Bug Fixes

• Fixed a bug where the root bone would be oriented incorrectly in PSA exports.

Changelog

Multiple Armature Support

Support has been added for exporting PSKs and PSAs from multiple armatures. This has been made possible by the addition of slotted actions in Blender 4.4.

In future, a PSA collection exporter will be added to allow for more repeatable PSA exports, as it is currently a little clunky to select multiple armatures and manually go through the export process.

Note that because PSKs need to have a single root bone, the exporter will automatically insert a root bone at origin with an identity transform. The name of this bone is ROOT by default, but can be changed in the export options.

PSK Export

• Added Material Order Mode option to the PSK export options. This allows the user to choose between Automatic (default) and Manual.

PSK Import

• Multiple PSK files can now be imported at once using the drag-and-drop method.

PSA Export

• Added support for handling action slots in Blender 4.4.
• Users can now define a custom compression ratio (via new Compression Ratio Source option).
• Added Sampling Mode options (subframe vs. interpolated).
• Actions with a name that starts with ! will now also only export the first frame (same behavior as timeline & pose markers).
• Added a warning when the user hasn't selected any sequences to export.

Bug Fixes

• Fixed a bug where bone collections might not be displayed correctly in the PSK collection exporter.
• Fixed incorrectly oriented exports when using non-default Forward Axis & Up Axis options.
• Fixed a bug where users would not be able to export a PSK unless it had an armature modifier.
• Fixed a bug where material slots would be empty if the user had the BDK addon installed and the material look-up failed.

API

• All operators have been organized into two separate bpy.ops.psa and bpy.ops.psk namespaces.
• In order to better accomodate user automation, a new bpy.ops.psa.import_all operator has been added that imports all the actions in a PSA file.

Miscellaneous

• Automated testing has been added to pin behaviors and prevent regressions of key functionality. This should result in increased confidence to release incremental updates more frequently.

Changelog

Additions

PSK Export

• Added handling for exporting geometry from Collection Instances.
• Added Scale option.
• Added Export Space option with the following options:
  • World - Export the model in world coordinates.
  • Armature - Export the model in the armature's local coordinates.
  • Instance - Export the model in world coordinates, offset by the collection's Instance Offset.
• Added bone collection filtering to the Collection Exporter.
• PSKs can now be exported without materials.

PSA Export

• Added Active Action as the sequence type, allowing the user to select multiple armatures with the same data block and export the active action for each one.
• Added a Scale option for when exporting animations for an armature that had been scaled on export.

Bug Fixes

• Fixed Blender 4.3 compatibility error.
• Fixed an error that would occur if selected armatures had no actions or animation data when exporting PSA.

Changelog

Bug Fixes

• Fixed an error that could occur for some users when importing PSKX files (#113)

Changelog

Bug Fixes

• Fixed a bug where PSA config files would be ignored if the names of bones contained dashes.
• Fixed an error when checking whether or not the BDK addon was installed.

Additions

• Added support for importing multiple PSA files by drag & drop.
• Added Visible Only option to PSK collection exporter.
• Added Translation Scale option to PSA importers.

Changelog

Additions

• Added support for Collection Exporters.

Changes

• Vertices without explicit weights are now weighted to the root bone. This fixes an issue on some older versions of Unreal (e.g. Postal), where the engine does not handle vertices with no weights, resulting in corrupted meshes.
• The PSA export dialog now has collapsible panels.
• Updated BDK repository support.

Changelog

Initial release for Blender 4.2 extensions compatibility.

Bug Fixes

• NLA Track Strips would not correctly populate when using "Animation Data Override".
• "Compression Ratio" and "Key Quotas" were not being correctly evaluated on NLA Track Strip sources.

Changes

• Pose markers that begin with ! character will now only export the first frame.
• Imported PSKs will now have their first UV layer named UVMap instead of VTXW0000.
• Selected non-mesh objects will now be ignored on PSK export instead of blocking the operator from being invoked.
