5.0.4

Bug Fixes

• Fixed a bug where it was not possible to export sequences using timeline markers.

5.0.3

Bug Fixes

• Fixed a compatibility issue with legacy PSK files. The PSK importer can now handle both 16-bit and 32-bit point indices in the wedge struct.

5.0.2

Bug Fixes

• Fixed a bug where PSKs with <2¹⁶ wedges and >2¹⁶ vertices would not import correctly (#43)

5.0.1

Bug Fixes

• Fixed a compatibility issue with some versions of Unreal Engine 1 (e.g., used by, for example, Harry Potter and the Chamber of Secrets) that caused the PSK and PSA files to not work when imported into the engine.
• Fixed a bug where PSA import would fail if the PSA skeleton had 2 or more bones with the same name. The add-on will now simply ignore any duplicate bones that are encountered.
• Fixed a bug where the PSA export action list would not be populated if the armature had not had it's animation data initialized.

Miscellaneous

• Added progress indicators when importing and exporting PSAs.

5.0.0

• The minimum Blender version has been incremented to Blender 3.4.0.
• Version 4.3.0 will remain available for download for Blender 2.93 users, but will not receive any further updates since the LTS for Blender 2.93 has ended.

New Features

PSK Import

• Added Import Materials options to the PSK importer. This is enabled by default, but can be disabled to skip the creation of materials during import.

PSA Export

• Pose markers can now be used to mark the start of a sequence for the exporter. This is useful for when you have multiple sequences in a single action.
• Added new PSA Export panel in the action editor sidebar (the "N-panel") with the following options:

Option	Description
Compression Ratio	The key sampling ratio of the exported sequence. A value of 1.0 will sample every frame, while a value of 0.5 will sample every other frame.
Key Quota	The minimum number of frames to be exported.

Action Names

A couple new naming rules have been added for action markers that will affect the export sequence list:

• Action & pose marker names that start with a # character (e.g., #sequence1) will not appear in the export list.
• Action & pose marker names in the form sequence1/sequence2 will add a reversed sequence to the export list. sequence1 will be a normal sequence, while sequence2 will be a reversed sequence. This is useful for when you want to export a sequence and its reverse at the same time without having to duplicate the action.

BDK

• This addon can now work in concert with the BDK addon to import Unreal 1/2 materials from the asset libraries built by the BDK CLI. This feature is experimental.

Cleanup & Removals

• The PSA import functionality has been moved to the File > Import > Unreal PSA (.psa) menu. The PSA Import panel in the Data panel has been removed.
• The Original Names and Trim Sequences options have been removed as they were not particularly useful.
• The Reuse Existing Actions option has been renamed to Overwrite to better reflect its behavior.

Bug Fixes

• Disabling Root Motion now correctly exports the root bone in the bind pose. The description for Root Motion has also been updated to better explain its purpose.

4.3.0

• Added handling for importing PSK MRPHINFO and MRPHDATA sections (i.e., shape keys) emitted from CUE4Parse.

4.2.1

• Unrecognized file sections are now simply ignored instead of rejecting the file entirely. (#32)
• Fixed a bug where it was possible to export a PSK with no bones.

4.2.0

• Added a "Bone Mapping" option. This allows imported PSA actions to map to armature bones with names that differ only by case.
• Improved PSA import speed dramatically.
• Fixed a bug where the root bone orientation would be exported incorrectly.
• Fixed a bug where actions would not be listed for export if its only F-Curve data was for custom properties on a bone.
• Fixed a bug where certain material errors would not display correctly.

4.1.0

• Added an option to bake imported PSA sequences to samples. This is useful for reducing the size of the action data blocks if you don't plan on editing them directly.
• The "Clean Keyframes" option has been removed from the PSA import because it did not work correctly. It will be replaced by a "Decimate F-Curves" option in the future.
• The scene's frame and selected object's active action is now restored after PSA export.
• Added an option to ignore bone name restrictions.

4.0.1

• Bones names can now contain hyphens (-).
