Customizable Stylized Water (Unreal Engine 4)
How to Setup Water Deformation for an Actor
Inside of the Stylized Water Pack Folder go to ExampleMap>ExampleMapAssets
In this folder you will need to find “BP_WaterDisplacmentExample” then open it.
Inside of the Event Graph you will find this bit of code and copy it.
Next you need to find the actor you want to add water deformation to and paste this code into it.
With the code copied the final step is to replace "Cube" with the component you want to effect water with in this case I use the "SkeletalMesh" but you can use what ever component you want as long as it exists in the game world.
Now when playing the game any water material should deform around the given actor.
