Modular Routers in FTB Skies 2

Modular Routers is a logistics mod built around one block, the Modular Router. Think of it as a super-configurable hopper: you plug in modules and it can pull items from an inventory, send them to other inventories near and far, place or break blocks, drop items into the world, sort items and more. This pack includes version 13.2.7.^[1][2][3]

On its own the router does nothing except act as a one-slot inventory that hoppers and other piping systems can push into and pull from. It only gets useful once you install modules, up to nine of them. Each time the router ticks, it runs every installed module in order. By default that happens once per second.^[4]

What you build it with

• Modules: there are 20 module types. Each has 9 filter slots to control which items it processes, and most have a direction relative to the router's facing.^[5]
• Upgrades: there are 8 upgrade types and 5 upgrade slots in the router. They can speed it up, let it handle more items per tick or extend the range of certain modules.^[4][6]
• Augments: these go into a module rather than the router. Each module has 4 augment slots, and which augments fit depends on the module type.^[5][7]
• Smart Filters: these go in a module's filter slots in place of a regular item. The Bulk Item Filter, for example, can match up to 54 different items. Smart Filter items from FTB Filter System also work in module filter slots in this pack.^[8][9][10]

Who it's for

It's for anyone who wants item automation without a separate machine for every job. Sorting, void filtering, vacuuming up drops and breaking blocks all happen in the same block, just by changing the modules inside. Fluids and energy are covered too, through the fluid and energy modules.^[1][11]

Where it fits in the pack

The pack's "logistics" quest chapter starts with the router itself ("Modular Routers" quest). Every other quest in the chapter unlocks after that one, so you can pick your branches in whatever order suits your base.^[11]

• Item moving: "Pushing & Pulling" quest covers the Sender Module Mk1, Distributor Module and Puller Module Mk1.^[11]
• Router upgrades: "General Router Upgrades" quest covers the Speed Upgrade and Stack Upgrade.^[11]
• Collecting drops: "Vacuum Module" quest covers the Vacuum Module and Fast Pickup Augment.^[11]
• World interaction: "Block Breaking" quest covers the Breaker Module, and "Auto-Clicking" quest covers the Activator Module.^[11]
• Redstone: "Redstone Detection" quest covers the Detector Module.^[11]
• Fluids: "Working With Fluids" quest covers the Fluid Module Mk1 and Fluid Module Mk2.^[11]
• Energy: "Working With Power" quest covers the Energy Upgrade, Energy Output Module and Energy Distributor Module.^[11]

Unverified The sources don't say how early in the pack's overall progression these recipes become available, or whether the pack changes any of the mod's default values, such as the once-per-second router tick.

Welcome to Modular Routers! Think of it as a super-configurable Hopper: one block, the Modular Router, plus plug-in modules that decide what it does. Here is the order I'd build things in this pack, and why.^[3][4]

How the pieces fit together

On its own, the router is just a one-slot inventory. It only does something useful once you install modules, up to nine of them. By default the router ticks once per second and runs every installed module in order.^[4]

Upgrades go into the router itself (it has 5 upgrade slots), while augments go into individual modules (4 augment slots per module). Every module also has 9 filter slots to control which items it handles.^[5][6][7]

Step by step

1. Craft a Blank Module. The router and the modules below are all made from it, so make a few.^[12]
2. Craft the Modular Router and place it down. It's the first quest in the logistics chapter, and every other quest there unlocks after it: "Modular Routers" quest.^[11][12]
3. Make a Puller Module Mk1 and a Sender Module Mk1. Pulling items out of one inventory and sending them to another is the bread and butter of the mod. These modules are part of "Pushing & Pulling" quest.^[3][11][12]
4. Craft a Blank Upgrade, then turn it into a Speed Upgrade and a Stack Upgrade. Upgrades can speed the router up and let it handle more items per tick, which is why they're worth doing early. The pack's quest for them is "General Router Upgrades" quest.^[4][11][12]

Where to go next

Once a basic pull-and-send line works, the same quest chapter offers the Vacuum Module, Breaker Module, Activator Module and Detector Module, plus the fluid and energy modules. For sorting, the Bulk Item Filter can copy the contents of an existing inventory and remembers them even if that inventory is emptied later, which works nicely with a Sender module.^[9][11]

Same as in the All the Mods 10 8.1 guide

The Modular Router is the only block in Modular Routers, and everything else is a plug-in. On its own it's just a one-slot inventory that hoppers and other piping mods can insert into and pull out of. The real work is done by modules, upgrades and augments that you slot into it. Think of it as a hopper on steroids.^[14][15][16]

The router itself, as crafted in this pack.

