Modular Routers in FTB StoneBlock 4

Modular Routers is a flexible mod for moving items, fluids and energy around the world. Think of it as a super-configurable hopper on steroids. This pack includes version 13.2.7.^[1][2][3]

It all starts with one block, the Modular Router. On its own it only acts as a one-slot inventory that hoppers and other piping systems can fill and empty. To make it useful, you plug in up to nine modules.^[4][5]

Every time the router ticks, it runs each installed module in order. The in-game guide says that is once per second by default. Each module works on the item in the router's buffer or on the world around the router.^[4]

What you can do with it

• Pull items from an inventory and send them to other inventories, near or far.^[1][2]
• Place items as blocks, break blocks, drop items into the world, or absorb dropped items. The Breaker Module and Vacuum Module cover the last two.^[1][6]
• Sort items with filters that go beyond simple item matching, or void items you don't want.^[1]
• Move fluids and energy too, for example with the Fluid Module Mk1 and the Energy Distributor Module.^[1][6]

Who it's for

If you want item-handling automation without a separate block for every job, this mod is for you. You swap modules in the same router to change what it does. There are 20 module types, and each has 9 filter slots to control which items it processes.^[1][7]

You can tune a router further. It has 5 upgrade slots, with 8 upgrade types to choose from. Each module also has 4 augment slots.^[7][8]

Smart Filters can go into a module's filter slots in place of regular items. The Bulk Item Filter, for example, can match up to 54 different items. Smart Filter items from FTB Filter System work in module filter slots too. They can't be reconfigured while installed, so keep the filter item in your inventory to change it.^[9][10][11]

Where it fits in the pack

The mod shows up in the automation part of the quest book. The quest "Modular Routers" quest in the processing automation chapter asks you to have a Modular Router plus one of these modules: Energy Distributor Module, Vacuum Module, Fluid Module Mk1, Distributor Module, Activator Module or Breaker Module.^[6]

Modular Routers is a mod for moving items around the world, a bit like a super-configurable hopper. You build one block, plug in modules, and that block pulls, sends, places, breaks or drops things for you. Here's the order I'd tackle it in.^[2]

Step 1: The router itself

The Modular Router is the central block of the whole system. On its own it only acts as a one-slot inventory that hoppers and other piping can feed. To make it useful you install modules, up to nine of them. By default the router ticks once per second and runs every installed module in order.^[4]

Step 2: Blank Module

Nearly every module in this pack is crafted from a Blank Module, so make a few of these first.^[12]

Step 3: Your first working setup

The classic starter is a pull and a send. The Puller Module Mk1 takes items out of an inventory next to the router, and the Sender Module Mk1 pushes items from the router into another inventory.^[2][12]

To aim a module at an inventory, sneak and right-click that inventory with the module. Sneak and right-click a non-inventory block to clear the target.^[13]

If you'd rather clean up an area, the Vacuum Module absorbs dropped items. It also counts for the quest above.^[1][6][12]

Step 4: Configure with filters

Right-click a module in hand to open its GUI. Every module has 9 filter slots, and you can switch between whitelisting and blacklisting there. You can also middle-click an installed module in the router GUI, so you don't have to take it out.^[7]

Once you're sorting lots of items, make a Bulk Item Filter. It matches up to 54 different items, and you can sneak and right-click an inventory to copy its contents into the filter.^[10][12]

Step 5: Upgrades and augments

A router has 5 upgrade slots, and upgrades speed it up or let it handle more items. Upgrades start from a Blank Upgrade.^[4][8][12]

Augments go into modules rather than the router, with 4 augment slots per module. They start from an Augment Core.^[7][12][14]

Recipe id: modularrouters:augment_core

Modular Routers (Modular Routers) is built around one block, the Modular Router. On its own it is just a one-slot inventory. The real work is done by up to nine modules you plug into it, and by upgrades in its 5 upgrade slots. Think of it as a hopper you can reprogram by swapping parts.^{[4][5][8][15]}

