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.
