How to remove the holes for the caves from the island water plane blue print?

Title says it all?

I’ve copied the default to my mod folder because I want to customize it and remove the holes in it that are used for the caves. How do I do this? Google was unkind to me :frowning:

There is a YouTube dev video that covers water physics volumes. … and he specifically covers this. He shows you the right reference to use that doesn’t have the holes.

Thank you guys!
