Corona Renderer 2021
Demo of March 26th daily build, showing how Corona Renderer 2 can render a V-Ray scene without conversion (works even without V-Ray installed, too). Public Render Farm License. Access to all versions, individual conditions; Cost: 10-15% revenue from all jobs rendered using Corona Renderer (the minimum fee is 100 €/month) Unlimited Render Nodes; If you are a commercial render farm owner, or if you run a cloud render farm service, you can get licenses for all your machines without the initial investment. How to install CORONA 2. 3ds Max Corona Renderer 6. Released on Aug 31 st 2020 (hotfix on Sep 29 th 2020); Works with 3ds Max 2014-2021 note; Download Corona Renderer 6 for 3ds Max (hotfix 1) Older versions.
Most render settings can be set using the Maxscript. You can list the settings using show renderers.current command. They are also listed here: https://corona-renderer.com/doc/
There are several published functions that can be called using the CoronaRenderer.CoronaFp interface. You can list them by executing showInterface CoronaRenderer.CoronaFp command. Most functions return an integer, that is zero on success, and nonzero on failure.
Adding new functions is very easy, so contact us if you need any.
Function Parameters description 
showVfbshow Displays or hides the VFB window. When the argument is true, calling it is the same as clicking 'Show VFB' button in the UI. 
resumeRender Resumes the last rendering. Same as clicking 'Resume last' button in the Actions tab. 
loadAndResumefilename Same as resumeRender, but loads the last render from a given previously dumped EXR file. 
dumpVfbfilename Saves the current VFB contents to given file so it can be resumed later using loadAndResume. 
setDisplayedChannelchannel If using Corona VFB, it sets the currently displayed channel. 0 is beauty channel, 1 is alpha, and higher values are extra render passes. 
getVfbContentchannel toneMapping renderStamp Returns bitmap with one render channel from the current framebuffer. Optionally can include tone mapping and renderstamp. Does not return integer code, but directly the bitmap (or null if the call failed). 
resetSettings Resets the render settings to default values. Same as clicking 'Reset Settings' button in Actions tab. 
renderElementsuseAntialiasing[DEPRECATED] Renders only the extra render elements, without main shading (so it is much faster). Some elements depend on the shading and will not show when using this option. Has a parameter to enable/disable antialiasing. Same as clicking 'Render only elements', or 'Render only elements (without AA) in the Actions tab. Removed in version 1.5 and replaced with regular render with Render only elements checkbox enabled. 
exportScenefilename renderImmediatelyExports the scene to given file so it can be loaded in the Corona standalone application. If renderImmediately is true, then the application will also look for the standalone executable and try to run it immediately. 
getCoronaVersion[DEPRECATED] Returns current Corona version formatted as a human-readable string. It is still available but will be removed in future versions in favor of getVersionString providing the same string. 
getStatisticstatisticId Returns one of the statistics from the table below, in double precision floating point format. Returns results from the currently active render or last render. If no render occured yet in the session, or 3dsmax was reset/renderer changed after the last render, then the results are undefined. 
getBlackbodyColortemperature Returns the color of a black body emitter with specified temperature (given in Kelvins). The returned value is in HDR linear sRGB color space (without gamma correction). The result is normalized - the brightest color channel is always equal to 1, and the absolute brightness of the color does not correspond to the reality (only ratio between different color channels is meaningful). Input color must be in range 1000-99000K 
loadDrIpFilefilename Loads a text file containing 1 IP per line into the DR nodes list. Same as clicking on the button 'From file…' in UI and selecting the provided file. 
startInteractive Starts the interactive rendering in Corona pop-out WX VFB. 
startInteractiveDocked Starts the interactive rendering in the Corona viewport-docked VFB. The viewport (extended view) needs to be present and inactive for this method to work 
stopRender Stops any render that is currently going on 
isRenderingReturns true if Corona is currently rendering. Added in version 1.5 Removed in version 1.6, replaced with getRenderType
reparseInteractive While in interactive rendering session, reparses the entire scene and restarts interactive rendering. Added in version 1.5 
getRenderType  Returns 0 if there is currently no render going on, 1 for offline (non-interactive rendering), 2 for interactive rendering with docked VFB, and 3 for interactive rendering in regular Corona VFB. Added in version 1.6. 
saveAllElementsfilename Saves all render elements to specified location - same as when using the Corona VFB button functionality. The provided parameter is the filename of beauty channel, other filenames are derived from it. 
showLightMixSetupDialog Shows the LightMix setup dialog, if not currently rendering. Added in version 2. 
getVersionNumber Returns current Corona version encoded as a single comparable 64-bit integer version number. Version numbers returned in earlier builds are always lower than version numbers returned in later builds. Added in version 3. 
getVersionString Returns current Corona version formatted as a human-readable string. It is suitable to be presented to the user. Added in version 3. 
getVersionMajorNumber Returns current Corona version major number. Added in version 3. 
getVersionMinorNumber Returns current Corona version minor number. Added in version 3. 
getVersionBuildType Returns current Corona version build type formatted as string. I.e. one of 'StableRelease', 'ReleaseCandidate', and 'DailyBuild'. Added in version 3. 
showListerDialogtab Opens Corona Lister dialog window. The tab argument determines which tab will be selected when opening the dialog, where 0 means last active tab, 1 means Lights tab and 2 means Scatters tab. Added in version 3.

