0.45.0.0

Features

• Added Ramp image node (#2470).

• Added SplinefColor4fPlug type (#2470).

• Added system to backup all open scripts at frequent intervals. This is controlled via the Preferences dialogue (#2469, #2499, #2503).

Improvements

• Viewer :

  • Improved performance significantly when selecting large numbers of objects (#2450, #2486).

  • Improved reporting of errors involving look-through cameras (#2490).

  • Improved camera selection UI (#2490).

  • Added default camera settings dialogue (#2490).

  • Added Ctrl+K shortcut to fit clipping planes to selection (#2490).

  • Added Ctrl+F shortcut to frame selection and fit clipping planes to match (#2490).

  • Added context menu (#2490).

• SceneHierarchy (#2450, #2486) :

  • Improved performance significantly when selecting or expanding large numbers of objects.

  • Multiple selections made in the Viewer are now highlighted properly in the SceneHierarchy (#76).

• Significantly reduced file sizes and load times for scripts containing many shader and/or light nodes (#2455).

• NodeGraph

  • Added ability to Shift+Drag a connection to duplicate it (#2480).

  • Improved representation of Expression, Animation and Random nodes (#2458, #2497).

  • Improved highlighting behaviour for connections to selected nodes (#2473).

• ScriptNode :

  • The current frame is now saved with the script and restored on loading (#2468).

  • Read-only files are now read-only in the UI (#2503).

• ArnoldAttributes : Added attributes to control volume motion blur (#2433).

• Arnold : Added support for OSL shaders with multiple outputs (#2494).

• Stats/Execute apps : By default the current frame stored in the script is executed, rather than frame 1 as before. Use the -frames commandline argument to specify a specific range of frames to execute (#2468).

• CompoundDataPlugValueWidget : Added array types to plug creation menu (#2433).

• Startup : Startup files are now executed in isolated scopes, so they cannot accidentally rely on other startup files (#2462).

• Expression : Python expressions can now read from CompoundDataPlugs (#2484).

Fixes

• Appleseed : Fixed crashes when editing cameras during interactive renders (#2489).

• Browser : Fixed bug caused by missing import (#2449).

• OpenColorIO : Added workaround for OpenColorIO bug whereby config parsing would fail for non-English locales (#1654, #2460).

• Python wrappers : Fixed exception translation (#2459).

• BoxIn : Plug values are now preserved when promoting an input plug (#2461).

• Tractor Dispatcher : Fixed accumulation of tractor plugs on TaskNodes (#2463).

• GraphComponent : Fixed bug which could prevent multiple scripts from being loaded in parallel (#2464).

• GraphComponentPath : Fixed bug whereby children did not inherit the filter from their parent (#2465).

• OSLLight : Fixed metadata for child plugs of parameters (#2474).

• Shader : Fixed serialisation bugs introduced in version 0.43 (#2454, #2455).

• Spline UI : Prevented creation of multiple editing dialogues for the same plug (#2472).

• Added backwards compatibility for scripts referencing the old GafferScene.PathMatcher, GafferScene.PathMatcherData and GafferScene.PathMatcherDataPlug types (#2457).

• Layouts :

  • Fixed incorrect vertical sizing of Timelines in custom layouts (#2502).

  • Fixed bug serialising custom layouts containing special characters (#2492).

• ScriptNode :

  • Hid “frame” plug from the UI, and clarified in the documentation that is not intended for widespread use (#2504).

  • Fixed a bug loading old scripts which referenced IECore::Data types wrapping imath types (#2487).

• Viewer (#2490) : Fixed bug where centre of interest was lost when switching between the default and look-through cameras.

• PlugValueWidget : Fixed bug that allowed drags to be received for read-only plugs (#2503).

• GUI App : Errors are now reported correctly when loading files from the command line (#2499).

• Serialiser : Fixed handling of exceptions in Python serialisers (#2475).

• Expression : Fixed initial UI state so that the expression is not editable until a language has been chosen. This avoids problems where an expression was entered and then lost when the language was set (#2482).

• PlugAlgo : Fixed problems with metadata promotion when using non-Box parents (#2488).

• NodeAlgo : Fixed attempts to apply user defaults to plugs that are not settable (#2507).

API

• PathListingWidget : Added faster expansion and selection methods using IECore.PathMatcher() to store sets of paths (#2450).

• Style : Added state argument to renderAuxiliaryConnection() (#2473).

• Added GafferUI.Backups class (#2469).

• ImageGadget : Added loadTexture() method (#2490).

• ViewportGadget : Added fitClippingPlanes() method (#2490).
