Hi everybody!

Is there an easy way of making surrounding Water Body (water plugin) rise upon entering a trigger point (On Actor Being Overlap) as a player in Blueprint?

I want to simulate flooding, so that the water level rises and floods the landscape in my level.

Do you guys know why I get this error message?

Best regards!
