Spawn suppression is the mechanic whereby placed buildings prevent animal and resource re spawns in a set radius.
Foundations 'emit' spawn suppression, but fence foundation and pillars do not, only stopping resources that would intersect with their structure.
For this reason, a player should not build a base or elaborate drop point too close to desirable resources, such as in The Island's volcano crater.
Structures that suppress resources nodes and creatures spawning in a radius:
- Foundation
- Ceiling - pillar with ceiling on top, for example
- Fence foundation with wall
