Corona Renderer version 2 Daily Builds Changelog

[Ryuu]

• Fixed CIE to correctly compute resulting alpha channel while merging multiple images.
• Fixed CoronaLayeredMtl layer weight texmaps sometimes not working properly
• Added support for full heterogenous media shading, including multibounce GI inside them. The implementation involves a LOT of new complex code, so bear with us and report any bugs, thanks.
  
  • Currently only single data source is supported - PhoenixFD. We will explore FumeFX, OpenVDB, and 3dsmax texmaps as additional data sources next.

[Ryuu]

• Added Corona toolbar to 3ds Max
• Added console mode for installer and uninstaller
  • To run installer in console mode, use “installer.exe --acceptEulaAndAutoInstall”, this will run the same installation as using the “typical” installation mode in GUI
  • To run uninstaller in console mode, use “uninstaller.exe -q” or “uninstaller.exe --quiet”
  • Both are required to run from console with elevated privileges (admin console)
• New bokeh controls - these were previously ignored in physical camera and now are also added to CoronaCam
  • Center bias (ring effect)
  • Optical vignetting (“cat eye” effect)
  • “Affects exposure” checkbox for custom (texture) bokeh
• Implemented anamorphic factor in Physical camera
• Bladed bokeh now has the same area as the circular bokeh and its rotation is now consistent, independent of camera view
• Lens breathing/Zoom is now taken into account when calculating the aperture size
• Better error description of licensing connection failures (licensing server and corona licensing log)
• Bugfixes
  • Fixed Corona objects not repainting with correct colors when unfrozen
  • Fixed blurring causing artifacts with bright light sources (https://forum.corona-renderer.com/index.php?topic=19127.msg119802#new)
  • It’s no longer possible to create Corona objects with zero size

[Ryuu]

• Speed-up of IR restarts in scenes containing environment lighting
  • The light is no longer reparsed whenever geometry changes. Only changes in geometry with portal material will trigger the reparsing.
• Lights from a light select element can be now selected/deselected via menu accessed by right-clicking the corresponding checkbox in the LightMix tab in Corona VFB.
• Added a maxscript function "showLightMixSetupDialog" to CoronaFp interface for showing the LightMix setup dialog.
• Improved appearance of icons in Corona Toolbar.
• Fixed lens distortion not working properly with crop render region.
• Cubic lens distortion is now correctly applied when computing displacement resolution, evaluating text shader, etc.
• Added support of lens distortion to Standalone.
• Corona Toolbar renamed to Corona Official Toolbar to avoid conflicts with other 3rd-party toolbars
  • In 3ds Max 2017 and earlier the original toolbar (named Corona Toolbar) is not automatically removed to prevent deleting custom toolbars with conflicting names. You will need to delete the original toolbar using Customize > Customize User Interface > Toolbars menu option.
• Fixed alpha being broken when using advanced bokeh efffects

[Ryuu]

• Fixed hair & fur parsing causing crashes when username contains non-ASCII (cyrillic, etc.) characters

[Ryuu]

• The right-click menu allowing to (de)select included lights in VFB LightMix tab is now disabled for light select elements which do not contain any lights
• Improvements to installer and uninstaller when used from command line:
  • Both now support --help command-line argument.
  • When  run in command line / quiet mode (--acceptEulaAndAutoInstall for  installer, --noGui for uninstaller) from non-admin console, an UAC popup window is no longer displayed. An error text is now printed to console  instead.
  • Better error handling of wrong command-line arguments.
• Fixed LightMix setup dialog no longer setting focus to a wrong (non-max) window when it is finished.
• Toolbar
  • Added new buttons
    • Corona Proxy Exporter
    • Corona Converter
    • Create Corona Camera from active perspective view
    • Starts interactive rendering in active viewport
    • Scatter lister
  • Fixed Toolbar in Max 2018 not to pop out on render nodes in case of net rendering (via DR or Backburner).
  • Changed toolbar icon color scheme to blue-white
  • Fixed bad-looking Toolbar icons when switching off Customize > Preferences > "Use large toolbar buttons" option.
• Fixed scrolling issues in combobox on hiDPI monitors
• Fixed render region created from MaxScript not refreshing in VFB until next render

