The easiest, but none the less effective, way to optimize a large outdoor scene is setting a view range for an entity. Here are some basic rules that I used during the rebuild of the Return to the Zone project.
- Max: Here you can think of essential buildings and large structures. Think about distant buildings, powerlines, bridges and entities that stick out above the vegetation or water plane.
- Far: Here we have the larger props: containers, trains, vehicles, walls, statues. This also contains props that are exposed in open areas. Think about road side props like stone piles, crates or oilddrums.
- Medium: Props that are placed inside buildings can have either Medium or Near as a view range. When a building has several large indoor areas or contain a lot of windows and doors use the medium setting.
- Near: Tiny props, like cans, toys, garbage and pretty much all props that are placed inside confined rooms.
