I've had this mod for a while and have mainly used it to set transparent geometric shapes to create water in bathtubs etc. It worked pretty well in the past, but recently all these effects have disappeared from my homes and I am utterly stuck on how to recreate them. I can't get the horizontal rectangles to appear in a consistent plane that doesn't change with that of my character. I think I will have the "water" line centered properly in my bathtub or whatever, but when I move I discover it's underground, or offset or whatever. I tried enabling the grid, but this only made it more confusing.

I can't figure out what has changed or what I am no longer doing right. I've searched online, and there are a number of essential housing tools videos, but none of them seem to demonstrate exactly what I am trying to do (and was able to do in the past without instruction). Ideally, I'd like a simple, step by step written summary of what to do that is recent and not a few years old, since something seems to have changed with the add on recently.

In short, when placing, rotating, height changing etc, these geometric shapes, how can I tell where it really is and where it will appear to be relative to the furnishing it is accenting?

Thanks!