The router, its buffer and its tick

• The buffer is a single slot that can hold up to a stack of items. It behaves like a normal inventory, so hoppers and other mods' pipes can put items in and take them out. A comparator placed against the router reads how full the slot is.^[15]
• Each time the router runs, it executes every installed module in turn, from left to right. Module order therefore matters.^[15][16]
• The button at the top right of the router GUI sets redstone control: always run (the default), only run with no signal, only run with a signal, do not run at all, or run once when a redstone pulse arrives.^[15]

By default a router ticks every 20 server ticks, which is once per second, and the pack keeps that value (Router.baseTickRate). Each Speed Upgrade shortens the interval by 2 ticks (Router.ticksPerUpgrade). The floor is 2 ticks, or 10 runs per second (Router.hardMinTickRate).^[16][17]

Eco Mode is an optional switch on the router. If the router does no work for 100 server ticks (5 seconds), it drops into low-power mode and only ticks once every 100 ticks, whatever its Speed Upgrades. As soon as it does any work, it goes back to normal speed. The two timings are Router.ecoTimeout and Router.lowPowerTickRate. It is a good fit for slow jobs, like a Vacuum Module collecting wool from a sheep farm.^[15][17]

Modules and filters

Every module has 9 filter slots, and many have a direction relative to the router's facing. Some also have module-specific settings, and every module has 4 augment slots. Right-click a module in hand to configure it. You can also configure an installed module without removing it, by middle-clicking it in the router GUI or pressing the configure key while hovering over it.^[7]

A module only operates when the item in the router's buffer matches its filter. In whitelist mode, an empty filter never lets the module run. In blacklist mode, an empty filter always lets it run. The filter buttons also control whether item damage, item components such as enchantments, and item tags are taken into account.^[7][13]

Termination is a per-module switch (the T button under the filter slots). When it is on and the module does any work, the router stops for that tick and no modules to its right run. For example, put a Void Module whitelisting Cobblestone before a Sender Module. With Termination on the Void Module, the Sender only runs once the Void Module has nothing left to do, so the Cobblestone is not partly voided and partly sent on.^[18]

Smart filters

Smart filters go in a module's filter slots in place of regular items and match items in cleverer ways.^[9][20]

• Bulk Item Filter: matches up to 54 items. Sneak-right-click an inventory to merge its contents into the filter. Inside an installed module, buttons let you merge or load the targeted inventory's items. It pairs well with a Sender Module for sorting, because the filter remembers what should be in an inventory even after it is emptied.^[10]
• Mod Filter: matches by the mod an item belongs to, with up to 6 mods per filter. Vanilla items count as the mod Minecraft.^[21]
• Regex Filter: matches a regular expression against the part of the registry name after the colon. It holds up to 6 entries and ignores case. One use is a Player Module extracting everything matching _ore from your inventory and sending it home.^[22]
• Inspection Filter: matches integer properties such as fluid or energy level as a percentage, highest enchantment level, durability percentage, or food value. Items without the property return -1, which is different from 0. It is handy for pulling out damaged or discharged items.^[23]
• Tag Filter: the module's own tag-matching button matches anything sharing a tag with a filter item. The Tag Filter is the option for more precise tag matching.^[13]
• FTB Filter System smart filters can also go in module filter slots, but they cannot be configured while installed. You need the item in your inventory to change it.^[11]

Moving items between inventories

Range is where the module tiers differ. These are the values in this pack's config, and they match the mod's own defaults:^[17]

