Maya 2022.4 Update Release Notes

Welcome to Maya 2022.4 Update. You can access the Maya 2022.4 Update from your Autodesk Account.

This release delivers a number of bug fixes, as well as some new features and enhancements.

New Features and Enhancements

This section lists new features and enhancements included in the Maya 2022.4 Update Release. (Or, jump to What's Fixed.)

  • Open Recent File improvements The list of Recent Files displayed at the bottom of the File menu includes two new data points to help you recover crashed files: the name of last file before crash, and the name of the last file saved.

    See Improved crash recovery experience in What's New in Maya 2023 for details.

  • Ability to hide the Home button You can now hide the Home button in Maya using a new preference and Environment Variable, if you find its often accidentally clicked. Turn off Show Home icon in menu bar in the Home Screen section of the Interface Preferences or set the MAYA_NO_HOME_ICON Environment Variable to 1.

    Note: Deactivating this option also suppresses crash recovery messages that appear with the Home icon. They are sent to the Script Editor instead.

    See Hide the Home button in What’s New in Maya 2023.

  • Auto Normalization in the Component Editor A new Auto Normalization menu has been added to the Component Editor to let you turn Normalization on or off using the drop-down menu. This way you can set the value of this attribute for all selected skinCluster nodes at the same time. See Component Editor menus and tabs in Maya 2023 for updated information.

  • Reference Edit updates The Reference Editor window now includes a Show Full Path option. In addition, a -showFullPath option was added to the referenceQuery command.
  • Updates to the Paint Vertex Color Tool Updates in the Paint Vertex Color Tool settings let you restrict painting to individual RGB channels and prevent accidental painting of other channels. In addition, you can now display specific color channels as greyscale using the new Display RGB color set as greyscale option. You can find updated Paint Vertex Color Tool documentation for Maya 2023.1.
  • Run Simulation option in the Bake Animations Options A new Run Simulation option has been added to the Key > Bake Simulation options, to let you have control over whether a simulation will run while baking animation. The simulation is required whenever you bake animation that needs the whole scene to be evaluated at each time step, for example, with dynamics.

    See What's New in Animation Performance for Maya 2023.

  • Isolate Select is now supported for USD For more information on Isolate Select, see Isolate the display of objects or components, and see also the updated Maya 2023 topic Select USD data in the Viewport.

  • Ability to customize Node Traversal depth in the Node Editor A new Traversal Depth option has been added to the Node Editor Preferences to let you specify a depth value for moving through the graph. This is particularly helpful when working with complex structures like rigs.

    See Traversal Depth in the Node Editor Preferences documentation, updated for Maya 2023.1.

  • New Smoothing Groups option for FBX import to retain smooth normal information A new FBX import option, Smoothing Groups, addresses problems where exported FBX polygon objects with smooth edge normals would reimport with incorrect normal information. To preserve shading, activate the Smoothing Groups FBX Export option, and on import, activate the new Smoothing Groups import option. See updated FBX Import Options documentation in Maya 2023.1.
  • New optionVar to resolve relative file paths before absolute By default in Maya the order of attempts at resolving a filename is:

    1. Try an exact path match. 

    2. Try using directory maps (see the MEL command ‘dirmap’) 

    3. Try using reference mappings (checks path against mappings previously provided to the missing reference dialog) 

    4. Try a project relative match. 

    5. Try a base name only match (ie. strip back the base file name and look for the file in the project according to the file type).   

      Two new optionVars are available to control the way in which file paths are resolved: 

optionVar Default Description
fileResolverResolveExactAfterRelative [int] 0 When non-zero, the exact match test will be moved to after the project-relative test. ie. in the above list, step (1) is moved to after step (4).
fileResolverStrictRelativePaths [int] 0 When non-zero, the exact match test will not be tried at all if the path is project relative. Hence a project relative path that cannot be resolved in the current project will be treated as file-not-found, even if the absolute path does in fact exist on disk.
