How to implement map bounds for RTS Camera?

Hi , I tried that in a new third person template with a pawn blueprint containing camera as the default character. The capsule that was at the end of the spring arm had collision setting set accordingly. There was a blocking volume in the level as well with similar settings. Unfortunately it didn’t work.

So I decided to try moving an actor blueprint instead of a pawn. At level start the actor starts moving toward the blocking volume. But it just passes through the volume as if there’s nothing over there. I’ve attached some screenshots of the settings that I’ve used:

And here’s a video of the actor just cruising through the blocking volume:

I’m somehow getting the feeling that I’m making some simple stupid mistake somewhere.
