Let say I wanted to make a level-based game taking place inside a bunker. Would I just make the underlying level geometry as one 3d model including all walls, ceilings and floors, or would I divide it into models for each room, or even for each surface?
For reference, I’m coming from older engines like Source or Quake engine, where levels are unique files separate from other entities, unlike modern engines where level geometry is treated the same as any other entity.
I’m assuming this is for a fairly tight, enclosed space, but am mostly concerned with the static level geometry rather than than props or other repeated details. So if I’m understanding right, that would mean generally the geometry is broken into a number of peices, such as each room being a single model.
