The hands of my puppet are not attached to the body

Under Body, create a +right arm. Tag the arm draggable (possibly at the wrist). Under the folder +right arm, create a folder Right Hand (no crown). Inside that folder, create your hands.

Now create a Right Hand swap set. Create a trigger (letter) for each hand you want to show, except the default. Now when you drag the Right Arm, the hand you choose (or the default) will move with  it.

Hello
This forum seems to only allow uploading image files.

Please compress your project or puppet into a Zip file
and share it via Google Drive or Dropbox.

A common cause is adding shoulder tags to the arm layer.
Instead of adding shoulder tags to the arm layer, add them to the body layer. This prevents the arms and body from separating.
Please refer to the default puppet, Chloe.
Give it a try.