The router: buffer, slots and ticking

The router has a one-slot buffer that holds up to one stack of items. A comparator placed against the router reads how full that slot is. It also has nine module slots and five upgrade slots.^[18]

Every router tick, the router runs each installed module in order, from left to right. By default a router ticks every 20 server ticks, which is once per second. Each Speed Upgrade shortens that interval by 2 server ticks, down to a minimum of every 2 server ticks (10 times per second).^[15][18][19]

The top-right button in the router GUI sets how it reacts to redstone:^[18]

• Always run, regardless of redstone (the default).^[18]
• Only run when there is no redstone signal.^[18]
• Only run when there is a redstone signal.^[18]
• Don't run at all.^[18]
• Run once when a redstone pulse arrives, meaning any signal higher than the previous one.^[18]

Eco Mode is a toggle that slows an idle router down. The in-game guide says a router that has done no work for 5 seconds then ticks only once every 5 seconds, whatever its Speed Upgrades. As soon as it does any work it returns to normal speed. The guide says both timings are adjustable in the mod config. This is mainly meant for busy servers, but it also suits routers that rarely run, like one collecting sheared wool from a sheep farm.^[18][20]

Unverified The mod's config files aren't among the sources for this pack, so the actual Eco Mode timings and the other config-adjustable values mentioned in this section can't be confirmed beyond what the in-game guide states. Check the mod's config in the pack itself.

Modules and filters

Modules define what the router does. There are 20 module types. Each has 9 filter slots and four augment slots, and many have a direction relative to the router's facing. You open a module's GUI by right-clicking it in hand. You can also hover over an installed module and press the configure key, or middle-click it, without removing it from the router.^[21]

A module only operates if the item in the router's buffer matches its filter (or doesn't match it, when blacklisting). An empty whitelist never lets the module run, and an empty blacklist always does. The filter buttons also control damage matching, item component matching (such as enchantments) and item tag matching.^[20][21]

Termination

Each module has a 'T' button under its filter slots. Normally the router runs all its modules every tick. With termination on, if that module does any work this tick, the router stops there and the modules to its right don't run.^[22]

Moving items: reach and targeting

Pulling and sending modules differ mainly in how far they reach and how you target things:^{[24][25][26][27][28]}

• Puller Mk1 pulls the first eligible item from the adjacent inventory in its configured direction.^[24]
• Puller Mk2 pulls from non-adjacent inventories up to 12 blocks away (24 with range augments), with no line of sight needed. You sneak-right-click the target with the module in hand.^[25]
• Sender Mk1 reaches an inventory up to 8 blocks away (16 with Range Up Augments). The target must sit directly along the X, Y or Z axis, and the router needs clear line of sight. Glass, fences and iron bars are fine, but opaque blocks are not.^[26]
• Sender Mk2 reaches up to 24 blocks (48 with range augments) with no line of sight needed. You target it by sneak-right-clicking the inventory.^[27]
• Sender Mk3 can send to any inventory in any dimension. The target must be chunk-loaded, and the module won't load it for you.^[28]

The Distributor Module is an extended Sender Mk2 that can serve up to 8 targets. You sneak-right-click an inventory to add it and sneak-right-click again to remove it. Its distribution strategies are Round Robin, Random, Nearest and Furthest.^[29]

Recipe id: modularrouters:distributor_module

The Vacuum Module scans a 13x13x13 area around the router, which is 6 blocks in each direction. Range Up Augments can grow it to 25x25x25, and Range Down Augments can shrink it to 3x3x3. If you give it a direction instead of All, the scanned area shifts that way by 6 blocks, plus one per Range Up Augment and minus one per Range Down Augment.^[30]

The Dropper Module drops items from the buffer into the world with zero velocity. The Flinger Module works the same way but adds a configurable speed, pitch and yaw. As an example, a speed of 1.0 with 0° pitch and yaw and a horizontal direction throws an item about 7 blocks along the ground.^[31][32]

The Breaker Module takes its harvest level, and any enchantments, from the pickaxe it was crafted with. An iron pickaxe, for example, won't break Obsidian. By default its filter matches the items a block would drop rather than the block itself.^[33]

Fluids

Routers have no internal tank. They handle fluids through a single fluid container item, such as a bucket, sitting in the buffer. The Fluid Module Mk1 moves fluid between that container and an adjacent block or the world, in either direction. Fluid pipes from other mods can also pump fluid into and out of the container without any Fluid Module installed.^[34]

The Fluid Module Mk2 adds distant targeting up to 12 blocks away (24 with Range Up Augments). You sneak-right-click a block to set its target.^[35]

