.
