Dear Clarisse users,

We are releasing Clarisse iFX 4.0 SP3 today!
As usual, you can download this release from your Download Area.

Clarisse iFX 4.0 is VFX Reference Platform CY2018 compliant.
More information can be found here: http://www.vfxplatform.com

What's new in Clarisse iFX 4.0 SP3:

New Features and Enhancements
Browser
  • It is now possible to create Groups, Combiners, and Shading Layers for items located in a read-only contexts. In that case, the user is prompted to choose a writable destination context. (#9895)
  • Fixed and improved default actions during drag and drop:
    - The default action now takes into account the action "Create Instances Here". The new priority is, move then copy and finally instantiate item(s).
    - Dragging objects with the left mouse button will now correctly move, copy or instantiate the selected items into the target context depending on the item capabilities. Previously, "Copy Here" and "Create Instances Here" didn't work unless using the right mouse button when doing the drag and drop. For example, dragging and dropping an item from a read-only context will now automatically create a new copy if copyable, otherwise, an instance if instantiatable.
    - When items are dragged with right mouse button, the menu now correctly shows in bold the default action. (#9896)
Documentation
  • Updated the tutorial "Embedding Clarisse in a Python Host" with additional information regarding the library path for Linux and macOS platforms. (#9724)
IO
  • Re-enabled copy/paste/localization capabilities of Alembic reference contexts and Alembic referenced items.
    Disabling these features in previous 4.0 versions had proven to be too restricting in existing workflows.
    This will allow again to:
    - copy/paste a referenced Alembic item outside of its source reference context, resulting in a local item;
    - localize a referenced Alembic item instance, resulting in a local item;
    - localize an Alembic reference context;
    - export an Alembic reference context to Project. (#9902)
  • The Alembic exporter has been modified so that its default frame range is set to [0,0] and the number of exported frames is now logged in the export statistics. (#9910)
  • Added a Compatibility Mode option for properties in the Alembic Exporter, and fixed some bugs causing incompatibilities in other 3D DCC applications.
    The new Compatibility Mode option comes with 3 presets for properties:
    - None: default Clarisse mode, property options are editable freely if needed. The default values are recommended for optimal disk and RAM usage, but the exported properties can only be loaded by Clarisse.
    - Houdini: properties will be compatible with Houdini.
    - Houdini and Katana: properties will be compatible with Houdini and Katana. (#9824)
Rendering
  • Unified anisotropy behavior over physical materials. A new attribute (Anisotropy Mode) now allows to choose if the roughness is squashed (old behavior) or stretched (new behavior) when increasing the anisotropy. (#9774)
  • Plane lights can now have a cone angle to mimic barn-doors and behave like a physical spot light. (#9687)
  • Subsurface scattering is now identified as a <WD> event in Light Path Expressions instead of being part of <RD> events. (#9686)
  • Improved massively performances of light path expressions (LPEs) in a highly multithreaded environemnt (e.g. when using a CPU with a lot of cores) (#9646)
  • Added modes for adding/normalizing front and back contributions of the diffuse material and the layers of the multiblend material (#9781)
  • It is now possible in the Multi Blend Material to choose the composition mode (add or over) per layer. New labels are also available for the user to add a description to each layer. These labels are purely cosmetic and do not affect rendering. (#9737)
  • Greatly improved sampling of cylinder and sphere area lights to reduce the noise in the illumination of nearby surface/volume shading points. (#8208)
  • Changed the bit depth from 16 to 32 for some AOVs in order to fix precision issues (depth, world position, motion vectors and sample counts). (#7422)
  • When Clarisse 4.0 was released, a different Adaptive Anti Aliasing scheme than the one described in the user manual was released by mistake. The feedback from the community on this scheme is so positive that we decided to keep it and improve it to make it even simpler to use. Now, when the Adaptive Anti Aliasing is on, the path tracer acts as a progressive renderer. Instead of rendering the image in two passes, all passes are evaluated with a 1 ray per path from the camera. Each path are then accumulated until the pixel variance is under the specified threshold or when the maximum number of samples has been reached. In other words, all sampling information, regarding material/light sampling is ignored. For more information, please read the user manual. (#9514)
Shading Layer
  • Improved greatly shading layer resolutions so that they avoid to be reevaluated when changing the current frame while displaying Alembic/USD items in the 3D View. (#9890)

Bug Fixes
3D View
  • Fixed a regression introduced in 4.0 regarding 3D Layers: 3D Layers were not being updated properly when geometries were driven by custom groups. (#9685)
  • Refresh Mode and Sampling Quality preferences are no longer lost when project is re-saved without change. (#9361)

  • Fixed Background and Foreground plates that were not working anymore in the 3D View. (#9728)
Application
  • Invalid Alembic filename (which happens when the file is not found) are now logged as warning instead of errors unless it is using an invalid extension.

    Fixed a bug that caused layered alembic references to not warn about invalid filenames. (#9616)

  • Fixed a crash that occurred when enabling the render cache in CNode for images that had a relative filename. (#9822)
Expressions
  • Fixed a crash that occurred when removing a custom global variable used in an active expression. (#9909)
  • Fixed a bug where copy/pasting an item using a legacy expression (such as "$PDIR/something/...") resulted in the failure to compile the legacy expression of the pasted item. (#9826)
  • Fixed a bug that prevented expressions set on an attribute of a class to work correctly on newly created items. (#9734)

Geometry
  • Fixed a crash that occurred when using OpenSubdiv on some Alembic bundles. (#9344)
  • Fixed a bug that occured when loading projects created in older versions of Clarisse that contained GeometryFurFile items. GeometryFurFile items were automatically converted to GeometryAbcFur when such projects were loaded in Clarisse 4.0. (#9471)

  • Fixed a crash and illumination of point light in volumes, and added physical mode for point light intensity. (#9324)
  • Handled backward compatibility of previous bug fixes in the "legacy area" spotlight so as to minimize differences in illumination with older scenes. (#9757)
  • Fixed evaluation of the sphere light for rays whose origin is along one of its major axes (e.g., as when viewing the light with a perspective camera placed directly in front of the light). (#9377)
  • Fixed display of point/sphere light in 3D view (#9265)
  • Fixed potential occurrence of NANs when sampling the cylinder light (#9321)
  • Fixed a rendering issue on materials composed of subsurface scattering and specular layers. The subsurface was darker and noisier than expected. (#9834)

Unknown (from forum)
  • Fixed a bug in the interpolation of rotation matrices for Alembic objects that was causing the animation to be sometimes erratic. (#9055)

SDK Changes

  • SDK documentation now has an Events page in the Module section which lists all registered events. (#9150)
IO
  • ModuleScriptedClass::register_scripted_class: added a new optional parameter "is_abstract" to create the new class as abstract. The default value is "false" and the existing code will keep the same behavior. (#9824)
Object Framework
  • Fixed a crash that occurred since 3.6 SP7 when reloading a custom context engine that rename items. Note that if Clarisse no longer crashes, you may get unexpected result on reload (like losing overrides) because of the renaming. (#9752)
Scripting
  • ix.application.get_selection().get_items() now returns the 10 first items when called in PLE mode

    (#9532)
