Unreal PSK/PSA (.psk/.psa)
Import and export PSK and PSA files used in Unreal Engine.
This Blender addon allows you to import and export meshes and animations to and from the PSK and PSA file formats used in many versions of the Unreal Engine.
Features
- Full PSK/PSA import and export capabilities.
- Non-standard file section data is supported for import only (vertex normals, extra UV channels, vertex colors, shape keys).
- Fine-grained PSA sequence importing for efficient workflow when working with large PSA files.
- Batch PSA import functionality (drag & drop from file system).
- PSA sequence metadata (e.g., frame rate, sequence name) is preserved on import, allowing this data to be reused on export.
- Specific bone collections can be excluded from PSK/PSA export (useful for excluding non-contributing bones such as IK controllers).
- PSA sequences can be exported directly from actions or delineated using a scene's timeline markers or NLA track strips, allowing direct use of the NLA when creating sequences.
- Manual re-ordering of material slots when exporting multiple mesh objects.
What's New
8.1.2 May 7th, 2025
Bug Fixes
- Fixed an error that could occur on PSK export if a material slot was empty.
- Fixed a bug where vertices could be skinned incorrectly in Unreal Engine if the sum of all bone weights for a particular vertex was less than some threshold. (#129)
Miscellaneous
- Improved error reporting when exporting multiple armatures with an incompatible Export Space.
This is bs. i have this installed and yet it errors upon exporting.
Worked like a charm on Blender 4.3. Drag Drop, BOOM! Mother Gooseberry ready for textures.
Love it, but I wish I could import more than one file at a time.
