Good to know
How it works
Connect placement terminals or other sets to placements. Each input expands completely in connection order before the next input. Connect the output to World Output, another set, or a Placement group boundary. An empty set contributes nothing.
Identity and reuse
Sets are compile-time wiring: they do not change terminal IDs, salts, placement rules or biome eligibility. The same terminal must occur only once in the active world sequence, even through shared sets; duplicate routes are a compile error. To run a separate program, duplicate its placement terminal or instantiate a group containing it, and choose its salt deliberately.
Scope
A set does not activate a region or infer membership from its name. It has no per-sample execution cost. It is not muteable: bypassing only its first input would silently discard the rest.
