note
All settings in this dialog are saved per-system rather than per-scene. This means that any scene opened on this computer will use these settings and if a scene is saved and opened on another computer, it will use the system settings specific to that other computer. These settings do not affect scene appearance or rendering performance. They are mostly useful for customizing Corona, for example: how often to autosave the rendered image, what name to use in the VFB title, what language the tooltips should be using, etc.
The system settings are stored in a file SystemSettings-<number>.ini in the folder C:\Users\_username_\AppData\Local\Autodesk\3dsMax\20XX - 64bit\ENU\en-US\plugcfg\corona
System Settings
Lock 3ds Max during render – When enabled, the entire GUI of 3ds Max is locked during rendering, except the VFB and render progress dialog. This is the default behavior in other renderers that can occasionally prevent crashes caused by modifying the scene while rendering.
Enable devel/debug mode– Enabling this checkbox shows a new rollout in the Performance tab with truly experimental, unfinished, and debug features. Use at your own risk!
# of threads (0 = unlim.)– Number of cores to use for rendering. Positive values work in a straightforward way, a value of 0 uses all system cores, a value of -1 uses all cores but 1, a value of -2 uses all but 2, etc.
Interactive Rendering
# of threads override– Number of cores to use for interactive rendering. Positive values work in a straightforward way, a value of 0 uses all system cores, a value of -1 uses all cores but 1, a value of -2 uses all but 2, etc.
IR Subsampling– Values higher than 0 make the interactive mode render in lower resolution for first few passes. This makes it faster and more responsive, but also "pixelated" for few seconds, until more passes are added.
Image upscaling factor– Specifies upscaling factor for the image rendered during interactive rendering. By increasing this value, render resolution gets reduced which makes the interactive rendering more responsive. This might be useful for High-DPI displays.
Enable material editor– Enables rendering of material editor shaderballs during interactive rendering.
Dissolve with previous image– When enabled, the newly rendered image gradually dissolves with the old image. When disabled, the new rendered image appears only after it has completely replaced the old image (i.e. after one pass).
Output Autosave
Enable autosave– When checked, automatic saving of rendering output is enabled. Useful for comparisons, and for backups in case 3ds Max crashes.
Autosave interval– The interval with which the render output is autosaved during rendering. The value is in minutes.
Number of images kept
On render end– Number of most recent (auto)saved image files kept on the hard drive. After reaching this number of files, older images start to get replaced with newer ones. This value applies to the final number of images after the rendering has finished. During render– Number of most recent (auto)saved image files kept on the hard drive. After reaching this number of files, older images start to get replaced with newer ones. This value applies to the number of images which are being kept during rendering.
Filename– Path and file name for the autosave file.
"Open" button– Opens the folder specified under Filename in Windows Explorer. "?" button– Shows a list of variables that can be used in the autosave file name to include various statistics and information (for example: current noise level, total elapsed time, number of rendered passes, current date and time):

VFB Settings
Type – Sets the frame buffer type used for rendering.
Corona VFB 2.0-Uses Corona's own customized frame buffer with extra functionality (recommended). Corona VFB - Corona's old customized frame buffer. Native 3ds Max VFB - Uses the default "Scanline" VFB. None - Does not display any VFB (the image still gets saved if file output is configured).
Update interval [ms] – The interval (in milliseconds) at which the VFB is periodically updated. Decreasing this value gives more fluid feedback at the expense of processing power that could otherwise be spent on the rendering itself. When the VFB refreshing takes too much of the rendering time, Corona adaptively lengthens this interval to up to 5 times of the set value to maintain adequate rendering speed.
Title– Window title of the Corona VFB.
"R" button– Resets the VFB title to defaults. "?" button– Shows a list of variables that can be used in the VFB title to include various statistics and information (for example: current noise level, total elapsed time, number of rendered passes, current date and time):

Render History and A/B Comparison
Automatic saving on render end– If enabled, a new item is added to the render history in the Corona VFB after each render ends. If disabled, items are only added manually via the button in the VFB.
Size on HDD (MB)– Maximum size in megabytes of the folder that holds the render history. If the size of all stored items exceeds this limit, then oldest renders get automatically removed.
Tooltips
Enable settings tooltips– Enables the render settings tooltips.
Language– Specifies the tooltips language.
Material Editor
Custom previews– When checked, previews in the material editor use Corona's own material editor preview scene. When unchecked, the native 3ds Max one is used.
Enable caching– When checked, renderings of materials inside the material editor are cached in order to speed up material editor.
Preview quality– Quality of the material editor previews. Higher quality provides less noisy previews, albeit in a longer time.
Def. roughness mode– Determines whether roughness or glossiness mode is used as a default one in the Corona Physical Material. Note that this setting only influences newly created materials.
Default IOR mode– Determines whether IOR (Index Of Refraction) or Disney Specular mode is used as a default one in the Corona Physical Material. Note that this setting only influences newly created materials.
Def. normals filtering–Choose the normals filtering mode for new Corona Physical and Corona Skin materials. "None" offers unfiltered, detailed textures, but can be noisy. "Linear" smooths textures but can lose detail at a distance. "Roughness mod." in Corona 11 maintains detail across distances and resolutions, balancing detail and render time. Applies only to new materials.
Out-of-core textures
Limit cache size – When enabled, you can limit how much HDD space is used by out-of-core textures by specifying the exact amount of taken space in GB.
Keep % of HDD free – When enabled, you can limit how much HDD space is used by out-of-core textures by specifying the percentage of total HDD space that must remain free.
Folder – Specified the folder in which to store the out-of-core textures.
Vantage Live Link
Address – Enter the IP and port to connect to Vantage. Default is localhost:20701
"R" button– Resets the Vantage Live Link address to default.
Product Usage Data
Settings – Opens the Chaos Telemetry settings window where you can enable telemetry.
Anonymized Telemetry – With Anonymized Telemetry, you share data on frequently used features and parameter values, which is not personally identifiable and is used mainly for aggregated statistics.
Personalized Telemetry – With Personalized Telemetry, you share the same data as with Anonymized Telemetry, along with information tied to your individual user license, which therefore contains personally identifiable information, and enables Chaos to further optimize the product for better personal use
Send Product usage data (takes effect after 3ds Max restart) – Controls whether sending of Product usage data is enabled. The change of this value does not affect currently running instances of 3ds Max, it takes effect when a new instance is started.
Save message preview to a file– Saves the Product usage data to a specified .txt file.
About– Shows a dialog with additional information about Product Usage Data:
