Here’s something I’m a bit unclear on, when it comes to modular design: how computationally expensive are modular pieces that are loaded in memory, but not actively rendered due to occlusion/frustum culling? I’m trying to figure out whether I can make a large, multi-story building in a single level and rest content in the fact that since I’m only rendering one room at a time the overall footprint won’t be too big, or whether I need to be very aggressive about streaming assets in and out out memory, perhaps even on a room-by-room basis.
