No you don't! You don't want the effect... You want everybody that looks at this post to point out that the casing should not be fired from the gun. The effect has nothing to do with the fact that this is all wrong. You probably didn't even render the image but you still need to know that the casing should not be with the bullet. By the way... Have I mentioned that the casing should not be with the bullet. Hey? What's that cool effect on this incredibly incorrect image? It would be more cool if the casing wasn't on that bullet. LOL... Amazing isn't it?