• Sender Module Mk1: 8 blocks, up to 16 with Range Up Augments (Module.sender1BaseRange, Module.sender1MaxRange). The target must sit directly along the X, Y or Z axis with clear line of sight. Glass, fences and iron bars do not block it.^[17][24]
• Sender Module Mk2: 24 blocks, up to 48 (Module.sender2BaseRange, Module.sender2MaxRange). No line of sight is needed. Sneak-right-click the target inventory with the module in hand to set it.^[17][25]
• Sender Module Mk3: can send to any inventory in any dimension, as long as the target is chunk-loaded. The pack's dimension blacklist is empty (Module.dimensionBlacklist). That setting also limits where the Player Module can operate.^[17][26]
• Puller Module Mk1 pulls from the adjacent inventory in its direction. Puller Module Mk2 reaches 12 blocks, up to 24 with Range Up Augments, without line of sight, and is targeted by sneak-right-clicking (Module.puller2BaseRange, Module.puller2MaxRange).^[17][27][28]
• Distributor Module: an extended Sender Mk2 with up to 8 targets. Its strategy is Round Robin, Random, Nearest or Furthest.^[29]
• Player Module: moves items between the router and a player's main inventory, armor, offhand or Ender inventory, from anywhere in any dimension. It is keyed to one player, shown in its tooltip.^[30]

The Vacuum Module scans for dropped items in a 13x13x13 area around the router (6 blocks each way). The pack's base and max range are 6 and 12 (Module.vacuumBaseRange, Module.vacuumMaxRange), so Range Up Augments can grow the area to 25x25x25 and Range Down Augments can shrink it to 3x3x3. With a direction other than All, the area shifts that way.^[17][31]

Working on the world

The Dropper Module drops items with zero velocity, unlike a vanilla dropper. The Flinger Module also gives them a speed, pitch and yaw. The Placer Module places a buffer item as a block next to the router and follows normal placement rules.^[32][33][34]

The Breaker, Placer and Activator modules act as a fake player. By default that is a player named [Modular Routers], but with a Security Upgrade installed they act as the upgrade's owner, which is safer with claim protection. The Breaker takes its harvest level from the pickaxe used to craft it, and the pack keeps that limit switched on (Module.breakerHarvestLevelLimit). A Breaker filter matches the drops by default, not the block itself.^[17][35][36]

The Activator Module uses the buffer item on nearby blocks or entities, with an attack mode. In this pack attack mode costs 150 FE per operation ([[config:config/modularrouters-common.toml#Energy Costs.activatorModuleEnergyCostAttack]]), the same as the mod default. Weapon cooldowns still apply, so extra Speed Upgrades just waste energy and durability.^[17][37]

Extruder Module Mk1 extends and withdraws a row of blocks taken from the router's buffer. By default it extends while the router has a redstone signal and withdraws when it does not. Extruder Mk2 places from a 9-slot template inside the module instead. Its blocks are virtual and drop nothing, so it suits doors and bridges rather than farming. The in-game manual still quotes older ranges (12 to 24 for Mk1, 24 to 48 for Mk2). The pack's config says Mk1 is 16 base and 32 max, and Mk2 is 32 base and 64 max, so go by the config (Module.extruder1BaseRange, Module.extruder1MaxRange, Module.extruder2BaseRange, Module.extruder2MaxRange).^[17][38][39]

Fluids

A router has no internal tank. It handles fluids only through a single fluid container item, such as a bucket, in its buffer. The Fluid Module Mk1 either pulls fluid from the adjacent block into that container, or pushes it out to the world or an adjacent tank. Fluid pipes from other mods can also pump fluid in and out of the container without a Fluid Module. The Fluid Module Mk2 reaches 12 blocks (24 with Range Up Augments) in this pack (Module.fluid2BaseRange, Module.fluid2MaxRange).^[17][41][42]

The router's base fluid rate is 50 mB per tick in each direction (Router.fluidBaseTransferRate). Each Fluid Transfer Upgrade adds 10 mB per tick (Router.mBperFluidUpgade), up to 400 (Router.fluidMaxTransferRate). That means at most 35 Fluid Transfer Upgrades. Speed Upgrades only make transfers happen more often in smaller amounts, not faster overall.^[17][42][43]

