I used the mirror modifier to make a person but when I added an armature and posed it the 2 halves moves together. How else can I mirror half of the person but have them move separately when animated?
You have to apply the mirror modifier so the mirrored verts become “real” verts. There’s a button on the mirror modifier panel. It should be the first modifier, and you need to do this in object mode.
I can’t find the button.
On the right side of the panel. Says, “Apply”
