procgen.apply

Finishes a live generator: swaps it, in place, for the asset it makes, the way applying a modifier does. Its current output is written as a durable bundle, and the entity's Generator component is replaced by an Asset component standing that bundle, so the result stands on its own with no graph and no generator. Every generator applied with the same graph, params and frame references one bundle. procgen.bake is the one-shot counterpart that realizes a graph's target without a generator.

entity names the entity carrying the Generator, by id or name.

tools.use("procgen", "apply", { entity = "Box" })

Part of procgen.toolbox, called as tools.use("procgen", "apply", ...) (zero procgen apply in the engine shell). Returns { entity, children, detached, bundle }: the entity's id, its child count with the asset standing, whether the Generator is gone, and the bundle's path.
