NOTE: This version installs new data used by PRG sky model that is currently incompatible with previous versions of Corona. This data is automatically upgraded/downgraded when running installer, however you might have problems if you use multiple versions of Corona at the same time (for example when keeping older Corona versions installed in separate installation of Cinema 4D). We are working on removing this limitation in the future daily builds.

Changes in Corona 12 for Cinema 4D (Daily Build) (https://drive.google.com/drive/folders/1kZij6EEuQ1y-raj9m83P_6sRQ3TSUXCM):

• Added:
• Added option to enable edge trimming for the whole Chaos Scatter (i.e. without modifying individual materials used on scattered objects)
• Added spline UI for additional control of Look At in Chaos Scatter
• Added option to select connected nodes (incoming and/or outgoing) for nodes in material node editor
• incoming nodes can be also selected by Alt + left click
• When new material/shader is added in material node editor, all newly added nodes are selected

• Added accurate sampling mode for environment maps that is slower but delivers more accurate results, especially for large environment maps
• Added option to distinguish media based on their material (e.g. two intersecting objects with the same material will be now considered as a single volume)
• this is automatically active for new scenes
• Fixed:
• Fixed several issues in Chaos Scatter where instances would not generate for a long time
• This should hopefully resolve some of the reported issues where the scene would not load for extreme amount of time, please let us know if you can still reproduce it.
• Fixed issue where changing tone mapping after rendering finishes would reset color profile of image in Picture viewer
• Improved detection of low memory on macOS (showing RAM usage warning)
• Reduced UI freezing when using distribution shader in Chaos Scatter distributing over high amount of triangles
• Fixed maximum value for randomization options in Tile shader
• Changed:
• Legacy options in Development/Experimental section in render settings were organized into single section

Changes in Corona 12 for Cinema 4D (Daily Build) (https://drive.google.com/drive/folders/1kZij6EEuQ1y-raj9m83P_6sRQ3TSUXCM):

• Added:
• Added support for conversion of V-Ray lights in scene converter
• Fixed:
• Improvements of handling of assets from asset browser and performance fixes when non-asset browser paths could cause slowdown in some setups
• This reduces slowdown in some cases with custom asset databases connected. We hope this resolves reported slowdown when loading scenes, however we were not able to fully reproduce the reported issues. Please let us know if you can still reproduce some loading time issues with this build.
• Fixed problem with "Save selected objects as..." resetting materials and not saving connected submaterials in C4D 2024
• Changed:
• Flattened plugins submenu when creating shader in Corona node material editor

Changes in Corona 12 for Cinema 4D (Daily Build) (https://drive.google.com/drive/folders/1kZij6EEuQ1y-raj9m83P_6sRQ3TSUXCM):

• Added:
• Initial support for exporting scene into Chaos Vantage
• New scene exporter for Corona scenes into .vrscene/.vantage that can be rendered in Chaos Vantage

• Note that not all features are supported, we'll continue improving the quality of exported scene both in following builds and future major releases
• Initial prototype for new version of Corona VFB
• Option to switch to new VFB 2 is available in Corona preferences, C4D must be restarted before the change to different VFB version has an effect
• Added possibility to compare different resolution renders
• Added possibility for loading of Corona EXRs and editing them directly in VFB
• There are some known issues regarding DPI scaling other than 100%, most of these reproducible on macOS, we are working on improving these for the next build
• Added new tonemapping operator for Lift, Gamma and Gain
• Added the option to apply the LUT in linear color space instead of gamma-mapped one
• Added option to use automatic caps in Corona Pattern modifier
• Pattern visibility in Corona Pattern modifier can now be controlled with shader
• Added visual indication of pattern direction for Corona Pattern modifier
• Added option to fit Corona Pattern cropbox using space of another object
• Fixed:
• Avoid node stacking in node editor UI when adding multiple bitmaps via drag&drop
• Fixed issue with texture paths in XREF objects not correctly resolving
• Fixed several issues regarding crop/placement set in pixel space (e.g. when changing bitmap path to one with different resolution)
• Fixed incorrect custom gamma when exporting C4D bitmap to Standalone
• Fixed Cryptomatte accumulation from EXR (affect TeamRender and resume render)
• Fixed incorrectly handled animation tracks for some spline widgets used in Corona/Scatter (e.g. Scatter altitude, Corona Color Correct shader)
• Changed:
• Removed "Ignore missing tiles" option in Corona Bitmap as it was only used for error reporting; instead, number of loaded tiles is now directly included in the image description

This is our first RC, we'll now focus on testing and resolving remaining issues.

• Chaos Vantage export improvements:
• Added support for decals
• Added very basic support for C4D noise shader
• Added limited support for MapRandomizer and MultiShader
• Added support for Sphere light
• Sphere, rectangle and disk lights (without texture) are now listed in Vantage Lights tab and render in Vantage much faster
• Support for camera near/far clipping, DOF, tilt&shift and resolution/aspect ratio
• Improvements in new version of VFB:
• VFB 2 is now enabled by default
• Added support for multiple LightMix configuration in single render (each tied to single LightMix pass)
• Fixed IR resizing of render based on VFB size and added support for IR size locking
• Polishing of UI design
• Several fixes related to DPI scaling
• Fixed issue where displayed statistics in VFB2 were inaccurate (actual ray/s, sample/s) or missing (max passes, noise limit)
• Added
• Added solo nodes in node material editor
• In this version the material with active solo node renders with that node used for diffuse
• In next version we plan to switch the behavior to use self-illumination instead, similar to how this feature works in other renderers
• Lister now shows instance count also for Chaos Scatter and Cinema 4D Cloner and Array
• Fixed and changes:
• Corona and Scatter shader menus are now copied (instead of being moved) to top-level shader menu in node material editor
• Warning is shown when old sky data is installed on the system and Sun elevation is set below 4.2 degree
• Fixed issue with Pattern modifier handles showing size clamped to zero when dragging handles in negative axis direction
• Added warning about deprecating Corona Material Library and moving it to Cosmos
