v0.28.1 (2018-06-06)

Added

  • Documentation for mesh export, interpolation modes, and diffing.
  • "-fd" flag added to the import command and the translate command
  • Support for prim var interpolation modes in the import/export code paths (currently UV sets only, colour sets & normals will be in a later PR).
  • Support for diffing all variations of the interpolation modes on prim vars.
  • Routines to determine the interpolation modes on vec2/vec3/vec4 types.
  • AL_usdmaya_LayerManagerCommands to retrieve layers that have been modified and that have been the EditTarget.

Changed

  • Built using USD-0.8.5
  • ProxyShapePostLoadProcess::createTranformChainsForSchemaPrims now checks all the prims' parents' metadata for their unmerged status. If found, the transform chain creation skips the current prim in place of its parent.
  • ProxyShapePostLoadProcess::createSchemaPrims now checks all the prims' parents' metadata for their unmerged status. If found, the schema prim import will instead take place under the parent node.
  • Mesh::import now checks the prim's parents' metadata for its unmerged status. If found, the created shape node will not have the appended "Shape" string.
  • Mesh attributes queries use EarliestTime timecode
  • Functions in DgNodeTranslator are moved to DgNodeHelper in AL_USDMayaUtils
  • AttributeType.h/.cpp are moved to AL_USDMayaUtils
  • LayerManager API has been updated so you can now inspect all layers that have been set as an EditTarget and are Dirty.
  • Updated endToEndMaya tutorial to work with latest USD API changes.
  • All hard coded /tmp paths in the unit tests, in favour of a linux/win32 solution.

Fixed

  • Fix for when tearing down a shape, that it's sibling shapes are left alone in Maya.
  • time1.outTime is now connected to proxy shape nodes when transforms are selected during creation.
  • Selected transforms are no longer renamed when importing a proxy shape.
  • Tests build restored.
  • Fix for Issue "meshTransform cannot execute twice" #82
  • Bug in the import/export of mesh normals
  • Normals export now correctly listen to the exporter options.
  • AL_usdmaya_plugin can be unloaded correctly.
  • Passing the time value into the nurbs, camera, and transform translators on export.

Removed

  • Removed the code that reversed polygon windings if the 'leftHanded' meta data flag was encountered. Instead, the 'opposite' flag is set on the maya mesh.

v0.27.10 (2018-05-07)

Added

  • A new plugin translator (translator/NurbsCurve.cpp) to translate prim between USD and Maya, and write back editing result to USD prim.

Changed

  • Existing static nurbs curve translator re-uses common utils code.

Fixed

  • Windows build

v0.27.8 (2018-05-02)

Changed

  • ExportCommand will now export time samples for the visibility attribute.
  • ImportCommand will now correctly import time samples for the visibility attribute.

v0.27.7 (2018-05-01)

Added

  • Experimental Windows support. It has been tested on Windows 7 with Visual Studio 2015 and Maya 2017.

Removed

  • Qt dependency (Thanks to Sebastien Dalgo from Autodesk)

v0.27.6 (2018-04-13)

Added

  • New attribute "assetResolverConfig" on proxy shape
  • Export creates master geometry prim thus each instance could reference. If transform and mesh nodes are separated by turning off "mergeTransform" option, transform prim will be marked as "instanceable" and fully benefits from usd instancing feature.
  • Import detects shared master geometry prim, ensures maya transform nodes parenting the instancing shape.
  • Layer manager is now serialised on file export

v0.27.5 (2018-04-10)

Added

  • Add assetResolverConfig string attribute to ProxyShape

Changed

  • Built against USD-0.8.4
  • Move initialisation of maya event handler from AL_USDMaya library to mayaUtils library

v0.27.4 (2018-04-04)

Added

  • src/plugin/AL_USDMayaTestPlugin/AL/usdmaya/fileio/export_unmerged.cpp has been added, which tests the mergeTransforms parameter.

