Thanks for the answer))
Of course I know about tile definitions in TiledZed. There is no setting for linking tiles and their overlays.
Only the physical settings of the object itself are registered here. ((and by the way, not all parameters are entered, you need to add what you need to in Users \ IMops \ .TileZed by hand)).
I think there should be some kind of file, similar to Rules in WorldEd, that prescribes the overlay ratios on items. (You need to order the tiles from books & misc to be superimposed on the tiles of the metal shelves when there are items on them (screen 1)
I think a similar situation is on TVs. Something makes them show exactly the desired picture (at the moment when the broadcast is on TV in the game). The TV screen image tiles are on the same tile sheet. (screenshot 2)
PS Sorry for my english.
I suspect language is not very well through the online translator
