i just created and rigged my character, but my character has a hat and some other aparrels, so my question is is there some easy way to bind the hat to the head bone? i tried to parent it to the bone, but then i can't import it to unreal engine properly. Thanks,
You can import them separately, and then create a Blueprint for the character, which contains 2 meshes component (maybe Skeletal for the body and Static for the hat?) and assemble them together.
