I would create a distruction of wood structure when the actor collides with the structure of wood and make collapse of it
Have you tried creating a destructible mesh? If so, what settings have you tried?
If you create a destructible it’s best to keep it reasonably sized and not an entire structure. If you’re just wanting to use physics objects you could set them up in a blueprint. Your question is a little vague, so it’s hard to give you specifics, but feel free to post more information or screenshots to better indicate your end goal and we can help out.
