Renewable material farming: verified reset routes and supply checks

This guide answers one narrow question: can a material route be repeated, and what event makes the supply return? It does not treat every item listed on a location page as renewable. That distinction prevents a one-time facility pickup from being mistaken for a permanent farming loop.

The current Locations reference states that Portal World natural resources reset at midnight between Tuesday and Wednesday and between Saturday and Sunday. Ordinary player-built staging objects persist, while the Cascade Facility sectors do not use this reset. Sandbox settings and future updates can alter a save, so the in-game reset message remains the final check.

Do not extend that general rule into a guarantee for cooking vessels on native stoves. The current Flathill Notes specifically warn that pots or pans left on its stoves will be lost during a reset, along with their contents. Before the reset window, recover both the cookware and its food or water. This is a precaution based on the location's specific warning, not a claim that the cause is known or that every world has the same stove behavior.

Classify the source before calling it renewable

The diagram is a classification aid, not a scale map. Its reset rules and examples are based on the cited version 1.4 pages.

Source types and proof standards

This standard is intentionally stricter than a general item-location list. If one link only proves that an item exists in an area, the page can describe a pickup route but cannot call the route renewable.

Reset-day workflow

1. Wait for the Portal World reset message instead of estimating from real time.
2. Confirm no teammate is still inside the target Portal World near the reset.
3. Empty the destination crate and record the material that is actually blocking the next recipe.
4. Enter with enough free inventory for that material, not every object in the world.
5. Check one known early pickup. If it has not returned, stop the run and verify the save settings or reset timing.
6. Follow the shortest circuit that reaches the target source.
7. Exit when the target amount is met or the route risk exceeds the remaining carrying capacity.
8. Store the haul separately from one-time facility loot so the next shortage can be measured.

This workflow prevents a failed reset from turning into a full empty-world tour, and it gives the group a repeatable way to compare routes without making up drop rates.

The reset rule also excludes worlds occupied by a player or discovered for the first time shortly before the reset. Leave the target world empty beforehand. If its pickup is still missing, check for that exception and wait for a later eligible reset rather than treating the announcement as proof that every world refreshed.

Add a cookware check before leaving Flathill. Empty and remove anything you left on its Industrial Stoves instead of using the reset announcement to test whether a valuable pot survives. A staging crate and a cooking vessel attached to a world stove are different cases in the references; there is no need to risk the vessel to keep the material route repeatable.

Route 1: Flathill office and utility circuit

Flathill is a Portal World, and its item reference documents Power Cells, Staplers, Pens, Enethiol, Hydrochloric Acid, Salt, computers, monitors, and several kinds of office furniture. The same page states that Power Cells return with Portal World resets. This makes Flathill useful when a base needs office components or chemical inputs rather than combat drops.

A practical circuit is:

1. Check the Bounty Basket and its security and office rooms.
2. Cross the Starcade offices and upper storage areas.
3. Sweep the library only if books or salvageable office furniture are part of the target list.
4. Continue through the Syrup Company offices and server area for electronics and office supplies.
5. Use unlocked shortcuts to decide whether the school and remaining roofs are worth the inventory cost.
6. Return through the nearest available exit when the named target is filled.

The detailed Flathill item list is the evidence for the locations. Counts can change with a patch, so the route uses landmarks and item classes instead of promising a fixed haul.

Stop condition: do not salvage every desk and chair merely because Portal World resources reset. Large furniture sweeps consume time and inventory. Stop when the specific shortage, such as Staplers, Enethiol, or computer salvage, has been solved.

Route 2: The Train industrial circuit

The Train documents Axle Grease, Silver Scrap, an Anvil, computers, Military Radios, and Mine Crates among its environment items and resource nodes. Its portal is reached from the Tram Station near the Manufacturing West mines after the Tram Station Key is used.

Mine Crates are the most useful route anchor because the official Mine Crate page documents Steel Cable as a guaranteed crate drop, with Wood Plank, Cloth Scrap, Grinder Disc, Chain, Rebar, Hose, and a Pickaxe as chance-based possibilities. That supports the following route without claiming every item is guaranteed:

1. Enter with tools and space for industrial materials.
2. Search each car for Axle Grease and the placed industrial items you need.
3. Break Mine Crates for the documented drop table.
4. Keep Steel Cable as the predictable crate result; treat all percentage-based items as bonuses, not route guarantees.
5. Leave rare weapons or furniture alone unless they solve a separate need.
6. Exit after the last useful crate or when combat supply is no longer safe.

