I have a house which uses terrain paint in the garage, resulting in an "Incomplete Room" moodlet. The easiest way around this would be invisible floor-tiles.

I couldn't find much in the way of existing tutorials for floor tiles, so I started by cloning an existing floor-tile and emptying it's img files. The game ends up showing this as a solid black tile, rather than invisible. Does anyone know why this is, and possibly how to change it?

You may actually want the "No Unfinished Room Moodlet" mod by Nonamena. I don't currently have the link but if you google this it will pop up I think

Cheers

Thank you for the link, but I don't want to completely disable the moodlet if possible. It helps me figure out when I miss painting/tiling part of a room.
