Illuminating different parts of the dungeon.

I usually do it this way. I place any static object, like a stone, and then replace its shared property with the one I need. It's the easiest way. Just click the three dots and choose from the list.

Yes, I generally do it the same way. I thought maybe there was a way to make these objects visible in the regular object menu... but oh well, I'll have to stick to the old method. Thanks for the answer.
