This is a paid asset, but now you can download Old Dirty Rooms Free.
Old Dirty Rooms
The new package comes with 2 different environments. There are 41 prefabs in total. The models are well optimised and ready for in-game use. Small objects share a single texture for better optimisation.
Note:
This is an update, the assets from the second environment are interactive. You can open/close drawers and other elements.
Make sure to read the documentation.
