IK Rig (Pole Target Issue) Hello there so i have a mesh with IK set up for the arm however as soon as i add a pole target and go back to Position moving for the IK Arm It Screws up the Mesh this only occurs after adding the pole target it works fine without it. Here's a video so you guys can see exactly what's going on http://puu.sh/tCZCS/3039f37ae6.mp4 Right Click Save as Mp4 

Notice how in the beginning the IK works fine and after the pole target is added it just screws it up why this happen i need to understand what i did wrong also can you add more then 1 pole target in blender?

My main goal is to just have smooth rotations kinda like how IK does it with positioning it doesn't support Rotation Since IK only works for positioning
Turns out using a curve is not a good idea i managed to get it working by using bones only as the pole target and still keeping the chain in shape without distorting like how it was before.
