Blocking volume won't block

I am trying to block a sphere from escaping a confined space.

I have the first person shooter template

I have six static meshes.
4 walls, and a ceiling and a floor
All meshes have a blocking setting of “block all”

I have a sphere with a mass of 10 kg

I have the visibility setting for the meshes set to “not visible in game”. I did this so that I can see what happens when the ball leaves the confining space.

When I shoot at the ball, if I glanse the ball above or beside, the ball will bounce around the enclosed space.

If I shoot at the ball and hit strike the base, it will shoot foward right out of the confining space. The blocking meshes won’t do anything to stop it. Other times it will bounce off one wall, but pass through the one behind me.

Why is this?

I found the answer. You have to enable “continuous collision detection” on the asset that you don’t want to have escape from the bounding box. This can be found under the physics section of the details pane.

Cheers, !
