Connecting points to the mesh (Retera's Model Studio)

[Hun_Bableves]

Hi there!

So what I'm trying to do is to create unarmored versions of models and I started it with Maiev.
I managed to remove many elements of it, but now the model is full of holes.


How do I link together the points of the frame? How do I edit the texture? I also managed to cut her ears in half (lol), how can I fix that?

I also removed her weapon vielding arm and copied her other arm, but now it is not part of the animation.
How do I add her right arm to the animation as well?

Any help would be greatly appreciated! Thank you!
