Hello! How are you doing?
At our studio, we don’t have a specific term for this technique because it can be approached in different ways, depending on your needs. To give you a better answer, I have a few questions:
- Can the player or camera instantly enter and exit the building?
- Can the player walk around the building to fully grasp its size and dimensions?
Depending on your project’s requirements, these questions help determine the best approach. Some common methods include:
- Teleporting the player to a new location with a larger interior map
- Using server travel to switch to a different map
- Dynamically loading and unloading separate sublevels
If you have a specific game example, please share it so I can understand your case more clearly.
