.PSK - Unreal Engine Character file
.PSA - Unreal Engine Animation file

In order to access these files, you might need an add-on, depending on what program you use.

Recommended tools:
- Blender (Recommended versions: 3.xx): https://github.com/matyalatte/blender3d_import_psk_psa
READ THE README IF YOU ARE UNSURE ON HOW TO PROCEED.
Be aware that some imported animations might move some of the rigged parts all wrong.


- 3DS Max: https://www.gildor.org/projects/unactorx
Donwnload ActorX Importer for 3ds Max. The plugin is then as easy to put on the program as a drag & drop.
