Alembic file format support, You can now load save and play back Maya scenes as Alembic. based cache files The Alembic file format is an open source format. developed for exchanging complex 3D geometry data Alembic. files are highly portable and application independent so they can. be shared processed and played back by a number of content. creations applications, In Maya Alembic caches provide a number of performance im.
provements including quicker loading time of large scenes faster. play back of complex character animations and real time play. back of geometry data with topology changes, Alembic files also let you easily share large scenes between various. areas of your production pipeline without the large memory. overhead of fully editable scene files, Options in a new Alembic menu located in the Maya main menu. bar let you configure settings for loading and saving Alembic. Import and export Alembic files page 2,Watch Alembic file import and export. Run Maya with a Simplified Chinese interface, Maya is now available with a Simplified Chinese inter. face For instructions on how to run Maya with a Sim. plified Chinese interface on a different operating sys. tems see Run Maya with a Japanese or Simplified,Chinese user interface page 7.
Import and export Alembic files, You can save and load Maya scene files as Alembic cache files The Alembic. file format is an open source format developed for exchanging complex 3D. geometry data Alembic files are highly portable and application independent. so they can be shared processed and played back by a number of content. creations applications, In Maya Alembic caches provide a number of performance improvements. including quicker loading time of large scenes faster play back of complex. character animations and real time play back of geometry data with topology. changes Complex scenes and animations can be exported as an Alembic file. and then re imported into Maya to improve play back performance and reduce. memory use This workflow lets you easily pass complex scene data to various. areas of your production pipeline such as between animation and simulation. or animation and lighting without the large overhead of fully editable scenes. For example you can export a polygon mesh created from an nParticle effect. to an Alembic file then play the simulation back in Maya solely as a polygon. You can use the Alembic Import and Alembic Export windows to. configure settings for loading and saving Alembic files You can access the. Alembic Import and Alembic Export windows from the Alembic menu. located on Maya main menu bar You can also use MEL commands to import. and export Alembic files, See Alembic Alembic Import page 3 and Alembic Export page 4. To import and export Maya scenes as Alembic files the AbcImport mll and. AbcExport mll plug ins must be loaded Open to the Plug in Manager. Windows Settings Preferences Plug in Manager to ensure these. plug ins are loaded into Maya, For information about loading plug ins see Load or unload Maya plug ins. 2 Chapter 1 What s New in General, Use MEL commands to import and export Alembic files.
You can use the AbcImport and AbcExport MEL commands to import and. export Alembic files For example use the following to export a polygon torus. AbcExport j frameRange 1 120 root pTorus1 file c temp test abc. NOTE When specifying a file path for the exported file in the f argument the. path cannot contain spaces For example you cannot specify. C My Documents maya 2012 Alembic Files,You can instead use C maya 2012 AlembicFiles. Help for the commands is available in the Script Editor using either. AbcExport h and AbcImport h,Related topics,Alembic Alembic Import page 3. Alembic Export page 4,Alembic Import Alembic,Loads Alembic files into the existing scene. Alembic Import Alembic, Opens the Alembic Import window from which you can set options for. loading an Alembic file,Open Opens the selected Alembic file.
Import Imports the selected Alembic file into the current scene. Replace Replaces the selected polygon and NURBS object s with the. Alembic based object s contained in the imported file Only one instance of. each Alembic based object is imported even when multiple objects are selected. in the scene,Alembic Import Alembic 3, Fit Time Range Updates the timeslider range of the current scene to match. the timeslider range of the imported Alembic file, Set Current Time to Start Frame Sets the current time of the scene to the. start frame of the imported Alembic file, Insert Under Current Selection Parents an object selected in the scene to the. imported Alembic based object s If multiple objects are selected the. Alembic based objects become children of the object that is selected first. Debug Prints debug information to the Script Editor window. Related topics,Import and export Alembic files page 2. Alembic Export page 4,Alembic Export, Exports either all objects or selected objects to an Alembic cache file.
Alembic Export All in Alembic and Alembic Export Selection in. Opens the Alembic Export window from which you can set options for. exporting Alembic files Selecting Export All in Alembic exports all polygon. NURBS and subdivision objects in the scene to an Alembic file Selecting. Export Selection in Alembic exports selected objects to an Alembic file. General Options,Cache time range, Render Settings Specifies that your current Render Settings determine the. Cache Time Range, Time Slider Specifies that the current playback range in your Time Slider. determines the Cache Time Range,4 Chapter 1 What s New in General. Start End Specifies that the range of frames between and including the. specified Start and End times determines the Cache Time Range. Start End These fields let you specify a Start and End time for the Cache. Time Range, Evaluate every When creating an Alembic file one sample of your object s. transformations is taken every frame and saved to the Alembic file by default. Evaluate every specifies how often samples are taken during file creation. For example a value of 2 caches the transformations of the current object at. every other frame of the Cache Time Range, Pre Roll Start Frame Specifies at which frame to start the scene evaluation.
Use this option to set the starting frame for time dependent translations that. require run ups,Advanced Options, Don t Skip Unwritten Frames Evaluates every frame regardless of whether. or not there are changes in object translation values between frames. Verbose Outputs frame number information to the Script Editor or output. No Normals When on normal data from the original polygon objects is not. included in the exported Alembic cache file, Renderable When on any non renderable nodes or hierarchy such as hidden. objects are not included in the Alembic file, Strip Namespaces When on any namespaces associated with the exported. objects are removed from the Alembic file For example an object with the. namespace taco foo bar appears as bar in the Alembic file. UV Write When on UV data from polygon meshes and subdivision objects. are written to the Alembic file Only the current UV map is included. Whole Frame Geo When on geometry data at whole frames is sampled and. written to the file When off geometry data is sampled at sub frames and. written to the file This is the default setting, World Space When on the top node in the node hierarchy is stored as world. space By default these nodes are stored as local space. Write Visibility When on the visibility state of objects is stored in the. Alembic file Otherwise all objects are considered visible. Alembic Export 5, A recommended way to use callbacks with the Alembic export is to first define.
a global procedure For example in the Script Editor define the following. global proc perFrameCallback int frame,print frame. The full MEL callback is then,perFrameCallback FRAME. For correct syntax callback commands cannot contain the following. Spaces between characters For example,Single quotes For example. Double quotes For example, Per Frame Callback MEL When each frame is evaluated the string specified. is evaluated as a Mel command For example print FRAME. Post Job Callback MEL When the translation has finished the string specified. is evaluated as a Mel command For example print Done. Per Frame Callback Python When each frame is evaluated the string specified. is evaluated as a python command For example print FRAME. Post Job Callback Python When the translation has finished the string. specified is evaluated as a python command For example print Done. Related topics,Import and export Alembic files page 2.
