Substructure is a factory automation game, and a good way to get started is to turn one nearby resource into a useful output, then automate its movement before expanding the chain. The game’s systems involve resource extraction, production, conveyors and robotic arms; as exploration opens lower planetary layers, drills and elevators bring vertical transport into the same planning problem. This guide explains how to approach those systems without assuming specific recipes, unlocks or a fixed optimal build order that published coverage does not establish. Steam lists Substructure as an automation game, and a September 2026 preview describes its core systems and planetary layout.
What should you know before automating in Substructure?
Think of automation as managing a flow: resources have to be gathered, moved, processed and delivered where they are useful. Start with a small chain you can inspect, and add machinery or transport only when you can see what problem the addition solves. That approach matters because the game’s systems become interdependent as your factory grows.

Substructure is listed on Steam. A GamesRadar+ preview published September 4, 2026, describes a progression from extracting resources to making products with conveyors and robotic arms, then drilling into additional layers and transporting materials between them with elevators. It also reports that environmental conditions affect production: sunlight speeds plant production, while darkness slows it. These are broad systems, not a published recipe guide, so treat the steps below as a way to reason about your factory rather than a guaranteed tutorial sequence.
The useful beginner question is not simply “Which machine should I build?” It is “What is stopping this resource from becoming useful?” Sometimes the answer is that the resource has not been gathered; sometimes it needs to be moved or processed. Later, it may be that the relevant material is on another planetary layer. Keeping that question in view helps you add only the next part your chain needs instead of building a complicated layout before you know what it must do.

There is no documented universal starting recipe or required machine count to follow here. The examples that are established are silica as an early building material and local fauna as a source of biofuel for more complex buildings. Use them as examples of resource roles, not as a promise that a particular recipe, building, or sequence is available at a particular point in every game build.
How do you start your first production chain?
Begin with resources close at hand and identify one simple input-to-output goal. The preview names silica as an early building material and local fauna as a source of biofuel for more complex buildings, making them useful examples of how early gathering can support later production. It does not specify exact recipes or machine requirements.

Note what is available and what you want to make or support first. Prefer a chain with a clear purpose, such as gathering a building material or supplying fuel, rather than collecting everything without a next step. A useful purpose gives you a way to judge whether the chain is helping: is the material reaching the use you had in mind?
- Trace the material path. Ask what must be extracted, where it needs to go, and what should happen to it next. Sketching that short path mentally—or leaving the machines arranged so the path is obvious—makes missing inputs and blocked outputs easier to spot. Think in terms of source, movement, processing and destination, even if the game’s interface presents those stages differently.
- Get the chain working before making it large. Establish a useful relationship between the resource and its output, then check that the materials reach the next stage. The sources do not establish a universal machine count or an optimal layout, so avoid treating a particular arrangement as mandatory. A small, legible chain also makes it easier to notice whether a problem is with the resource, the route or the destination.
- Automate movement when it helps. Use the conveyors and robotic arms described in the preview to move and handle materials. Keep the first layout easy to inspect: if an input runs short or an output stops moving, you want to be able to see where the flow breaks. Automation is most useful when it removes a repeated handling step or connects stages that need to work together; there is no need to add transport equipment just to make the layout look more elaborate.
- Expand one dependency at a time. Once the chain is useful, add a new resource, production step or route, then check what it changes upstream and downstream. A new building that consumes a material can affect every part of the chain supplying it. By changing one part at a time, you have a clearer chance of identifying which addition created a shortage or blocked route.
The key early habit is to follow materials through the whole chain rather than judging a building in isolation. If a process is not producing what you expect, first check whether its inputs are arriving and whether its output has somewhere to go. That basic flow check is more reliable than guessing at an undisclosed recipe or build order.
For example, if your goal is to support more complex buildings with biofuel from local fauna, think through that goal as a chain: the fauna is the resource, the biofuel is the useful output, and the next question is how the material gets from the resource to the place it is needed. The preview establishes that relationship, but not the exact steps or machinery for producing it. Use the game’s own information to fill in those specifics, and keep the route understandable while you test it.
Similarly, if silica is the resource you want for building, decide whether the immediate goal is simply to gather it or to create a repeatable supply for construction. Those are different planning goals, even if they start with the same material. A modest chain that reliably supplies the next task can be more useful than a larger chain whose output has no clear destination.
How should you compare automation approaches?
There is not enough published detail to name one conveyor arrangement, robotic-arm setup or machine configuration as the best. Instead, compare possible approaches using three practical questions supported by the game’s described systems: how material flows, whether timing or environmental conditions affect that flow, and whether the material must travel between planetary layers.

