So I recently modeled a rabbit character and joined all the different pieces (like the eyes, arms, legs, etc.) and then rigged it, following this tutorial.
When I finished rigging, I went into pose mode and rotated the top bone. But the eyes, blush, and left ear didn't move with it. Only the face and the right ear rotated, as shown in the second picture below.
I have searched this up and read this question, but nothing helped. Here are some screenshots of my project:
Picture 1: Rigged character in the t-pose
Picture 2: Rotating the bone
Picture 3: Rotating the spine (Front View)
Picture 4: Rotating the spine (Side View)
Note: Picture three and four are rotated differently so you can see the eyes blush, and nose aren't moving with it.
I was wondering if I had to do some weight painting?
