Making a Character walk through walls

Hello. I want an Enemy in my Game to be able to walk through walls. The Problem is, I want the Levels to be procedurally generated, wich means that floor and wall have to be the same mesh. Any concepts how I can make my Character walk through walls?

Hello,

You could do a Capsule around the Wall Mesh and when the ‘monster’ hit the capsule, the wall settings are changed from “block all” to “block light volume” (or whatever it is called). Then you need a little delay of ~1.5 seconds and it should switch back to “block all”.
Could be a way, but I don’t have the time, to desing you a BP.

Cheers
