Hey so for anyone interested I created a plugin for merging meshes as in the ue4 docs the code for doing so is kind of outdated if you are interested you can download the plugin from my github as for now for ue4.21
Here is the link:
One problem I haven’t been able to take care of is the matter that when one of the body parts is a cloth part it won’t be simulated as cloth after merging together.
If I get any updates on this I will inform you.
Kind regards
Luis
