Unreal PSK/PSA (.psk/.psa)
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
9.1.2 April 9th, 2026

I don't know where to submit a bug. But I will use review as a Bug Submit instead. I wanted to let you know that there's issues with models' shape keys. I have tried to extract models through using Fmodel then I had to import them in Blender 5.0 with your script. It was fine working. But These models get broken shape keys. I have tried everything to fix these issues. But I couldn't get models fixed. Their Faces aren't fully fixed. I'm not sure if it's Unreal Script's or Fmodel's faulty that's causing models to have broken Shape Keys (Morphs). It happened to Texas Chainsaw Game's models when I used Fmodel's new version before and I had to use old version to extracting them with fixed shape keys. But New Games aren't included in old version. I used Fmodel's latest versions to getting Models from new games are supported in only Fmodel's latest versions. I was wondering. Can you fix the script, please? thanks.
really great, though it can't export animations in groups (like Breath2L in Waiting group) so I guess it's not yet fully compatible with Unreal Tournament. still good
Amazing addon! Quick and efficient.