Changed

  • src/schemas/AL/usd/schemas/plugInfo.json.in had the metadata "al_usdmaya_mergedTransform" added.
  • src/plugin/AL_USDMayaTestPlugin/AL/usdmaya/test_DiffPrimVar.cpp had the export parameter mergeTransforms changed to 1 to revert to previous test behaviour.
  • fileio/Import.cpp will now check for the mergedTransform metadata on the parent transform, which prevents mesh import from creating the parent transform.
  • fileio/Export.cpp has re-enabled functionality for "mergeTransforms", which will export the Xform prim and then the children mesh prims separately when set to '0'. The parent transform will have the metadata "al_usdmaya_mergedTransform = unmerged" added to tag it as an unmerged node.

v0.27.3 (2018-03-29)

Added

  • Add -eac/-extensiveAnimationCheck option to AL_usdmaya_ExportCommand
  • Add isAnimatedTransform() to AnimationTranslator to perform extensive animation check on transform nodes.

Changed

  • Updated Inactive/Active tests
  • By default AL_usdmaya_ExportCommand will perform extensive animation check.
  • Changed the signature of StageCache::Get(bool forcePopulate) to remove forcePopulate as it doesn't exist in the USDUtilsCache. Also affects Python bindings

Fixed

  • Mesh surface normals were not importing correctly

v0.27.2 (2018-03-27)

Added

  • Internal AL build fixes
  • Small fix to nurb width import

v0.27.1 (2018-03-23)

Added

  • Updated existing command to add layer to the RootLayers sublayer stack
  • Support relative path as usd file path, which will be resolved using current maya file path. It does nothing if current maya file path is none.
  • Renamed glimpse subdivision related tokens (from glimpse_name to glimpse:subdiv:name)
  • Nurb Curve widths now are imported and exported from AL_USDMaya's ImportCommand
  • rendererPlugin attribute to ProxyShape
  • Mesh Translation tutorial

Changed

  • Built using USD-0.8.3
  • Library name AL_Utils -> AL_EventSystem
  • Use custom data to store maya_associatedReferenceNode instead of attribute on the prim when import maya reference.
  • AL_usdmaya_ProxyShapeImportPrimPathAsMaya, removed the parameters which weren't used.
  • Allow for custom pxr namespace - AnimalLogic#68

Fixed

  • "Error : No proxyShape specified/selected " when attempting to add a sublayer via the UI
  • The MPLug::source() error in Maya 2016, the API is only available since Maya 2016 ex2.
  • Failing unit test
  • AL_usdmaya_TranslatePrim now ignores translation to an already translated prim
  • Crash fix for MeshTranslator crash when variant switching
  • Fixes several issues with selection in the maya viewport - AnimalLogic#42

v0.27.0 (2018-03-12)

Added

  • Mesh Translation: Add support for glimpse user data attributes during import / export
  • Added a Translate command "AL_usdmaya_TranslatePrim" that allows you to selectively run the Translator for a set of Prim Paths to either Import or Teardown the prim. Tutorial on the way!
  • preTearDown writes Meshes Translated to Maya to EditTarget
  • Library Refactor: Refactored to seperate code into multiple libraries: see change DeveloperDocumentation

Changed

  • Tests: TranslatorContext.TranslatorContext was failing because there was an extra insert into the context in the MayaReference import. Also there was a filter on the tests which needed to be nuked!
  • Docs: Small update to build.md
  • Mesh Translation: updated glimpse subdivision attribute handling
  • Store maya_associatedReferenceNode in custom data This is to stop USD from complaining about: "Error in 'pxrInternal_v0_8__pxrReserved__::UsdStage::_HandleLayersDidChange' at line 3355 in file stage.cpp : 'Detected usd threading violation. Concurrent changes to layer(s) composed in stage 0x185f5a50 rooted at @usdfile.usda@. (serial=6, lastSerial=12).'
  • Updated AL_usdmaya_LayerCreateLayer command to add layers to Sublayers
  • Proxy Shape and transform nodes names now match
  • Update to USD-0.8.3

Known Bugs/Limitations:

  • Variant Switch with Maya Meshes causes a crash
  • AL_usdmaya_TranslatePrim generates multiple copies of meshes
  • AL_usdmaya_ProxyShapeImportPrimPathAsMaya not using new Mesh Translation functionality

v0.26.1 (2018-03-02)

Added

  • Doxygen comments, tutorial and unit test for ModelAPI::GetLock(), ModelAPI::SetLock() and ModelAPI::ComputeLock().

