[0.3.1.4] Items in underwater condo glow as if in water (when they aren't)

[M3rtman1]

It really bothers me that this happens. (Also, almost all my graphics settings are set to ultra.)
Edit: added the version I was playing on

To accomplish the shimmering effect of the ocean floor (aka, underwater caustics), a graphically cheap solution is to use a decal. What is essentially happening is that a large box encompassing everything on the ocean floor exists down there, and anything inside the box has the caustics effect projected onto it. Individual objects, like walls and floors inside the condo, are exempt from having the caustic applied to them, however, that is not happening to the furniture you place down. That is why this is happening. I will look into a way to fix this. Thanks.
