Camera Blocking Volume doesn't work for me

Hello,

I have searched a lot about this issues but i can’t find anything that can help me.

I use 2d Paper.

To start, i tried everything from setting the Camera Blocking Volume to changing its Default Value Collision to anything i want to block but doesn’t work.

I tried to use the camera SpringArmComponent’s Do Collision Test but instead of blocking, it blocks (I mean, disappear) every sprites that i put into my level except the character and background and my camera still move after getting into the Camera Blocking Volume.

What i want to do is to block the camera from going pass a certain place or zoom to the character after blocking it (Thought it has never happened but i can imagine it).

An example of what i want is in this old thread, please check it for images:

Thanks for the answer.
