When I try to put a rig on a model but it wont be applied. There are a total of 6 that have an IK rig though in the shot. I just cant add to it for some reason. I did have this problem in the past as well.

Its fine tho. The product is finished.

I did....

I did rotate both the elbow and shoulder, but when i do fix it on one part, it appears to show up again when i play it. When I move the arm in an "unrealistic/wierd way" it goes away. Just gr8.

Sorry for the low quality picture, but you can still see what is going on.

I've been trying to avoid this in my other projects, but now I've reached my limit.
Why does this happen??? When I move the arm "a bit too far" It makes the arm awkwardly shrink. I used the simple rig here.
