Can’t see all of it at once. How exactly to implement this would depend on the game itself. For example, here are some questions I’d ask myself if I were the developer for this game:
- If the player is outside of a building, do they need to see the furniture on the inside?
- If a player is far away from a detailed element, do they need to see all of the detail?
- How far away can the user usually see? If their view is often obstructed by walls or other barriers, do they need to see what is on the other side?
The answers to questions like these would also answer your question. The client would not see all of it because they would not need to see all of it, and the performance of the game is more important to them.
