Corona Rendering Core

Most render settings can be set using the Maxscript. You can list the settings usingshow renderers.current command. They are also listed here: Render Settings.

...

Statistic ID	Meaning
0	Number of elapsed passes
1	Number of primitives in the scene, not counting instances
2	Number of primitives in the scene with instancing
3	Average number of rays processed per second
4	Average number of rays processed for each image sample
5	Total render time in milliseconds
6	Total time spent in the rendering phase (in milliseconds). This time is used for deciding when to stop progressive rendering with a time limit set.
7	Estimated noise amount in the picture, in percents. Returns 0 if no estimate is available.
8	Estimated remaining rendering time (in milliseconds). Returns 0 if no estimate is available.
9	Memory currently allocated by Corona.
10	Peak memory allocated by Corona during the last rendering.
11	Virtual memory currently used by the process.
12	Peak virtual memory currently used by the process.
13	Virtual memory used by the system.
14	Scene parsing time in ms.
15	Displacement primitives.

Corona Proxy API

To invoke a method on proxy object [proxy], use CProxy.ProxyFp.[method_name] [proxy] [optional further args]

Function	Parameters	description
`getOriginalObjectName`	`<node>proxy`	Returns string containing the name of the original object from which the proxy was created.
`getOriginalMaterialName`	`<node>proxy`	Returns string containing the name of material of the original object from which the proxy was created.
`fromScene`	`<node>proxy <node>source <filename>filename`	Creates a proxy from scene object `source`, and saves it to file specified by `filename`
`fromSceneAnimated`	`<node>proxy <node>source <filename>filename <integer>frameFrom <integer>frameTo <integer>pointCloudSize <integer>samplesPerFrame`	Same as the other `fromScene`, but allows to specify additional parameters - animation range (`frameFrom` - `frameTo`), size of viewport display point cloud to precompute and store in the file, and number of motion blur samples to take
`duplicateToMesh`	`<node>proxy`	Creates a 3ds Max Editable Mesh from the proxy (does not delete the proxy). Same as clicking the Duplicate to mesh button in the UI.

Corona Material Library API

There are several published functions that can be invoked using the CoronaMaterialLibrary.MaterialLibraryFp interface. You can list them by executing showInterface CoronaMaterialLibrary.MaterialLibraryFp.

Function	Parameters	description
`isInstalled`		Returns TRUE if the library is currently installed. Returns FALSE otherwise (user de-selected it during Corona installation).
`showBrowserIfPossible`	`<boolean>show`	Displays or hides the browser window for the library, if possible. Returns 0 if it has succeeded, non-zero if it has failed.

Corona Scatter API

Valid until version 8 in which Corona Scatter has been replaced with more advanced Chaos Scatter with its own API.

...

Function	Parameters	description
`getVersionNumber`		Returns current plugin version encoded as a single comparable 64-bit integer version number. Version numbers returned in earlier builds are always lower than those returned in later builds.
`getVersionString`		Returns current plugin version formatted as a human-readable string. It is suitable to be presented to the user.

Example scripts

CoronaRenderer.CoronaFp.showvfb true

...

- converts my_proxy back to mesh.
