I am trying to rig this horse model I made (first model I have made as of now) and whenever I try to select a single bone it automatically selects its parents and children bones along with it. I still have to fix the ears, mouth, and tail but before I do that I would like to rig the legs and neck. Please help.
EDIT: I made sure that all my bones were in pose mode. EDIT 2: After much tinkering I got it to automatically assign weights that I could then edit but I could not create my own weights.
