What is PolyLib?

Same as in the All the Mods 10 8.1 guide

PolyLib is included in this pack at version 2100.1.0, shipped as a NeoForge jar.[1]

It has been part of the pack since version 2.25 or earlier, so it is not a recent addition.[1]

How do you get started with PolyLib?

Same as in the FTB Skies 2 1.22.0 guide

There is nothing to craft or unlock to get started with PolyLib. The only thing the pack gives us for this mod is a single setting, so your first step is simply knowing what it does.[2]

The setting is serverOnlySupport, and this pack has it set to false. When it is on, PolyLib can run as server side only support. When it is off, as it is here, non-vanilla clients without PolyLib may not be able to connect.[2]

Tip: If you host a server for friends, leave serverOnlySupport at the pack's value of false, and make sure everyone joins with the pack installed. That avoids the connection problem the setting describes for clients without PolyLib.[2]

Unverified No first items, recipes or in-game steps for PolyLib could be confirmed from the available sources, so none are listed here. This site does hold FTB StoneBlock 4's own recipes, read from the pack itself: look the item up in the item browser.

How does PolyLib work?

1 part

Same as in the FTB Skies 2 1.22.0 guide

There isn't much to dig into here. The only thing the sources document for PolyLib in this pack is a single config option. Nothing in them describes machines, multiblocks, power, fluid or item handling, or automation for this mod.[2]

Server-only support

The one setting is serverOnlySupport. In this pack it is set to false. When it is turned on, PolyLib can run as server-side-only support. With it off, as it is in this pack, non-vanilla clients that don't have PolyLib installed may not be able to connect.[2]

Tip: If you play on a server with this pack, install the full pack on your client rather than relying on a partial setup. With the option left at false, a non-vanilla client without PolyLib may be refused a connection.[2]

Unverified No sources describe any machines, multiblocks, power or fluid systems, or automation behaviour for PolyLib, so none are covered here.

Which PolyLib config options matter?

1 part

Same as in the FTB Skies 2 1.22.0 guide

PolyLib is a library mod, and the pack's config for it is tiny. The file config/polylib.json has just one option, so there isn't much to tweak.[2]

serverOnlySupport

The pack sets serverOnlySupport to false. The option's own description says it allows PolyLib to run as server-side-only support. It also says that without it, non-vanilla clients that don't have PolyLib may not be able to connect.[2]

Tip: If you run a server for this pack, keep that description in mind. With the option at false, players should join with the pack installed rather than a partial set of mods, because clients without PolyLib may fail to connect.[2]

Unverified The sources don't say what PolyLib's default for serverOnlySupport is, so it's unconfirmed whether the pack changed this value from the mod default.

Items and blocks

We can't match this mod to the pack's item list: it registers as polylib, and the pack's recipe dump has nothing under that name. That means we found nothing, not that the mod adds nothing. Search the item browser
