Populate massive open-world cities and architectural visualisations without modeling individual interiors using the Interior Cubemap System by Roberto Filip. This Unreal Engine 5 shader creates convincing room depth behind flat or near-flat windows as the camera moves.  
The system brings life to urban environments through automated day and night lighting cycles that mimic realistic occupancy. Developers can easily configure room dimensions, assign variations using texture arrays, and layer foreground details like blinds and silhouettes.  

- Features view-dependent room parallax for realistic depth without geometry.
- Includes automated day and night lighting controls with randomized schedules.
- Supports Static Mesh Actors, ISM, and HISM per-instance randomness.
- Offers four optional foreground layers including plants, lamps, and blinds.