Energy

The Energy Upgrade gives the router an internal energy buffer. Each upgrade adds 50,000 FE of capacity and 1,000 FE of transfer per router tick, and this pack uses those values (Router.fePerEnergyUpgrade, Router.feXferPerEnergyUpgrade). A router tick is every 20 server ticks with no Speed Upgrades, so real throughput can be lower than you expect.^[17][44]

The Energy Output Module pushes FE to an adjacent block. The Energy Distributor Module does the same for up to 8 nearby blocks. Both draw from the internal buffer first, or from an energy-holding item in the item buffer. An energy item in the buffer can also be charged from the router, or drained into it, using a switchable button in the router GUI.^[44][45][46]

Modules cost no energy to run in this pack. Every module's cost in the config is 0, except the Activator in attack mode at 150 FE. Costs are configurable, and module tooltips show them where they apply.^[17][44]

Augments

Augments are like upgrades, but they go into a module's 4 augment slots instead of the router. Not every module accepts every augment, and some augments stack.^[7][14]

• Range Up and Range Down: each adds or removes one block of range on any module with a range (Sender Mk1/Mk2, Puller Mk1/Mk2, Extruder Mk1/Mk2, Fluid Mk2, Vacuum).^[47][48]
• Stack Augment: each one doubles the items a module handles per tick, up to the item's natural stack size. A module's Stack Augments override the router's Stack Upgrades.^[49]
• Regulator Augment: adds a numeric limit to the GUI. For senders it caps how many of an item the target holds. For pullers it sets a minimum to leave behind. For fluid modules it can be a percentage of tank capacity or an amount in mB.^[50]
• Redstone Augment: lets a module define its own redstone behaviour, instead of running whenever the router runs.^[51]
• Fast Pickup (Vacuum only) skips the normal pickup delay on dropped items. XP Vacuum (Vacuum only) absorbs experience orbs instead of items and turns them into Bottles o' Enchanting.^[52][53]
• Pickup Delay (Dropper and Flinger) adds 10 ticks of pickup delay per augment. Pushing (Extruders) increases how hard entities are shoved.^[54][55]

A couple of other upgrades are worth knowing. The Muffler Upgrade silences the router: adding more of them disables first the sounds, then the particle effects, then the active animation. The Blast Upgrade makes the router immune to explosions and boss mobs.^[56][57]

Modular Routers progression is one block with a lot of add-ons. The Modular Router is the only block in the mod, modules define what it does, and most modules are crafted starting from a Blank Module.^[5][12][58]

The quest source for this mod shows one quest, in the automation chapter. It's untitled, and it asks you to get a Modular Router plus one of these modules: Energy Distributor Module, Vacuum Module, Fluid Module Mk1, Distributor Module, Activator Module or Breaker Module. See "Modular Routers" quest.^[6]

Module tiers

Most of the progression is upgrading one module into the next. These are the chains in this pack:^[12]

• Sender: Sender Module Mk1 leads to Sender Module Mk2, which leads to Sender Module Mk3. Mk1 has two recipes, and Mk2 and Mk3 each upgrade the tier below.^[12]
• Puller: Puller Module Mk1 upgrades into Puller Module Mk2.^[12]
• Fluid: Fluid Module Mk1 upgrades into Fluid Module Mk2.^[12]
• Distribution: the Distributor Module is built on top of a Sender Module Mk2. Combine it with the Energy Output Module to get the Energy Distributor Module.^[12]
• Dropping: the Dropper Module upgrades into the Flinger Module.^[12]
• Top of the tree: the Player Module needs both a Puller Module Mk2 and a Sender Module Mk3.^[12]

Upgrades

A router has 5 upgrade slots and 8 upgrade types, and each type has its own limit on how many you can install. Upgrades are built from the Blank Upgrade.^[8][12]

