About This Release

We have released Fabric Engine 2.3.1 in order to add support for Maya 2017 (including Update 1) and to add the Fabric for 3ds Max integration. We have taken this opportunity to include a few fixes for issues that were discovered after the release of 2.3.0. Please refer to the Fabric Engine 2.3.0 Release Notes. for more additional information about the 2.3.0 release (for example, other known limitations).

Supported Operating Systems, Integrations and GPUs

  • Fabric 2.3.1 is supported on Windows and Linux. OS X builds are provided but are not officially supported; official support on OS X will arrive in a subsequent release.
  • Fabric for Maya integration is supported for Autodesk Maya 2015, 2016 and 2017 and their corresponding service packs, extensions and updates on Windows and Linux (specifically including Maya 2016.5 and Maya 2017 Update 1). With the addition of support for Maya 2017, Maya 2014 is no longer supported.
  • Fabric for 3ds Max is supported for Autodesk 3ds Max 2015, 2016 and 2017 and their corresponding service packs, extensions and updates on Windows.
  • Fabric for Softimage integration is supported for Autodesk Softimage 2014 and 2015 and their corresponding service packs, extensions and updates on Windows.
  • Fabric for MODO integration is compatible with MODO 901 through to MODO 10.1 and is available on Windows, Linux and OS X.
  • GPU support is available on NVIDIA hardware. See the GPU Compute Guide in the documentation for more details.

Note

Important note regarding gcc compiler version, Maya 2017 and Qt 5:

Should you need to recompile the Fabric for Maya integration and run it with Maya 2017, you must use gcc 4.8. The VFX Reference Platform recommends a patched version of 4.8.2 or 4.8.3; see gcc footnote for details. Previous gcc versions, such as gcc 4.4.7 from CentOS 5, are not supported as they will not correctly build the Fabric for Maya plugin in Maya 2017 (since it does not properly compile the construction of QSizePolicy types).

List of Issues Addressed

Canvas

FE-7189 Old documentation referring to deprecated instrumentation was removed. For correct information, please see http://docs.fabric-engine.com/FabricEngine/2.3.0/HTML/KLExtensionsGuide/FabricStatistics/index.html

FE-7166 Fixed a crash due to unresolved port types

FE-7140 Fixed an issue related to duplicated GUIDs

FE-7130 Removed default content on Array AnyElementMatches so it shows as polymorphic

FE-7114 Expose Count attribute to ForLoop body block by default (having this static value around can reduce the calls to an input array’s size)

Canvas UI

FE-7261 A minor visual bug in the TimeLineWidget (custom FPS) has been addressed

Presets

FE-7260 In a previous release, we removed the PASSIO preset. In hindsight, that was not such a good idea so we have added it back, renaming it to the more sensible name ‘passthrough’

FE-7234 Switch Case has been added to the presets to wrap the KL switch statement

Core

FE-7003 Atan and Atan2 have been added to the trig compounds

FE-7101 A performance regression introduced between 2.1.0 and 2.2.0 has been fixed

Alembic

FE-7244 Houdini normals in curves are now handled by AlembicCurvesReader

FE-7203 Alembic - Maya GPU caches that use uniform sampling are now read correctly

FE-7120 Alembic error messages have been improved

Fabric for Maya

FE-7145 To support Maya 2017, Fabric for Maya links against Qt 5 on Maya 2017 (all the other integrations and standalone remain on Qt 4). If you are building Fabric for Maya or a plugin that relies on it then you must link against Qt 5 for compatibility with Maya 2017 or against Qt 4 for earlier versions.

FE-5923 Exposed ports in Fabric for Maya now inherit the port’s value

FE-6463, FE-7086, FE-7148 Issues with EvalContext that caused crashes in Maya 2016 in parallel eval mode have been fixed. The fix required that string-based members of EvalContext be removed (except ‘host’ which is still available). If you have code that was relying on any of the members that were removed, code changes will be required. See manipulation_drivingports.ma for an example of proper use.
