Get the first Redsand from Redsoil
Look for Redsoil pockets underground, commonly at middle to lower depths. Break the terrain with a digging tool and collect Redsand separately from ordinary Sand. Keep a reserve: throwing it away can leave the Fluxite line short later.
Keep a Redweaver moving
Use the Corraller to catch and release a Redweaver in an accessible collection area. It leaves a Redsand trail while moving. Remove the accumulating output and leave room to turn; a creature boxed in by its own material can stop producing. Start by observing this small collection loop before enclosing it.
Make Voidbloom with vertical contact
Let Redsand fall onto Void Petal, or the reverse. Keep their meeting point above an open receiving area. If the ingredients only sit beside each other on a belt, change the feed height. Send a small completed batch onward before connecting continuous inputs.
Feed and clear the Flux Emanator
Voidbloom belongs at the top of the Flux Emanator. Fluxite grows below it over time. Leave the underside open for growth and harvesting; an occupied output area is not evidence that the recipe is wrong.
Choose a harvesting method for your version
Manual clearing is enough to start the renewable supply. Update 0.5.6 also lets Lava break Redsoil and Fluxite, creating options for automatic harvesting. That patch establishes the interaction, not a guaranteed layout: validate containment, collection and the cooling return separately before leaving a Lava build unattended.
Common questions
Can Redsand become Wet Sand?
The official material reference lists it as not wettable. Keep it out of the ordinary Sand washer.
Why did my Redweaver stop?
Check whether its own output or nearby walls prevent movement. Clear space before adding more creatures.
