Build 2022.0916
New plug-in added for Cinema 4D 2023
Build 2022.05.25
If for some reason the environment variable had not been set for the location of main HDR Light Studio app, the fall back location was not being used, and HDR Light Studio wasn;t found by the connection. This is fixed now.
Build 2022.0414
Cinema 4D 26 support released, including Apple Silicon support
HDR Light Studio is now compatible with Cinema 4D 26. In addition, the Cinema 4D 26 plug-in is compatible with Cinema 4D running on Apple Silicon. This new plug-in requires the latest build of HDR Light Studio (2022.0426).
Please note: The HDR Light Studio main application is still an Intel MacOS app and runs via Rosetta on Apple Silicon computers. However, this does not stop it from performing very well and communicating with our new plug-ins compiled for Apple Silicon apps.

Cinema 4D R25 Connection Added
Build 2021.0519
The Cinema 4D connection now uses our new API for a far more responsive lighting experience. We also took the opportunity to rework the behavior of this connection, here are the key changes:
•Support added for Cinema 4D 24
•Moving lights is more interactive
•Simplified the Connection panel terminology to be easier to understand for new users
•You can switch Cinema 4D projects without HDR Light Studio closing and your lighting project will auto sync
•You can create multiple HDR Light Studio lighting projects in a single C4D project and correctly swap between them. This is also compatible with the Cinema 4D 'Takes' system
•Added support for V-Ray 5 (removed support for older V-Ray versions)
•Added support for real-time Area Light Spread control for: Arnold, V-Ray, Redshift and Octane
•Hiding the HDR Light Studio Connection panel on the UI does no longer stops the lighting updates. You can now tab the connection panel and have it behind another tab when using HDR Light Studio
•Logging has moved into the native Cinema 4D logging system
•On macOS, if the environment variable is not working to tell Cinema 4D the location of the HDR Light Studio application, the Connection will then look in the default install location. This fixes an issue where macOS users report Cinema 4D not able to start HDR Light Studio from Cinema 4D on macOS.
•Arnold: Fixed mapping of HDRI as Arnold had changed this orientation.
•Fixed a crash bug when opening pre Xenon Drop 3 'Octane' lighting projects containing HDR Light Studio area lights.
Please note we have officially stopped supporting Maxwell and Thea in Cinema 4D

Known Issues
LightPaint issue in the Cinema 4D Viewport
When using a low polygon model with a Phong Tag - light positions can appear wrong when Light Painting in the Cinema 4D viewport (or the Cinema 4D render in the HDR Light Studio interface). The reasoning for this is that the Phong tag interpolates across the polygon edges to "smooth" out the model, but this smoothing isn't taken into account in any of the maths functions we use to calculate the LightPaint positions. The workaround is to export the model into HDR Light Studio with the Phong tag on, and our Renderer will handle the "smoothed" surfaces fine with LightPainting inside HDR Light Studio.