• Speed Upgrade: each one cuts the router's tick interval by 2 server ticks, from the default 20 down to a minimum of 2.^[16]
• Stack Upgrade: each one doubles the items a module processes per tick, up to 64 or the item's stack size. 6 is the most useful number to install.^[59]
• Fluid Transfer Upgrade: only affects the two Fluid Modules. It raises the base 50mB/tick rate by 10mB/tick each, up to 400mB/tick, which takes 35 upgrades.^[43]
• Energy Upgrade: gives the router an energy buffer. Each one 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.^[44]
• Security Upgrade: only whitelisted players can open the router. It holds 6 extra players on top of its creator.^[36]
• Blast Upgrade: makes the router immune to explosion damage and to being destroyed by boss mobs.^[56]
• Sync Upgrade: keeps routers with the same tuning value running on the same tick.^[60]
• Muffler Upgrade and Camouflage Upgrade: cosmetic and quality-of-life. Muffling cuts sounds, and with more upgrades particles and the active animation too. Camouflage disguises the router as another block.^[57][61]

Augments and filters

Augments are made from an Augment Core. Some augments only fit certain modules.^{[12][40][52][62]}

4× Augment CoreMod recipe

• Fast Pickup Augment only fits the Vacuum Module, and Mimic Augment only fits the Extruder Module Mk2.^[40][52]
• Redstone Augment fits any module and gives it its own redstone behaviour. Regulator Augment lets you set an item-count limit on a module.^[50][51]

Smart filters can go in any module's filter slots. The Bulk Item Filter is the base for the Inspection Filter, Mod Filter, Regex Filter and Tag Filter.^[12][20]

Modular Routers connects to other mods in this pack in a few ways. An add-on mod provides two items that are built on Modular Routers parts. The pack also adds a recipe that uses one of the router modules. The in-game guide confirms one filter integration as well.^[11][12]

Mekanistic Routers: chemicals

The Mekanistic Routers add-on adds the Chemical Module Mk1 and the Chemical Transfer Upgrade. The module is made from a Blank Module and the upgrade from a Blank Upgrade. Both are shaped crafting recipes that come from the add-on itself, not changes made by the pack.^[12]

A pack-added recipe using the Player Module

The pack adds its own custom machine recipe that takes the Player Module as an input. The other inputs are an Empowered Palis Crystal Block, an Soul Vial and a Book. The recipe block below shows it exactly as it is in the pack.^[12]

FTB Filter System

Because FTB Filter System is installed, its Smart Filter items can go in a module's filter slots and will filter items appropriately. There is one limitation: you can't configure these filters while they are installed in a module, as you can with Modular Routers' own filters. Keep the filter item in your inventory when you need to reconfigure it.^[11]

In this pack, the quest sources show Modular Routers in a single quest, found in the processing automation chapter. There is no longer questline for the mod in the sources here.^[6]

The Modular Router quest

The quest is "Modular Routers" quest, and it has no title in the quest file. It has two item tasks, listed in this order.^[6]

1. Submit a Modular Router.^[6]
2. Submit any one of these modules: Energy Distributor Module, Vacuum Module, Fluid Module Mk1, Distributor Module, Activator Module or Breaker Module.^[6]

The second task accepts a choice of modules, so you only need one of the six to cover it.^[6]

Modular Routers has a lot of options, but only a handful change how your setups behave day to day. Every numeric value in this pack's common config is shown alongside the mod default, and they all match. So the pack hasn't changed any of these numbers, and you get the standard Modular Routers balance.^[17]

Router speed and eco mode

• Router.baseTickRate is 20, so a router runs every 20 server ticks with no upgrades.^[17]
• Router.ticksPerUpgrade is 2, meaning each Speed Upgrade shortens the router's tick interval by 2 ticks.^[17]
• Router.hardMinTickRate is 2, the fastest a router can run no matter how many Speed Upgrades you add.^[17]
• With eco mode on, an idle router drops into low-power mode after Router.ecoTimeout (100) ticks. It then ticks every Router.lowPowerTickRate (100) ticks.^[17]