- Resource flow: A straightforward route is easier to inspect when an input is missing or an output is blocked. Consider whether each added movement step solves a real connection problem or merely makes the chain harder to follow.
- Timing and conditions: A resource that can only be mined at night, or plant production affected by light, is not equivalent to an input you can treat as constant. Compare plans by whether they account for the resource’s timing and conditions, not by an unsupported assumption about exact rates.
- Vertical logistics: If a useful resource is on another level, the elevator route is part of the production chain. Compare a plan that connects source and destination across levels with one that keeps its production local, while remembering that the preview does not provide elevator capacities or placement rules.
This comparison is a planning aid, not a claim that the game offers only these options. It also avoids importing conventions from other factory games: the published preview does not supply machine statistics or evidence that one design is superior. Let the needs and constraints you can observe in your game determine which route makes sense.
How should you handle time-sensitive resources and growing conditions?
Some production decisions depend on when a resource is available or on the conditions around it. Plan those constraints into the chain instead of assuming every input can be gathered or produced at a steady rate.
The preview describes a rock that can only be mined at night and may dissolve if it is not processed effectively. It also says sunlight speeds plant production and darkness slows it. Those examples mean timing can affect both resource collection and the rate of production. The preview does not provide the rock’s name, a precise processing deadline, or detailed production values, so do not rely on an invented schedule or numerical target.
For a time-sensitive resource, think through the sequence before committing to a larger chain: when can it be obtained, where does it need to go next, and what could prevent it from being processed effectively? A night-only collection window and the possibility of the material dissolving make prompt and effective handling a concern, but do not establish a specific timer or exact machine sequence. Watch what happens in your own setup and use the game’s indicators to understand the limits it actually applies.

If the chain appears slower in darkness, that may reflect the environmental effect described in the preview, rather than a broken conveyor or disconnected machine. Conversely, sunlight speeding plant production does not establish a precise output rate or guarantee that every downstream stage can keep up. Follow the material all the way through the chain before deciding where the bottleneck is.
A practical comparison is to separate a timing issue from a movement issue. Ask whether the resource is unavailable at that time, whether it is available but not moving, or whether it has reached the next stage and is not being processed effectively. This keeps your response tied to the observed constraint instead of prompting you to redesign the entire factory at once.

What changes when you explore below the surface?
Going deeper adds a logistics problem: resources may need to travel between planetary layers, not just across one factory floor. In the preview, drills open the crust and help establish elevator shafts, while elevators carry resources up and down.
That makes exploration and transport part of production planning. Before opening a new area, consider what resources there could contribute and how they would reach the chain that needs them. When placing or planning an elevator route, think about where materials enter and leave and how those endpoints connect to production. The source describes elevators and their role but does not establish exact capacity, thresholds, placement rules or a best shaft layout; consult the game’s own interface for those specifics rather than relying on assumed values.
Drilling is therefore more than a way to reveal another area: in the described system, it also helps establish the route for vertical transport. Consider the possible destination for a newly reached resource before treating the new level as automatically useful. If a lower-level resource supports a chain elsewhere, its trip through an elevator and into the receiving production step becomes part of the same flow you would trace on a single level.
Each new level can affect the rest of the factory. A route that adds a useful resource may also add another point where material flow can stall. After establishing cross-level transport, trace the full route—from the source on one level, through the elevator, to the receiving production step—and check that the existing chain still has the inputs and outputs it needs. It can help to think of the elevator endpoints as part of the chain rather than as separate infrastructure: a route is only doing useful production work if material reaches a destination that needs it.
There is no documented numerical elevator capacity or recommended distance between shafts to plan around, and the preview does not establish how thresholds work. Avoid choosing a layout based on guessed throughput or placement limits. Instead, verify the rules in the game and keep your first cross-level connection simple enough to inspect before layering more routes onto it.
How can you spot problems as the factory expands?
When production falters, trace the material path in order: source, movement, processing and destination. This keeps troubleshooting tied to what the system needs instead of prompting a redesign before you know where the flow stopped.