[Ryuu]

• Added support for VRayLight (plane, disk, mesh, and sphere).
  • Note that some options of VRayLight are currently ignored by Corona (for example 'No decay', ...). Basically everything supported by CoronaConverter should also be supported by this new code.
  • Works also without V-Ray being installed (with the exception of light excludes)
• Fixed (un)installer not working with UAC disabled
• Implemented support for real world scale materials. This is just a preparation for the new version of Material Library that will come later. It should not affect current functionality and/or materials. If you notice any changes, please let us know.

[Ryuu]

• Added support for VRayMtl
  • Everything supported by converter script is also supported
  • Works even without V-Ray installed
• Warning about unsupported version of VRayVolumeGrid and/or PhoenixFD split into two separate warnings to more clearly indicate what is wrong
• Added support for PhoenixFD motion blur

[Ryuu]

• Estimated render time is again correctly set when using noise limit (this fixes a bug introduced in previous daily builds)
• Modifying tonemapping/postprocessing overrides in CoronaCamera no longer influences VFB post processing settings in IR when said camera is not used for the rendering
• Fixed noise level in completely noiseless image being reported as ‘unknown’

[Ryuu]

• Added support for FumeFx
  • Only supported versions of FumeFx are 4.12 and newer
  • Corona currently does not support some features, namely motion blur, space warps, illumination maps, channel data shader, etc.
• Fixed renderstamp changed by maxscript not affecting CInfo_RenderStamp when stamp is deactivated in render setup - https://corona-renderer.com/bugs/view.php?id=2983#c5511

[Ryuu]

• CIE no longer applies tone mapping for render elements that should not be tone-mapped.
• CIE now respects disabled Bloom and Glare effects in Render Elements tab in Max's Render Setup.
• Added support for 3ds Max 2019

[Ryuu]

• Fixed curve editor curves not updating when new post processing settings are loaded via VFB “load” button
• Fixed VFB applying incorrectly loaded (invalid) LUTs, resulting in gray/black image
• Fixed Corona IR crash when XRef objects are used
• Fixed incorrect results produced when single map is plugged into multiple UVW randomizer maps: https://forum.corona-renderer.com/index.php?topic=19877.0
• Albedo, SourceColor, and RawComponent elements now properly display shading from Corona Skin Material
• Fixed double clicking on corona buttons (like zoom buttons in VFB) registering just as single click

[Ryuu]

• Fixed crashes when a XRef CoronaCamera is added into the scene
• Corona now supports FumeFx 5.0
• Scatter UI
  • Fixed incorrect tooltip for ‘density’ parameter
  • Disabling certain controls when they’re not used in current mode made more consistent
  • Renamed checkbox "Auto planar mapping" to more descriptive "Override by planar mapping".

[Ryuu]

• Added an option to use 3D-mapped textures for absorption, scattering and emission to CoronaVolumeMtl
• All parameters of newly created CScatter objects are now reset to their default values
• Color curves added to CoronaColorCorrect map

• Corona now supports additional render parameters of PhoenixFD (previously ignored):
  • Step size and shadow step size
  • Option to disable scattering
  • Minimal rendered opacity
• White balance of Physical camera is now applied correctly - setting the temperature of camera equal to the temperature of the light will result in white image (previously the white balance was applied as color tint).

[Ryuu]

• Fixed CoronaBitmap used as CoronaCamera custom bokeh map sometimes not loading during rendering
• Added options for preserving certain materials to material override
  • Material override options are now in a pop-up dialog, accessible from render settings
  • Override can now be excluded from all glass materials, light materials, portal materials, and/or unsupported materials