Energy and fluids

Nearly every module has an energy cost of 0 FE per operation in this pack, for example [[config:config/modularrouters-common.toml#Energy Costs.breakerModuleEnergyCost]] and [[config:config/modularrouters-common.toml#Energy Costs.vacuumModuleEnergyCost]]. The exception is the Activator Module's left-click (attack) operation, which costs 150 FE through [[config:config/modularrouters-common.toml#Energy Costs.activatorModuleEnergyCostAttack]].^[17]

Each Energy Upgrade adds 50,000 FE of capacity (Router.fePerEnergyUpgrade) and 1,000 FE/t of transfer rate (Router.feXferPerEnergyUpgrade).^[17]

For fluids, a router moves 50 mB/t in each direction by default (Router.fluidBaseTransferRate). Each Fluid Transfer Upgrade adds 10 mB/t (Router.mBperFluidUpgade), up to a cap of 400 mB/t (Router.fluidMaxTransferRate).^[17]

Module ranges

Base range is what you get with no range upgrades, and max range is the cap. Here is what this pack uses:^[17]

• Sender Mk1: 8 base, 16 max (Module.sender1BaseRange, Module.sender1MaxRange).^[17]
• Sender Mk2: 24 base, 48 max (Module.sender2BaseRange, Module.sender2MaxRange).^[17]
• Extruder Mk1: 16 base, 32 max (Module.extruder1BaseRange, Module.extruder1MaxRange).^[17]
• Extruder Mk2: 32 base, 64 max (Module.extruder2BaseRange, Module.extruder2MaxRange).^[17]
• Fluid Mk2 and Puller Mk2: 12 base, 24 max each (for example Module.fluid2BaseRange and Module.puller2MaxRange).^[17]
• Vacuum: 6 base, 12 max (Module.vacuumBaseRange, Module.vacuumMaxRange).^[17]

Breaking, blacklists and XP

Module.dimensionBlacklist is an empty list here, so no dimensions are blocked for the Sender Mk3 or the Player Module. Router.blockBreakXPDrops is true, so block-breaking modules drop XP where appropriate, such as when mining ores.^[17]

Client options

In the client config, Misc.alwaysShowSettings is true, so module tooltips show their settings without you holding Shift. Misc.heldRouterShowsCamoRouters is also true, so holding an Item Router highlights nearby camouflaged routers.^[63]

FTB StoneBlock 4 1.21.0 ships Modular Routers 13.2.7. Below are the notable changes from the mod's own changelogs for 13.2.3, 13.2.4, 13.2.5 and 13.2.7, newest first, so you can see what has already been fixed in the version you're playing.^{[3][64][65][66]}

13.2.7

• Fixed an item duping issue when routers containing items are assembled or disassembled to or from a Sable sublevel.^[67]

13.2.5

• Fixed the router GUI going blank if the router blockstate changed (for example active to inactive) while the GUI was open.^[66]
• Fixed the Distributor Module in pull mode not pulling from inventories with oversized itemstacks, such as Functional Storage drawers where stacks can go way over 64 items.^[66]
• Fixed the Fluid Module not transferring correctly from fluid handlers with multiple tanks when a filter is used.^[66]
• Added the modularrouters:player_module_blacklist item tag, which stops certain items being handled by the Player Module. It contains no items by default.^[66]

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 warns can be a server-killer.^[65]
• Updated to work with the current release of FTB Filter System (21.1.4).^[65]
• Fixed items sometimes getting lost when clicking in filter screens.^[65]

13.2.3

• The Activator Module is now 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.^[64]
• Fixed the Sync Upgrade kicking players when given a tuning value of 0. Accepted values are now correctly 0..19, not 1..20.^[64]
• Fixed a dupe issue with Regulator Augments.^[64]
• Fixed the module GUI allowing too many augments, and the router GUI allowing too many upgrades, into their slots.^[64]
• Fixed filter item data sometimes getting lost during GUI edits when other settings were changed.^[64]
• Fixed module settings sometimes getting lost for the Sender Mk3 when the target was not chunkloaded.^[64]
• Fixed scroll wheel behaviour on float-value textfields, such as the flinger module settings.^[64]
