When you pose your base armature and generate the rig, it populates the controls and the "green bones" that control them in hidden layers. Now, is it okay to move these green bones to move the controllers for the rig in more fitting areas for the mesh? It's a lot easier than undoing the rig, editing the base mesh, and generating the rig over and over again but I'm not sure if this will cause problems later on.
And side question, why are the bones in these layers green while others are the regular gray color?
