What is FTB Essentials?
Same as in the All the Mods 10: To the Sky 2.0.6 guide
This pack includes FTB Essentials at version 2101.1.10, shipped as the NeoForge jar ftb-essentials-neoforge-2101.1.10.jar.[1]
It is not a recent addition: the mod was first included in version 1.0 of the pack or earlier, so it has been part of the pack for a long time.[1]
Unverified The sources available here do not describe what FTB Essentials does. No platform page or in-jar guidebook was found for it, so this guide does not list its features, commands or config options.
How does FTB Essentials work?
1 part
Same as in the All the Mods 10 8.2 guide
The sources for FTB Essentials only show a pair of data files that ship in the mod's own jar, both named "ignore_rtp". They are tag files, one for biomes and one for blocks. Nothing here explains machines, multiblocks, power, fluids or item automation, so this section stays short.[2][3]
The ignore_rtp tags
The biome tag has a single entry: the vanilla ocean biome tag (#minecraft:is_ocean).[2]
The block tag lists the vanilla leaves tag (#minecraft:leaves) and bedrock (minecraft:bedrock).[3]
How do you progress through FTB Essentials?
1 part
Same as in the All the Mods 10: To the Sky 2.0.6 guide
Unverified The sources here do not show any quests, tiers or crafting recipes for FTB Essentials in this pack, so there is no progression path to lay out. Check the pack's quest book and the mod's config files for anything beyond this.
What the mod's data files do show
The mod ships a pair of small data tags, both named ignore_rtp. The biome version lists everything in the minecraft:is_ocean tag. The block version lists everything in the minecraft:leaves tag, plus minecraft:bedrock.[4][5]
Both tags have replace set to false, so they add to any existing entries instead of overwriting them.[4][5]
