Freezing an animation on a certain frame

So I have a shield defending mechanism in my game, when I hold right click, it activates the defending and plays the shield defending animation.

My problem is, the shield defending animation of course has the model move his shield arm from his side to his front... so when I hold the right mouse button, it loops, and he continuously brings it to the front from the side, rather than keeping it at the front. Is there a way I can freeze it on the frame where the shield is in front of him?

Have you tried setting the animation wrapMode to ClampForever? (you can also change the wrapMode in the editor)