- An output is missing: Check whether the chain’s input is available and reaching the relevant step. Then check whether the output can move onward or is blocked by the way the chain is arranged. If the output is reaching its destination but the result still differs from your expectation, confirm the actual recipe or requirement in the game rather than assuming it from a general factory-game pattern.
- A resource is available only at certain times: Revisit when it can be gathered and whether it reaches the next processing stage effectively. The preview’s night-mined rock is an example of a resource that cannot be treated like an always-available input. Its possible dissolution also makes effective processing worth checking.
- Plant production slows: Account for the sunlight and darkness effects described in the preview. Do not assume a slower rate means the transport route has failed. Follow the chain to see whether downstream stages are simply receiving material at a different rate.
- A new layer is not helping the factory: Follow the material through the elevator route and confirm that its destination is connected to a useful production step. The additional level only contributes if the resource can enter the chain that needs it.
- A new production step disrupts an established chain: Check which existing inputs it draws on and whether the previous output still reaches its intended destination. Add dependencies one at a time so the source of a shortage remains visible.
These checks are a troubleshooting framework based on the described systems, not a list of documented in-game error messages. If the game displays a specific warning or machine status, use that information alongside the material-flow checks. Avoid changing several routes and production steps at once: if the factory improves or worsens, you will have a harder time identifying why.
It is also useful to distinguish a shortage from a blockage. A shortage means the required resource is not arriving in sufficient quantity or at the needed time; a blockage means material is present but cannot move onward as intended. The preview does not define particular warning symbols or exact throughput values, so treat this distinction as a way to inspect the chain, not as a claim about a specific interface feature.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should you avoid assuming?
The published coverage supports a useful high-level starting approach, but not precise optimization advice. It does not establish exact recipes, machine statistics, unlock requirements, resource quantities, throughput values, or a fixed order for building the factory. Those details may be available in the game, but they should be confirmed there rather than filled in from general factory-game conventions.
Likewise, the examples of silica, local fauna, night-mined rock and plant growth do not add up to a documented mandatory progression. They illustrate different planning considerations: building material, biofuel, timing, and environmental effects. The order in which a particular player encounters them, and the requirements attached to each machine or building, are not established by the preview.

Release information also needs care. GamesRadar+ reported the release date as to be confirmed in its September 2026 preview. That is a dated statement, not confirmation of the game’s current availability or release status. Check the official Steam listing for current storefront information.
The preview attributes this design principle to Dubious Design co-founder Stu Taylor: “You need friction for it to be interesting.” In practical terms, the described night-only resource, changing plant conditions and cross-layer transport are constraints to plan around—not evidence that one specific factory layout is correct. The same preview identifies Dubious Design as developer and Hooded Horse as publisher; its release-status statement should be read in the context of its September 4, 2026 publication date.

Frequently Asked Questions
Does Substructure have a tutorial that teaches automation?
The September 2026 GamesRadar+ preview describes automation systems, but does not document the tutorial or onboarding. Check the current game build and its Steam listing for the latest information about what is included.
Is Substructure released yet?
The GamesRadar+ preview published September 4, 2026 listed the release date as to be confirmed, so it does not establish the game’s status now. The Steam listing is the appropriate place to check for current availability.
Can I follow a fixed build order for Substructure?
The published coverage does not give a verified sequence of unlocks or recipes, so a fixed build order cannot be recommended from it. Use the resources and production options actually available in your game, and expand in response to the needs of your current chain.
What are good examples of early resources to plan around?
The preview names silica as an early building material and local fauna as a source of biofuel for more complex buildings. It does not provide exact recipes or machine requirements, so treat those as examples of resource roles and check the game for the specific production steps.
How do lower levels connect to the factory?
The preview says drills open the crust and help establish elevator shafts, while elevators carry resources up and down. Plan how a resource will get from its source on one level to a useful destination on another; exact elevator capacity and placement rules are not documented in the preview.
The Bottom Line
Start with one nearby resource and a clear purpose for its output. Make the material path easy to inspect, then add conveyors, robotic arms or cross-level transport when they solve a real movement problem. Account for night-only resources, plant production that changes with light, and the extra logistics of lower layers. Because exact recipes, requirements and machine statistics are not established in published coverage, verify those details in the game and expand one dependency at a time.