Recipe id: modularrouters:fluid_module_2

The router's overall fluid transfer rate is 1 bucket per second, with a base of 50 mB/tick. Speed Upgrades make fluid transfers happen more often but in smaller amounts, so they don't raise the total. Each Fluid Transfer Upgrade adds 10 mB/tick, up to a maximum of 400 mB/tick, which means at most 35 of them in a router.^[34][36]

Energy

An Energy Upgrade gives the router an internal FE buffer. The in-game guide lists 50,000 FE of buffer and 1,000 FE per router tick of transfer rate for each upgrade, and says both figures are adjustable in the mod config. Remember that a router tick is not a server tick. With no Speed Upgrades a router tick is 20 server ticks, so real FE/t throughput is lower than the tooltip number suggests.^[37]

Recipe id: modularrouters:energy_upgrade

The Energy Output Module pushes FE into an adjacent energy-accepting block. The Energy Distributor Module can spread it to up to 8 nearby blocks. Both draw from the internal buffer first, or else from an energy-holding item in the router's buffer. An energy item in the buffer can also be charged from the router, or can charge it, using a direction button in the GUI.^[37][38][39]

The guide says modules cost no energy by default, with the exception of the Activator Module in attack mode. Energy costs are configurable, and module tooltips show their usage where it applies.^[37][40]

Augments, upgrades and smart filters

Augments go into a module rather than the router, and each module has four augment slots. Not every module accepts every augment. Some augments can be stacked, and the main ones are:^[21][41]

• Stack Augment: each one doubles the items a module processes per tick, up to the item's normal stack size. It overrides any Stack Upgrades in the router. With 6 Stack Upgrades and 2 Stack Augments, the module handles 4 items per tick, not 64.^[42]
• Range Up and Range Down: each adds or removes one block of range on modules that have a range.^[43][44]
• Regulator: adds a numeric limit so a module only sends, pulls or runs depending on how many of an item are in the target inventory or the router's buffer. On fluid modules it can be a percentage of the tank or an amount in mB.^[45]
• Redstone: lets a single module define its own redstone behaviour, separate from the router's.^[46]
• Fast Pickup Augment: lets the Vacuum Module skip the normal pickup delay of 40 ticks for player-dropped items and 10 ticks for other drops.^[47]
• Pickup Delay Augment: stackable on Dropper and Flinger modules, adding 10 ticks of pickup delay per augment.^[48]
• Mimic Augment: on the Extruder Module Mk2, makes extruded fake blocks take on the properties of the block they imitate.^[49]

Modules operate on a single item at a time: a Sender Module, for example, sends one item from the buffer each router tick, however many are in there. Stack Upgrades and Stack Augments are how you raise that.^[42][50]

Smart filters go in a module's filter slots in place of regular items. The Bulk Item Filter matches up to 54 items and can copy the contents of an inventory, which is handy for sorting systems with a Sender Module. The Mod Filter matches by mod, up to 6 mods per filter. The Regex Filter matches the part of an item's registry name after the colon, with up to 6 entries. The Inspection Filter matches on numeric properties such as durability or fluid and energy level.^{[51][52][53][54][55]}

Protecting your routers

A router with a Security Upgrade can only be opened by players that upgrade whitelists, up to 7 in total including its creator. Placer, Breaker and Activator modules act as a fake player named [Modular Routers] by default. With a Security Upgrade installed they act as the upgrade's owner instead, which plays much better with claim protection on servers. The upgrade doesn't stop a router from being broken, though. A Blast Upgrade makes the router immune to explosions and to being destroyed by boss mobs.^[56][57]

In this pack, everything for Modular Routers lives in the logistics quest chapter. It starts with "Modular Routers" quest, which asks you to get a Modular Router. Every other quest in the chapter unlocks after that one.^[11]

The quest branches

After the router quest, the chapter splits into eight quests. Each one only requires the router quest, so you can do them in any order. Here is what each one asks for:^[11]

• "Pushing & Pulling" quest: the core item-moving trio of Sender Module Mk1, Distributor Module and Puller Module Mk1.^[11]
• "General Router Upgrades" quest: the Speed Upgrade and Stack Upgrade.^[11]
• "Vacuum Module" quest: the Vacuum Module and the Fast Pickup Augment.^[11]
• "Working With Fluids" quest: both fluid tiers, Fluid Module Mk1 and Fluid Module Mk2.^[11]
• "Working With Power" quest: the energy set, with the Energy Upgrade, Energy Output Module and Energy Distributor Module.^[11]
• "Redstone Detection" quest: the Detector Module.^[11]
• "Block Breaking" quest: the Breaker Module.^[11]
• "Auto-Clicking" quest: the Activator Module.^[11]

