Today, I added an ingame static mesh for our placeable pool. So now we can physically see what we're placing down as well as delete our water cubes in the game if we don't want them there.

It is now fully placeable and usable. However, I haven't figured out how to delete it yet. Also I'm still working on sizing it so that it will fit in a building in a geometric fashion. And I am also working on adding snap points or something so that it will align with other building parts as well. I am also working on adding physics behind it so you can drink from it and swim in it.