Axle Grease has a separate verified purpose: the current item page says the Blacksmith exchanges one for one Diode. Check that trade in the current UI before building a route around it.

Failure recovery: if a route produces Steel Cable but no Chain or Rebar, the crate table has not failed. Those are chance-based drops. Reset the Portal World and repeat later, or switch to another documented source rather than inventing a guaranteed count.

Route 3: Mycofields biological-material circuit

The Mycofields lists Anteverse Gel, Anteverse Wheat, Chain, Natural Beehives, and its local entities and drops. It is also described as extremely hot, with lava, and the page recommends heat protection. Several creatures release infectious spores, so a Lab Mask, Mushroom Helmet, or Carapace Helm is also suggested by the source.

Use a target-first circuit:

1. Equip the route's heat and spore protection before entering.
2. Collect exposed Anteverse Gel on the path that can be exited safely.
3. Gather Anteverse Wheat only when cooking, chemistry, or trading has created a measured demand.
4. Fight local entities only for a named drop; do not clear every encounter by default.
5. Use jump pads and known mobility equipment only when the elevated branch contains the target material.
6. Exit before heat, infection, or inventory pressure makes the return unsafe.

Anteverse Wheat also has a separate renewable path. Its official item page says it can be planted and that harvesting in supported Garden Plots returns the plant to a late growth stage instead of requiring complete replanting. A base farm can therefore be a better source than a dangerous Portal World sweep once the crop is established.

Stop condition: if the player only needs wheat, use the established farm. If the player needs Gel or local entity drops, the Portal World route remains relevant. Combining both goals is efficient only when protection and carrying space support the longer trip.

Route 4: Rise medical resupply

Rise documents wall Medkits that respawn through Portal World resets. The source specifically connects those Medkits to renewable Bandages, Healing Syringes, Splints, and Iodine Tablets. Rise also lists Eggs and office furniture, but the medical circuit should stay focused on the wall cabinets when healing supply is the blocker.

1. Open the Rise portal through the optional Cascade Laboratories laser room.
2. Enter after a confirmed Portal World reset with empty medical slots.
3. Check the first known wall Medkit before committing to the full route.
4. Collect the medical item types the group actually lacks.
5. Avoid filling those slots with ordinary office salvage.
6. Return the supplies to a labeled medical crate at base.

The access step requires burning away the invasive goo with Antethermite in the Adjustment Wing before solving the laser lab puzzle; the resulting Rise portal appears at the Lens Epicentre. Inspect each Medkit's contents rather than expecting a Healing Syringe or Splint in every cabinet: the Medkit table lists those two contents as chance-based. A run without either is not by itself evidence that Rise failed to reset.

This circuit has a clear completion condition: the medical reserve reaches its chosen minimum. It is not improved by stripping every room.

Entity drops: verify the entity and the replacement

The Security Bot page documents a guaranteed Security Bot CPU and harvestable Metal Scrap, Tech Scrap, Glass Scrap, Coil, and Robot Oil. It also documents that the bot is normally inactive in its charging pod during the day and patrols at night.

Those facts prove the drop and patrol behavior. They do not justify a rule that all robots everywhere respawn every night. Before calling a local bot a renewable source, defeat it, observe the relevant charging pod across the next cycle in the same save, and account for sandbox settings. The official page even notes a broken Manufacturing West bot near the offices that does not respawn.

If the bot does return, the loop can supply a CPU for current recipes or the documented Blacksmith Anvil exchange. If it does not, classify that particular encounter as a one-time source and move it out of the recurring route.

Trades are conversions, not free renewables

The current Trading page separates fixed NPCs, traveling NPCs, machine exchanges, and special traders. Traveling trader stock can be limited and replenish over time. Quantum Exchangers use a one-to-one chute interaction. These systems do not make an output renewable unless the required input also has a repeatable source.

Use this audit before adopting a trade loop:

For current trader locations and interface differences, use the trader route planner. This farming page deliberately avoids copying a large trade table that could drift out of date independently.

Build a material ledger

A simple ledger turns an anecdotal farming route into a usable plan. Record one line after each run:

Do not publish a drop rate from one or two runs. The ledger exists to choose a route for your save, not to manufacture a universal statistic.
