Harmony 27 Release Notes

Harmony 27, build 25340 (2026-06-16)

New Features

Horizontal Flip in the Reference View

The content of the Reference View can now be flipped horizontally using the Mirror View mode, the same way this mode can be used in the Camera and Drawing views.

Mirroring the content of the reference view allows you to view your reference drawings and designs from the desired perspective. For example, it allows you to flip a character’s design from a left profile view to a right profile, to match the need of your scene.

Improvements

Generate Auto-Matte

The settings last used in the Generate Auto-Matte dialog are now remembered between sessions, allowing you to quickly use the command without having to set the options on every instance. Also note that the list of art layers in the dialog are no longer displayed in reverse order.

Scripting

You can now specify the colour space to use when exporting ProRes files via scripting. HAR-11617

Fixes

General

  • Harmony is blocked from launching on Windows 11 with Smart App Control enabled due to unsigned DLLs. HAR-11692

Compact File Structure

  • 16-bit textures are not supported when using the compact file structure. HAR-11675

Import / Export

  • Selecting "Single Layer" in the Multilayer Image Import Settings dialog sets the transparency to "Premultiply with White" HAR-11648

  • 16-bit grayscale images do not display in the OpenGL view after import. HAR-11645

  • Importing a 32 bits-per-channel PSD produces a corrupted image. HAR-11643

  • Importing a 16-bit grayscale PSD with transparency as a single layer produces a red and green opaque image instead. HAR-11639

  • 16-bit grayscale PSDs do not render unless the transparency type is set to Premultiplied With Black. HAR-11638

  • PSDs saved without the Maximize Compatibility option fail to import and leave a phantom entry in the undo history. HAR-11633

  • Attempting to import a nonexistent PSD silently fails without any user feedback. HAR-10756

Library

  • Deleting a template from a network location in the Library view can sometimes cause a crash. HAR-11694

Nodes

  • When dragging to adjust a layer attribute, the value flickers if the mouse is moved diagonally. HAR-11663

  • Locking a layer from its layer properties takes longer than expected. HAR-11636
