Hi everybody, I am working to create my first character. 
I am watching the video: CrazyTalk Animator 3 - Character Creation with G3 Template
I used Paint 3 D to create my own character.
One I placed the bones on my character, I used the Layer Manager to duplicate and import (for example) the left arm. 
Suddenly, all the body parts become invisible, but the left arm. If I had the left arm, all the other parts become invisible, but the left hand. 
I understand that it is a question of layers...    I don't know how to resolve this problem, or if there is another way to proceed. 
Many thanks in advance!