To invoke a method on proxy object [proxy], use CProxy.ProxyFp.[method_name] [proxy] [optional further args]
Function Parameters description 
getOriginalObjectNameproxy Returns string containing the name of the original object from which the proxy was created. 
getOriginalMaterialNameproxy Returns string containing the name of material of the original object from which the proxy was created.
fromSceneproxy source filename Creates a proxy from scene object source, and saves it to file specified by filename
fromSceneAnimatedproxy source filename frameFrom frameTo pointCloudSize 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 
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 
isSupported[DEPRECATED] Returns TRUE if the library is supported by the running 3ds Max version. Returns FALSE otherwise. Material library is supported in every 3ds Max version except for 2012. This function is available only in Corona 1.7. 
isInstalled Returns TRUE if the library is currently installed. Returns FALSE otherwise (user de-selected it during Corona installation). 
showBrowserIfPossibleshow Displays or hides the browser window for the library, if possible. Returns 0 if it has succeeded, non-zero if it has failed. 
There are several published methods invokable on every CScatter object. You can list them by executing s = CScatter(); showInterfaces s. Look for the ScatterFpInterface interface there. It is available since Corona 3.
Function Parameters description 
updatetimeIntervalreferenceTime Updates scattering of instances for the given non-empty time interval. The specified reference time determines scattering parameters that cannot be interpolated. It is expected to lie in the interval. Returns 0 on success. Returns 1 if the user does not have a valid license. Currently, only 1 time frame long intervals are supported.
clear Clears scattering of instances created by last update call. Can be called to free allocated resources, but maps depending on the scatter object may be evaluated incorrectly then. 
getModelCount Returns number of all model objects. These are original objects that get instanced by the scatter object. The count is relevant to last update call. 
getModelNodeindex Returns node of a model object selected by the given index. If the index is outside [0, N) interval, where N is the count returned by getModelCount, it returns null. The node is relevant to last update call. 
getInstanceCount Returns number of instances. All instances scattered throughout the whole time interval specified for last update call are accounted here. For example, if scattering gets updated for 2 time frames long interval and in the first frame get scattered instances A, B, C and in the second frame get scattered instances B and D, it will return 4. 
convertInstancesToGeometrytime Converts (duplicates) all instances scattered at the given time to true geometry objects. Expects the time to lie in the interval specified for last update call. Returns 0 on success. Note this may be costly for great number of instances. 
There are also several published methods that can be called using the CScatter.StaticFpInterface interface. You can list them by executing showInterface CScatter.StaticFpInterface command.

Corona Renderer 2021Freeware 
Windows/macOS

The current version of Corona Benchmark features the Corona 1.3 rendering core.
Note: The benchmark runs using Corona Renderer 1.3, which is an older version of Corona Renderer – updating the benchmark to a newer version of Corona Renderer would have no impact on the relative performance of 2 different CPUs and would only invalidate all the results gathered so far, so staying with the older version is actually useful from the point of view of a benchmark application. For using Corona Renderer as a render engine, naturally the newer (and faster) versions are better!
Installation and Use
It's easy to use: save, extract, and run the file. https://pendownload.mystrikingly.com/blog/totalfinder-1-7-10-download-free. Benchmark starts to render the testing scene automatically and shows the result at the end, with an option to submit the result to this page. You can also copy it to the benchmark forum thread.
What's New:
Today we have finally updated our standalone benchmark. Download it and share your results now! Compared to the last benchmark we have updated the rendering core, made the scene more challenging, and added easy verification and sharing of render times. Everything is a one-click solution now, no manual copy/pasting required. All times you choose to publish are displayed in a table here. This comes handy especially when you are selecting a new hardware to run Corona.
Corona Standalone Redesigned
From the technical standpoint, the most interesting thing is that the benchmark showcases the possibilities of our new standalone format, which is now much more powerful than ever before. It supports procedural maps, shader networks, and the compressed Corona proxy format for geometry. We are hoping the standalone application will become a viable alternative for distributed rendering some day. You can try it yourself today if you are feeling lucky. Both export and import is a one-click solution, no 3ds Max is necessary, and speedups of up to 30% were reported compared to rendering inside 3ds Max. Some maps are still not supported, but we are working on that.
Conclusion
I would like to thank Robin, who was the primary developer of the benchmark application. That is it; everything left to do now is to download the benchmark and share its results with the community so we can build a comprehensive database of Corona Renderer performance with different CPUs. Stay tuned for the next blog post, in which we will talk about licensing and pricing improvements we have in mind for 2016.
