Transform a room into just objects.

An option, for after you complete a room, you may turn into "Scene objects".
This is good if you want to make maps, with abandoned structures, that have the terrain and "Outside Room Objects" invading it.

So, for exemple: the workflow would go > Create an Abandoned Ruins > Make let's say an abandoned temple > Work the insides > Turn it into "Objects" so all the walls become solo instances of the wall object. Same with the floor tiles. Same with everything inside.
After that, you can easily, use terrain elevation to make let's say a swampy area that have overtaken a room and such?

Could help making a lot more flexible maps!