Module tiers

Three module families have Mk tiers in this pack: Sender (Mk1 to Mk3), Puller (Mk1 and Mk2) and Fluid (Mk1 and Mk2). In each family, the higher tier is crafted from the previous one, so you build the tiers in order.^[12]

The Sender Module Mk1 has two recipes in the pack, so you can use whichever is easier for you.^[12]

Upgrades

A router has 5 upgrade slots, and there are 8 upgrade types. You can put several upgrades in one slot, but each type has its own cap.^[6]

• Speed Upgrade: a router ticks every 20 server ticks by default. Each Speed Upgrade cuts 2 ticks off that interval, down to a minimum of every 2 server ticks.^[61]
• Stack Upgrade: each one doubles how many items a module handles per tick, up to 64 or the item's own stack size. That makes 6 the most useful number in one router.^[62]
• Energy Upgrade: gives the router an internal buffer. Each upgrade adds 50,000 FE of buffer and 1,000 FE per router tick of transfer rate, and both figures are adjustable in the mod config.^[63]
• Fluid Transfer Upgrade: only affects the Fluid Module Mk1 and Mk2. It raises the transfer rate from 50mB/tick in steps of 10mB/tick up to 400mB/tick, so a router holds at most 35 of them.^[64]
• Security Upgrade: limits who can open the router to whitelisted players. The Placer, Breaker and Activator modules then act as the upgrade's owner instead of the default [Modular Routers] fake player, which helps on servers with claim protection.^[65]
• Sync Upgrade: makes routers with the same tuning value and the same number of Speed Upgrades run on the same tick.^[66]
• Blast Upgrade, Camouflage Upgrade and Muffler Upgrade: the Blast Upgrade makes the router immune to explosion damage and to boss mobs destroying it. The Camouflage Upgrade disguises it as another block, and the Muffler Upgrade suppresses sounds and particles.^[67][68][69]

Augments and filters

Augments go into modules to extend what they do. The augment recipes in the pack all start from an Augment Core. The quest chapter only asks for one augment, the Fast Pickup Augment. It works only on the Vacuum Module, you can add at most one, and it lets the module skip the normal pickup delay: 40 ticks for player-dropped items and 10 ticks for other drops.^{[11][12][70][71]}

Once your layout grows, Range Up Augment extends a module's range by one block per augment, and Range Down Augment shrinks it. The Regulator Augment lets you cap how many items a module moves.^[72][73][74]

Smart Filters go into a module's filter slots for more advanced item matching. The pack's Bulk Item Filter is the base for the Inspection Filter, Mod Filter, Regex Filter and Tag Filter, so make that one first.^[12][75]

Everything Modular Routers asks of you in this pack lives in a single quest chapter, "logistics". It's a hub-and-spoke layout: one starting quest, then a fan of side quests that each cover a group of modules or upgrades.^[11]

Start here: the router itself

The first quest is "Modular Routers" quest, and it asks you to get a Modular Router. Every other quest in the chapter comes after this one, so it's your gateway.^[11]

What unlocks next

Once the router quest is done, the rest of the chapter opens up. The quests don't chain into each other, so you can do them in any order you like. Here's what each one asks for:^[11]

• "Vacuum Module" quest: a Vacuum Module and a Fast Pickup Augment.^[11]
• "Working With Fluids" quest: a Fluid Module Mk1 and a Fluid Module Mk2.^[11]
• "General Router Upgrades" quest: a Speed Upgrade and a Stack Upgrade.^[11]
• "Redstone Detection" quest: a Detector Module.^[11]
• "Pushing & Pulling" quest: a Sender Module Mk1, a Distributor Module and a Puller Module Mk1.^[11]
• "Working With Power" quest: an Energy Upgrade, an Energy Output Module and an Energy Distributor Module.^[11]
• "Block Breaking" quest: a Breaker Module.^[11]
• "Auto-Clicking" quest: an Activator Module.^[11]

Unverified The quest data we have doesn't include quest titles, descriptions or rewards, so what each quest gives you on completion isn't confirmed here.

