The search term Flux refers to Fluxite. Small natural deposits exist underground; the scalable documented route feeds Voidbloom through a Flux Emanator into a reserved collection chamber.
Working route
Fluxite occurs naturally underground in small quantities and can be dug.
The official recipe is Void Petals plus Redsand to make Voidbloom.
Voidbloom must be dropped onto the top of the Flux Emanator.
Each Voidbloom becomes Fluxite, which expands in a growing bloom while it has space.
Questions answered
The official material is Fluxite, used to upgrade tools, weapons, and drones.
Create Voidbloom from Void Petals and Redsand, then drop it on top of a Flux Emanator. One Voidbloom converts to one Fluxite.
The official route needs both continuous Voidbloom supply and free space for the growing bloom.
Redsand is a terrain material that appears in underground layers. Its primary factory use is as one of the two ingredients in the Voidbloom recipe (Void Petals + Redsand = Voidbloom), which is then fed into a Flux Emanator to produce Fluxite. As of Update #3, uncontained Lava destroys Redsoil terrain on direct contact — note that Redsoil and Redsand share the same material family; protect exposed deposits with Basalt containment walls when running nearby Lava routes.
