How to have two inherited meshes in character BP?

In the shooter example project created by epic games, the character BP has two inherited meshes and the default character BP only has one. I think that I need to change the parent c++ class but I don´t know how.

You can have as many mesh components as you want, but yeah I’m not sure about inherited ones - that does seem like a C++ thing to me.

Why is it important for them to be inherited?

You can just create BP children of Character and anything that is a child of that BP will inherit whatever you put in the class above.
