Quick Answer
Voidbloom is the intermediate material that connects Void Petals and Redsand to Fluxite. Current official wording says Voidbloom is created by combining Void Petals with Redsand. To process it, drop the Voidbloom onto the top side of a Flux Emanator. The machine grows a large circular bloom of Fluxite while there is room for that bloom to expand and more Voidbloom continues to arrive. The documented material ratio is exact: 1 Voidbloom always converts to 1 Fluxite.
That ratio does not supply a cycle time or a recommended factory size. Build the route around the confirmed input direction, visible expansion space, and a controlled supply. Avoid older recipes that substitute Amethelis for Void Petals; they do not match the current official Voidbloom page.
What Voidbloom Is
Voidbloom is a processed, slushy material rather than the final upgrade resource. Its official page places it between a two-material combination and the Flux Emanator: Void Petals plus Redsand create Voidbloom, and the Emanator converts that result into Fluxite. This makes Voidbloom useful as a checkpoint in the chain. If it appears correctly before the machine, the mixing stage worked. If it accumulates above the machine without conversion, the problem is at the Emanator interface or its available growth space.
| Chain stage | Confirmed input | Confirmed result | Important condition |
|---|---|---|---|
| Combination | Void Petals + Redsand | Voidbloom | Use the current Void Petals wording |
| Machine feed | Voidbloom | Fluxite bloom begins | Drop input on the top side of Flux Emanator |
| Continued growth | More Voidbloom | Circular Fluxite bloom expands | Space and continued supply must remain |
| Material accounting | 1 Voidbloom | 1 Fluxite | Officially documented as always 1:1 |
The official page does not turn this relationship into a pixels-per-second calculator. It confirms identity, direction, growth behavior, and material conversion. Those facts are enough to design and diagnose a line without guessing at cycle length, machine count, or a supposedly optimal footprint.
Create Voidbloom from the Current Recipe
Use Void Petals and Redsand as the two named ingredients. Keep each material recognizable until the point where they combine, especially when testing a new route. A mixed pile containing unrelated solids makes it harder to see whether the correct pixels met and whether Voidbloom actually formed. Start with a limited amount, inspect the resulting material name in the current game, and only then open a larger supply.
Do not use an old guide that says Amethelis is the direct partner for Redsand in this recipe. Official wiki wording can change during Early Access, and the current dedicated Voidbloom page names Void Petals. This guide therefore treats the older Amethelis recipe as stale rather than presenting two alternatives. It also does not assign an unverified source or recipe to Void Petals. The Planter Box guide covers its own documented Wet Seed and Flower behavior, but that machine should not be described as directly producing Void Petals without a current official source.
When the inputs meet but no Voidbloom appears, check their exact labels first. Similar-looking plant materials are not interchangeable merely because they belong to a broader botanical chain. Remove foreign material, retry the combination with a small pair of confirmed inputs, and record the game version if the live result conflicts with the official page.
Feed the Top of the Flux Emanator
Orientation is not an unknown here. The official Voidbloom mechanics explicitly say the material must be dropped on the top side of the Flux Emanator. Route the finished Voidbloom above the machine and preserve a clear falling path to that surface. Side contact and bottom contact should not be presented as supported alternatives.
Commission the machine in a short sequence:
- Place the Emanator and identify its top side in the current build.
- Clear unrelated pixels from the upper contact area.
- Drop a small, confirmed amount of Voidbloom from above.
- Watch for the circular Fluxite bloom to begin.
- Keep expansion space open before allowing sustained input.
- Confirm the output as Fluxite before sending more valuable material.
This procedure uses the official direction and visible reaction instead of inventing a particular conveyor geometry. Launchers, belts, walls, and buffer shapes can change with the surrounding factory. The invariant is that Voidbloom reaches the machine from the top and the Fluxite bloom has somewhere to grow.
Leave Room for the Circular Fluxite Bloom
The result is described as a large circular bloom of Fluxite, not as a single fixed output tile. Growth continues while two conditions remain true: the bloom has space to become larger, and Voidbloom is continually supplied. A chamber that crowds the machine can therefore stop visible expansion even when the recipe and input direction are correct.
Treat space as a functional requirement, but do not convert that statement into an invented radius or “best” layout. The official source does not publish an optimal clearance, cycle rate, or throughput. Keep the growth region visible during commissioning and add input gradually. If growth stops, inspect both remaining space and the top-side feed before changing the recipe.
The 1:1 ratio describes material conversion, not production speed. Ten Voidbloom correspond to ten Fluxite in the documented accounting, but the source does not say how long that conversion takes or how quickly a particular delivery system can supply it. Separate these questions when evaluating a line: first verify correct conversion, then measure the current build locally if throughput matters.
Diagnose a Stalled Voidbloom Route
Work from the last confirmed state. If Void Petals and Redsand remain separate, the combination stage has not completed. If Voidbloom exists but does not react, check whether it is actually dropping onto the top of the Emanator. If Fluxite appears and then stops expanding, check for blocked space and interrupted Voidbloom supply.
- Wrong recipe in an older guide: use Void Petals plus Redsand, not stale Amethelis wording.
- Voidbloom beside the machine: reroute it to the top-side drop point.
- A small bloom that stops: clear expansion room and confirm continuing input.
- Unexpected total output: compare input and output as a 1:1 material count before assuming loss.
- Unknown timing: measure the live build; no official cycle duration is stated here.
Do not fill gaps with claims about Void Husk, Void Juice, power draw, or exact machine rates. Those details are not needed to explain the verified Voidbloom-to-Fluxite route and are not confirmed by the official sources used for this page. They remain Pending confirmation.
Continue from Voidbloom to Upgrades
Voidbloom is valuable because it is the controlled input for later Fluxite production. Once the bloom is confirmed, use the Fluxite guide to decide how to store and spend the output. Fluxite also exists naturally in small trace quantities, so naturally found material can help before repeatable production is ready. The Emanator route becomes the documented later-game production path.
Keep the intermediate and final material physically or visually distinct. Sending produced Fluxite back toward the top-side input creates confusion even though the machine expects Voidbloom. A visible boundary also makes the fixed 1:1 accounting easy to check. The Flux Emanator guide focuses on commissioning that interface without claiming unsupported timing, cost, or optimal ratios.
