Depth Only Camera re scaling arms

Hello, I know my question is not really detailed because I don’t know how to explain this:
I searched on google how I can make the hands in my game not to collide with any walls I followed the “tutorial” everthing is working fine but when I look down or up my gun and arms become all tiny I tired to play a little with the camera settings without success:

Thanks for trying !

I found the solution, when moving the camera up and down the parent of the arms move too so you just need to parent it to a object that does move when the camera is down or up.
