brick wall destruction: bad collision

Hi!

I'm starting to learn how to destroy stuff. I made a polygon sphere that goes through a brick wall and I noticed that some bricks don't get affected by the sphere. I checked the collision shape for the sphere and the bricks. It all looks good. I also tried increasing the sub steps to 50 but nothing seems to change.

Something I'm missing?

I would start by increasing the resolution of the sphere. Those large triangle areas might be causing collisions to be missed?

I actually have a lot of subdivisions on the collision sphere.

Also, I'm not sure I understand how collision is interpreted. Is it only getting collisions at the points/vertices? If an object collides with the center of a polygon, does it register a hit?