The numeric options in this pack that list a mod default match it, with one exception: the Energy Upgrade values. They only matter if you power routers with Energy Upgrades, but there they make a big difference.^[76]

What the pack changed

• Router.fePerEnergyUpgrade is 150,000 FE of capacity per Energy Upgrade in this pack. The mod default is 50,000.^[76]
• Router.feXferPerEnergyUpgrade is 8,000 FE/t of transfer rate per Energy Upgrade in this pack. The mod default is 1,000.^[76]

Router speed and eco mode

These are all at the mod defaults. A router runs every 20 server ticks (Router.baseTickRate), and each Speed Upgrade cuts 2 ticks off that interval (Router.ticksPerUpgrade). No matter how many upgrades you stack, the interval never drops below 2 ticks (Router.hardMinTickRate).^[76]

A router with eco mode on drops into low-power mode after 100 idle ticks (Router.ecoTimeout). In low-power mode it runs every 100 ticks (Router.lowPowerTickRate).^[76]

Fluid transfer

Routers move 50 mB/t in each direction at base (Router.fluidBaseTransferRate), up to 400 mB/t (Router.fluidMaxTransferRate). Each Fluid Transfer Upgrade adds 10 mB/t (Router.mBperFluidUpgade). These are all mod defaults.^[76]

Module ranges

Every module range in the config matches the mod default. Here are the base range (no range upgrades) and the maximum:^[76]

• Sender Mk1: 8 base, 16 max.^[76]
• Sender Mk2: 24 base, 48 max.^[76]
• Vacuum: 6 base, 12 max.^[76]
• Puller Mk2: 12 base, 24 max.^[76]
• Fluid Mk2: 12 base, 24 max.^[76]
• Extruder Mk1: 16 base, 32 max.^[76]
• Extruder Mk2: 32 base, 64 max.^[76]

Module energy costs

Nearly every module costs 0 FE per operation, including the Breaker, Placer, Vacuum, Void and all the Sender, Puller, Fluid and Extruder modules. The one exception is the Activator's left-click (attack) operation, which costs 150 FE ([[config:config/modularrouters-common.toml#Energy Costs.activatorModuleEnergyCostAttack]]). Its right-click operation costs 0 ([[config:config/modularrouters-common.toml#Energy Costs.activatorModuleEnergyCost]]). These are all mod defaults.^[76]

Gameplay toggles

• Module.breakerHarvestLevelLimit is true. Breaker and Extruder Mk1 modules respect the harvest level of the pickaxe used to craft them, so a module crafted with an Iron Pickaxe can't break Obsidian.^[76]
• Router.blockBreakXPDrops is true, so block-breaking modules drop XP where appropriate, such as when mining ore.^[76]
• Module.dimensionBlacklist is empty. Nothing is blocked for the Sender Mk3 or the Player Module.^[76]
• Module.extruderPushEntities is true, so Extruder modules push entities along when extruding blocks.^[76]

Effects and client settings

Particles are on for the Breaker, Placer, Puller, Sender and Vacuum modules. Extruder sounds and Flinger smoke and sound effects are on too. The bleep volume is 0.5 (Sound.bleepVolume), which is the mod default.^[76]

On the client side, Misc.alwaysShowSettings is true, so module tooltips show their settings without holding Shift. Misc.renderFlyingItems is also true. It looks great, but the config notes that many moving items can cost you FPS.^[77]

FTB Skies 2 1.22.0 ships Modular Routers 13.2.7, and the mod has been in the pack since 1.0.1 or earlier. I don't have any pack changelog entries for this mod, so what follows comes from the mod's own changelogs for 13.2.2 to 13.2.7. Nothing in these sources says the pack changed any of these values.^[2][78][79]

13.2.7

• Fixed an item duping issue when routers containing items are assembled or disassembled to or from a Sable sublevel.^[79]

13.2.5

• Fixed the router GUI going blank if the router blockstate changed (for example active to inactive) while the GUI was open.^[80]
• Fixed the Distributor Module in pull mode not pulling from inventories with oversized itemstacks, such as Functional Storage drawers.^[80]
• Fixed the Fluid Module not transferring correctly from fluid handlers with multiple tanks when a filter is used.^[80]
• Added the modularrouters:player_module_blacklist item tag, which stops certain items being handled by the Player Module. It contains no items by default.^[80]

13.2.4

• Added the modularrouters:activator_blacklist item tag to stop certain items being used by the Activator Module. By default it contains the Acceleration Wand from Not Enough Wands, which the changelog says can be a server-killer.^[81]
• Updated to work with the current release of FTB Filter System (21.1.4).^[81]
• Fixed items sometimes getting lost when clicking in filter screens.^[81]

13.2.3

This was the biggest release of the group. The Activator Module became a range module that accepts Range Augments. Its default base range is 5 blocks for both block and entity modes, and it can be extended to 10 blocks.^[82]

• Fixed the module GUI allowing too many augments into its augment slots, and the router GUI allowing too many upgrades into its upgrade slots.^[82]
