Yes, you can export the character and cloth through unreal itself. However, exporting a customized character is not possible at the moment (since it exists at runtime). UE4 sadly doesn’t allow exporting with specific morph targets set. However, having something like this (also to support some sort of “baking” process for optimization) is being investigated. Though this will take some time and most likely only be possible through C++.
I am currently working on a tutorial for this. It will be completed & released after everything has been wrapped up with the new female character.
