Added configurable tone mapping pipeline
  • The tonemapping pipeline is no longer fixed and is composed of multiple independent operators which can be added/removed/reordered in the VFB UI. Any operator can be added multiple times if needed/wanted (e.g. to apply multiple LUTs at the same time, or to save 3 LUTS in one set up to easily turn them on and off for different looks).
  • The default pipeline in new scenes now contains only the most essential operators.
  • Note that the operators are applied from top to bottom, the topmost operator is the first one to be applied to produce the tonemapped image.
  • Added 3 new operators:
    • Advanced Filmic operator - Similar to the legacy Filmic operator, but with more parameters for greated flexibility.
    • Tone curve operator - enhances or suppresses colors based on their intensity (e.g. enhance shadows).
    • ACES RRT (Reference Rendering Transform) operator - suppresses red colors and modifies glow and saturation to make the image a bit more film-like. The RRT operation is normally fixed in the ACES specification, but we have made it configurable for greater flexibility.
  • There are also few presets to show how the tonemapping pipeline can be used to get some interesting results. Few examples of these are attached.
  • Camera overrides are now replaced by the possibility for the camera to have a completely separate tonemapping pipeline. When rendering from a camera that has its own pipeline, the controls in the VFB can be used to modify the camera tonemapping pipeline (previously camera-overriden parts of the tonemapping were just locked-out in VFB).
  • This change makes the tonemapping much more flexible for you as the users as well as internally for us as programmers. This will allow us to easily add more different operators in future releases. Some functionality like bloom & glare or blurring/sharpening remains fixed for now, but will also be moved into the configurable pipeline as additional operators in the future.
  • In legacy tonemapping when the tonemapping was disabled, the exposure was still applied. In the new tonemapping pipeline, the exposure operator is not special in any way, so if the tonemapping is disabled, the exposure will not be applied.

Other changes
  • Added new buttons to the render settings that open license server, my chaos webpage and external utility for setting alternate licensing server addresses and ports.
  • Fixed Corona viewport display filters. There are now both Corona and Non-Corona filters (Command panel -> Display -> Hide by Category)

Note: Remember that we are using the Chaos licensing now, here is how to activate: https://forum.corona-renderer.com/index.php?topic=33839.msg194990#msg194990

Cryptomatte
  • Added warning about using cryptomatte render element in Max to the Cryptomatte render element "Warning: This element displays only a preview in the VFB, for proper use the whole frame needs to be saved in CXR format and then loaded in a cryptomatte-enabled external application as EXR"
  • Removed propagation through reflection/refraction - it did not work previously and there is no clear way how this should work.

General
  • tyFlow now always renders with instancing, even when its “Enable Particle Interface” is turned off
  • The error message shown when the Cosmos browser cannot be open now includes a link to a help page with more information.
  • Fixed mismatch in naming of single-channel float render elements stored in CXR in Corona and their parsing in CIE which previously caused "LEGION STOP" errors
  • Updated visuals in the Corona installer
  • Added new log file, CoronaMax20xx_geometry_parsing.txt, which logs events and objects that took too long (over 3 seconds) to prepare for rendering, parse, displace, etc.
  • Added new button in devel/debug render settings rollout, that shows the memory usage breakdown of Corona, including the objects that take the most RAM in Corona, if currently rendering.
  • Fixed random colors being sometimes produced from grayscale colors by increasing saturation in tonemapping.
  • Fixed IR restarting when tonemapping pipeline is reordered or when operators are added/removed

Scatter
  • Fixed animatable parameters to correctly show in 3ds Max's Track View dialog
  • Reviewed&unified parameters in MAXScript. It breaks backward script compatibility so your scripts will need to be updated for this. This is part of transition from Corona Scatter to Chaos Scatter and is the best time to do so because the transition is not backward compatible anyway.

