Unreal crowd simulations

Hi all!

Im currently tooling with the prebuilt crowd simulation tools within the city scene and was wondering how to change the look of meta human characters, when ever I go into the source of the metahumans it leads me nowhere and im unable to find any tutorials on how to change the randomly generated characters. Any advice or direction much apreciated

Cheers
