Deformation after posing with armature Whenever I try to pose this specific bone (the "Hips" bone) the two objects that are weight painted to it deform. I have parented the "Thigh" bones to the "Hip" bone and there is no deformation with those. Does anyone know what is happening, and how to fix it?

Thanks, Felix
Your hips are deforming because their vertices are weighted relatively to two bones: Hips and Spine. When you move the Hips bone the vertices receive two instructions: one (Hips) is telling to move, one (Spine) is telling to stay still: the result is the combination of theese two istances. If you remove from vertices the Spine asignement everything will be as desired. While you're editing your rig I suggest you to have Hips and Spine bones going from down to top (it's a good practice, when you will start animating you'll understand why).
