I'm very new to rigging. I'm trying to rig a model of a spider. I've created a Character, spent ages getting all the components into the right position on the Adjust tab, but when I click on the Binding tab some of the components move out of position. When I go back to Adjust and correct them, then go back to Binding, then move out of place again. I can't figure out what to do to get them to stay in the right place so I can bind them!
