Beginner's Guide to Modpacks

What Is a Modpack? — And Why Start Here

A modpack is a curated bundle of mods *pre-configured to work together without conflicts*. Installing mods one-by-one often ends in "versions of mod A and mod B don't match, game won't even launch" — modpacks ship with that compatibility work already done, making them *much safer for beginners*.

Most popular modpacks also include quest books or guided progression, so the "now what?" feeling is reduced. If vanilla Minecraft is "a sandbox you figure out yourself," a modpack is closer to "a 100-hour curated campaign."

Picking Your First Modpack

The [modpack list](/en/modpacks/) covers 12 popular packs. For first-timers, consider:

Open-ended, any genre — [All The Mods 10](/en/info/atm10-complete-guide/) — kitchen-sink with no fixed path.

Pokémon fan — [COBBLEVERSE](/en/info/cobbleverse-complete-guide/) — authentic Pokémon RPG on Cobblemon.

Want brutal survival — [RLCraft](/en/info/rlcraft-complete-guide/). Surviving night 1 *is* the game.

Build crafting — [Cisco's Fantasy Medieval RPG](/en/info/ciscos-fantasy-medieval-rpg-complete-guide/) — 588-node passive skill tree.

What matters most is *what appeals to you*. A pack someone else loves may not click for you, and you'll quit in 30 minutes.

How to Install — 3 Launchers Compared

Modpacks require a dedicated launcher. The vanilla Minecraft launcher does not handle them.

1. CurseForge App (Overwolf launcher) — most beginner-friendly

Largest catalog, search-and-install in one click.

Downside: the Overwolf daemon stays in the background, using a bit of RAM.

Download:

2. Prism Launcher — lightweight + powerful

Open-source successor to MultiMC. Simple UI, strong instance management.

Pulls modpacks from CurseForge, Modrinth, and FTB.

Per-instance Java version, so you can run 1.7.10 through 1.21 from one launcher.

Download:

3. ATLauncher — clean and simple

Supports CurseForge and FTB. Clean UI.

Download:

For first-timers, start with the CurseForge App. Many users move to Prism Launcher after getting comfortable.

First Playthrough — 5 things to know

1. Memorize JEI / EMI shortcuts

These are essential tools shipped with nearly every modpack.

R: Crafting recipe for the item under the cursor

U: Where this item is *used* (reverse lookup)

Search box accepts partial keywords ("iron" → all iron-related items)

Knowing these two keys removes 90% of the "where does this come from?" frustration.

2. Open the Quest Book — F key or main menu

Progression packs (Prominence II, FTB StoneBlock, etc.) include FTB Quests or Heracles Quests. Open via the book icon next to your hotbar or the inventory menu — *what to do next* and *rewards* are laid out step-by-step.

3. Back up. Seriously.

Modpacks are *much* less stable than vanilla. Late-game disk-data corruption is occasionally reported.

CurseForge App: right-click instance → "Open Folder" → zip the world folder

Prism Launcher: right-click instance → "Export Instance"

Once a week, or before any major progression step, is enough.

4. Hold off on shaders

Iris/Optifine + shader combos look amazing, but if you keep them on for the first 60 hours, FPS will tank as your automation lines grow. *Plain visuals for the first 100 hours, then add shaders* is the safe path.

5. Don't go all-in on day one

The most common beginner mistake: "I'll reach fusion power today!" Most modpacks are 100-hour content. *Today: just mining. Tomorrow: first power generator.* Smaller chunks make the experience much more enjoyable.

Performance Basics — 4 quick wins

Full guide at [Performance Optimization](/guides/performance-optimization/). Just the essentials here:

RAM Allocation

6GB: small packs (~150 mods)

8GB: most popular packs

10–12GB: large packs (ATM10, FTB StoneBlock 4) in the late game

Caution: allocating more than 60% of total system RAM slows your OS, which backfires.

Render Distance / Simulation Distance

Start at render distance 12, simulation distance 8.

*Simulation distance* is heavier — pushing it to 16 explodes mob/item processing load.

Java 21 (1.21+ packs) / Java 17 (1.20.1)

1.21 NeoForge: Java 21 required

1.20.1: Java 17

CurseForge App handles this automatically; Prism Launcher requires manual install and assignment.

Sodium / Embeddium-class optimization mods

Most popular modpacks already include them. Only relevant if you're adding standalone mods yourself.
