How can i dedect is BP overlaping the static mesh wall?

Get overlapping actors node is not working. Because my walls are not BP Actor. They are just static mesh. Is there a way to dedect is BP overlapping with static mesh? Or should i make my walls Blueprint Actor ?

I believe an OnHit event should register.

OnHit event doesnt work. I thought OnHit event is relevant with physyics. Am i wrong?

Not sure to be honest but should be detailed in Docs. I remember using it for similar thing in the past. Not at my work station now. Probably just a checkbox needs flipped somewhere.