corona-8-3dsmax-rc1.exe

Chaos Scatter
  • Added 5 scatter presets into Chaos Cosmos platform (into 3D Models > Presets, or search for 'scatter'), 2 for spline scattering and 3 for surface scattering.
    • Can be drag & dropped on target (distribute-on) object or into an empty space (target object gets created then) in the scene.
    • Can be also imported with the Import button, when having the target object selected in the scene.
    • Must be downloaded first, like other assets in the Chaos Cosmos browser.
  • Added camera clipping (optimization) feature supporting various camera types (native, Corona, V-Ray, perspective, orthogonal, fisheye) and also viewport views.
    • Provides 2 modes - Active render camera and Selected camera.
    • In our real-world test scenes, Camera clipping on average lowered parsing time by 25% and reduced Corona memory usage by 17%. Renders cleared faster for the same amount of passes.
  • Added instance editing feature - individual instances can be moved, rotated, scaled, or deleted using a sub-object mode. There is new button for that in Scatter UI too. Should be used for final scatter touches.
  • Removed blank parameters from Track View. Can break backward compatibility.
Corona Converter
  • LegacyMtl->PhysicalMtl conversion is now optional
  • It is now possible to force all converted materials to be either metal or non-metal, instead of relying on the autodetection.
Material library
  • Added 13 new Glass materials
  • Added 33 new Nature materials
  • Added 9 new Plastics materials
Toolbar
  • Toolbar will now reset to an official state once in a while when we make any changes to it. The previous system where we tried to keep the custom user changes by merging them with the official changes unfortunately never worked properly and cost too much to maintain and constantly bugfix, for the little benefit that it actually brought.
  • Added decal icon.
  • Added Cosmos browser icon.
Licensing improvements
  • Implemented trial license activation
  • When no active license is found, we now replace the Corona controls in render settings with a “no license” info text, instead of just hiding them without explanation.
  • Fixed issue where switching tabs in render settings without an active license may take a few seconds.
  • Added more info to the messages in the licensing dialog which pops up on any licensing problem.
Miscellaneous Improvements
  • Added viewport display for triplanar map in both Standard viewport mode (first submap is displayed) and "High Quality" (accurate preview of the shader is used). Unfortunately the "High Quality" mode currently does not work with Corona materials, only standard Autodesk ones. We will fix this in future release
  • Replaced the old Corona color picker with the new one everywhere (e.g. light lister, light mix, etc.)
  • Added saturation randomization to MultiMap
  • Max Improved error message: "unknown/internal error"
  • Make undo / redo work when importing assets from Chaos Cosmos.
Bugfixes
  • Fixed crash when comparing two VFB history images with “Show with original postprocessing” enabled
  • Fixed Advanced Filmic tonemapping operator changing the color even when it is disabled
  • Fixed crash in tonemapping when an operator is dragged below the + button
  • [ColorPicker] Fixed issue where a new color is set to different color slot, when opening another color picker
  • Fixed anisotropy values being set incorrectly on materials imported from Cosmos
  • Fixed issue where rendering material editor while running IR caused licensing problems, and the IR to stop rendering.
  • Fixed NaNs being produced in some very specific cases.
  • Fixed crash when clicking middle/right mouse button while dragging tone mapping operators
  • Fixed IR being restarted when modifying CoronaCamera tonemapping pipeline
  • Fixed tonemapping parameters being reset to their default values when ENTER is pressed while entering the value, when the pipeline was reset previously
  • Fixed randomization of 2-Sided Materials imported from Chaos Cosmos
  • BitmapTex - Fixed crash when adjusting crop parameters linked to linear float controllers
  • Fixed issue where cosmos browser randomly opens up in loaded scenes

Chaos Scatter
  • Fixed length-based parameters, like spline spacing in 1D scattering, to correctly handle scene units. Note scenes created/saved in RC1 remain unfixed, as values of those parameters are corrupted. We are sorry for that. You will need to download scatter presets in Comos browser again too.
  • Fixed editing instances not to clear on changes of materials assigned to target (distribute-on) objects.
  • Fixed the viewport icon being two times smaller during placing.
  • Fixed Include/Exclude spline checkboxes to update properly in animations.
  • Added help button to scatter toolbar.
  • Changed default rotation in Z axis (only) to 360 degrees (in everyday use number of cases where randomized rotation in Z is required is vastly greater than number of cases when it needs to be fixed).
Corona Converter
  • Fixed Corona Converter converting LegacyMtl with black refraction color and non-zero refraction amount into refractive PhysicalMtl
Tonemapping
  • Improved post processing UI in Render Setup (removed Tone mapping group and left only the button there)
  • Fixed issue where right-click during dragging of tonemapping spinner reset the value to the default value. Now it resets to the value before dragging started.
  • Fixed tonemapping operators sometimes changing order when clicking the mouse around the VFB
  • Fixed two LUT tonemapping operators swapping their paths when their positions are swapped
  • Fixed tonemapping pipeline in VFB not being updated when switching cameras while IR is running
  • Fixed tonemapping not being properly updated when a new camera with override is created while IR is running
  • Remapped the glow parameter of the ACES RRT tonemapping operator to make it more linear in the UI
  • Removed check for black tint
  • Returned loading of exposure type from legacy scenes (cca 2015 and older)
Cosmos
  • If you open the Cosmos browser while Corona is not set as the active renderer you will be prompted to switch the active renderer to Corona.
  • Fixed Cosmos Browser complaining about unknown / invalid importer after update of Cosmos Service
  • We now use HTTPS protocol when connecting to Cosmos Server from Cosmos Browser
  • Fixed bug where triplanar was repeatedly applied and was using wrong scaling in real world scale