Changed

Change default lock behaviour of al_usdmaya_lock metadata. "transform" will lock current prim and all its children. -GetSelectabilityValue method is now called GetSelectability -Implementation of ComputeLock() is modified to reuse common code structure. -Library name AL_Utils -> AL_EventSystem

Fixed

  • Issue with the ProxyShapeIimport command not loading payloads correctly.
  • AL_USDMayaSchema's pixar plugin was not being loaded during it's tests
  • Blocked the usd stage being reloaded when the filePath changes, when loading a maya file. This ensures all proxy shape attributes are initialised prior to reloading the stage.
  • Crash when moving a locked prim
  • Locking not working on maya hierarchies that appear and disappear on selection
  • "Error : No proxyShape specified/selected " when attempting to add a sublayer via the UI

v0.26.0 (2018-02-09)

Added

  • Overloads for the MPxTransform::isBounded() and MPxTransform::boundingBox() methods to provide the transforms with a bounding box to enable usage of frame selected

  • Extended Python bindings for ProxyShape class
  • Flag to keep temporary test files generated by AL_USDMayaTestPlugin

Changed

  • Uses USD-0.8.2
  • Reduced the overall number of pulls on the outStage data attribute
  • Replaced the use of MMessage callbacks in favour of a scheduled system allowing control of maya events over a number of plugins and tools
  • the -identifiers/-id flag is set. This makes it more in line with all the other flags for the command (and more flexible), but is a change in behavior - previously, the muted layers would ALWAYS be returned as identifier
  • Removed QT dependency in favour of Maya's keyboard getModifiers command
  • Total revamp of how layers and edited layers are stored by AL_USDMaya

Removed

  • The insertFirst / insertLast concept in the maya events system

Fixed

  • Incorrect spot cone angles were being passed to Hydra in VP2
  • Animated attributes could end up being added to the export list multiple times
  • Ik chains needed to be inspected to ensure the animated values were correctly exported
  • Animation caused via geometry constraints would not be exported
  • regression that printed out various malformed sdfpath errors in unit tests
  • Add AL pkgutil fallback for environments without pkg_resources
  • ProxyShapeImport command now correctly takes ul parameter to direct if it should load payloads or not
  • Bug where it was possible to select a transform outside the proxyshape using the 'up' key
  • Bug with CommandGuiHelper where if it has errors building it would stay hidden, it now deletes and rebuilds itself
  • Bug where addListOption would error if any list items had any characters that need to be quoted
  • Crash when a prim is selected multiple times via command
  • Crash if set xform values on an invalid prim
  • Crash when pushToPrim is triggered but the prim is invalid
  • Crash fix for when switching back + forth between a usd-camera and a maya-referenced camera

v0.25.0 (2017-11-28)

Added

  • New metadata and logic to lock transform and disable pushToPrim.
  • A boolean option "meshUV" or "muv" in AL_usdmaya_ExportCommand to indicate only export mesh uv data to a scene hierarchy with empty over prims.
  • A boolean option "leftHandedUV" or "luv" in AL_usdmaya_ExportCommand to indicate whether to adjust uv indices orientation. This option only works with "meshUV"

Changed

  • Add special rules for some Maya-USD attribute type mismatches so the maya attribute values transfer correctly to USD prim, e.g. interpolateBoundary attribute on mesh.
  • When translate, rotate, scale attributes are locked, TransformationMatrix blocks any changes of these attributes.
  • In mesh import, leftHanded flag retrieved from USD will also decide if uv indices need be adjusted.

Removed

  • Host Driven Transforms

v0.24.5 (2017-11-06)

Fixed

  • Remove leftover file

v0.24.4 (2017-10-18)
