Thank you for your fast response! Would it be possible to just create two characters through the character manager and switch between the two?This are two separate questions. To switch the equipment through code, you can find the required APIs here: https://opsive.com/support/documentation/ultimate-character-controller/artificial-intelligence/
For the character the questions is what you want to do. The easiest way is having multiple meshes / skins sharing the same avatar / skeleton. Then you can simply enable / disable different skinned mesh renderers or replace the mesh.
