What is Topology?

Topology is the group of layers that make up the characteristics of the ground we walk on in-game.

This includes things such as:

  • If water is fresh or salty.
  • Where nodes can spawn.
  • Where animals can roam.

Topology List

Topology Description
Field Spawns resource pickups, bushes, and some trees
Cliff Blocks everything from spawning
Summit Reduces Tree Spawns (Unconfirmed)
Beachside Spawns some bushes
*Beach Spawns driftwood and boats
Forest Spawns Trees, Mushrooms, Berries, Logs,
Forestside Spawns small trees and bushes
Ocean Defines the ocean area, spawns sea grass
*Oceanside Spawns driftwood (Unconfirmed)
Decor Spawns harvestable ores and decorative rocks (Unconfirmed)
Monument Spawns barrels and food crates
Road Prevents any player buildings and blocks everything from spawning
Roadside Spawns junk piles and bushes
Swamp Spawns swamp trees and sulfur pickups
River Makes water drinkable and adds reeds
Riverside Spawns Pumpkins/Corn and some decor
Lake Makes lake water drinkable
Lakeside Spawns Pumpkins/Corn and some decor
Offshore Spawns underwater clutter, rock formations and sunken ships with loot
Rail Prevents any player buildings and blocks everything from spawning
Railside Spawns dense bushes
Building Blocks everything from spawning
Cliffside Spawns ore nodes and blocks junkpiles from spawning
Mountain Prevents animals, ores and decor from spawning in this area, adds loot barrels (Unconfirmed)
Clutter Spawns harvestable ores and decorative rocks (Unconfirmed)
Alt Spawns Birch/American Beech trees
*Tier 0 Defines the tier 0 area on a map
Tier 1 Defines the tier 1 area on a map, vanilla monuments will spawn better crates
Tier 2 Defines the tier 1 area on a map, vanilla monuments will spawn even better crates
*Mainland Defines where animals can roam and where airdrops can land
Hilltop Unknown/No Use

*Required to make a player spawn point

Notes & Tips:

  • Field Topology defines scrap heli spawns when using the scraptransporthelicopter.population convar

  • Road Topology defines minicopter spawns when using the minicopter.population convar

  • Remove mainland from lakes to prevent animals from walking through!

  • Use Building topology to prevent grass/decor from spawning on underground entrances!

  • Forest topology requires Forest splat in Temperate, Arid, and Tundra biomes, and requires Snow splat in the Arctic biome

Making a valid spawn area

A spawn area is a random location on the map where a "new" character will "spawn" into the game. To make it working you'll need to make an area that has following topologies: Tier0, Oceanside, Beach, and Mainland.

• If the map doesn't have any valid spawn areas then players will spawn at (0,0,0), and probably kicked for InsideTerrain Violation.

Adding road junkpiles to your map

Road junkpiles appear only on a "Roadside" topology. To make a valid spawn area for junkpiles you'll need to paint this topology on any part of the map. It can be done near your roads or somewhere far away from everything – choosing the area is up to you.

Do not make the painted topology too thin – without enough space junkpiles won't spawn there. Keeping the same width as on procedural maps will be enough to get everything working as intended.
