Which Productive Metalworks config options matter?

4 parts

Same as in the FTB Skies 2 1.22.0 guide

Productive Metalworks keeps its foundry settings in one file, config/productivemetalworks-common.toml. Exactly one value in it is marked as changed from the mod default by this pack, and it's the one you'll notice most when building a foundry.[1]

The value this pack changed

foundryMaxVolume is set to 200 in this pack, while the mod default is 1024. This caps the internal volume of the foundry multiblock, so your foundry can be much smaller than the mod normally allows. Plan your build around that limit.[1]

Tip: If your foundry won't form, check the internal volume first. This pack's limit of 200 is well below the mod default of 1024, so a build that works in another pack may be too big here.[1]

Size and capacity limits

These are the same as the mod defaults, so only the volume cap differs from a standard install.[1]

Casting and fluid behavior

  • foundryCoolingModifier is 4, the same as the mod default. The cooling time of a cast item is the number of mb used in the recipe divided by this number.[1]
  • foundryTankTickRate is 21, the same as the mod default. It sets how many ticks pass between attempts at sharing fluid with tanks below the foundry.[1]

Foundry toggles

The on/off options are all set to true in this pack. An active foundry collects items dropped inside it (foundryCollectItems), damages entities inside it (foundryDamageEntities) and renders its inventory inside the multiblock (foundryRenderInventory).[1]

Watch out: Because entity damage is on, don't stand inside an active foundry. Item collection is on too, so items dropped inside it get collected.[1]
