Fantasy Technology (AE: 幻梦编码) adds a compact, ME-native crafting pipeline to Applied Energistics 2 for NeoForge 1.21.1: a Blank Fantasy Pattern (空白幻梦样板) that the Fantasy Encoding Terminal (幻梦编码终端) turns into a Fantasy Recombination Pattern (幻梦重组样板) storing a processing recipe as data, and a Fantasy Molecular Reconfiguration Pattern Provider (幻梦分子重构演算样板供应器) block that executes them instantly — consuming the ingredients from your ME network and injecting the results back, with no intermediate machine in between.
- Blank fantasy patterns (
ae2:blank_pattern+ amethyst shard) are consumed by the encoding terminal; the encoded recombination pattern carries the recipe as data: up to 81 ingredient entries and 6 results, items, fluids and (with Mekanism) chemicals alike. - Ingredient slots can be tag-based: a bookshelf pattern asks for any plank (
#minecraft:planks) instead of one specific wood, so the crafting planner picks whatever your network actually has. - Same-kind entries merge on encoding — six planks + three books encode as one
6x planks+ one3x bookentry. - Patterns are fully persistent: crafting jobs survive world reloads.
- Fantasy patterns (blank or encoded) cannot be placed into AE2's own pattern providers — they only run in the Fantasy Molecular Reconfiguration Pattern Provider.
- An ME terminal part (attach it to your network like any terminal) with the full network item list on the side.
- Transfer any JEI recipe into the encoding grid with one click — smelting, stonecutting, and modded machine categories work, not just vanilla crafting. Amounts always come from what JEI shows (so machine mods such as Modern Industrialization transfer correct counts), and tags are restored from the server-side recipe.
- Result slots are free ghost slots; ingredients are preview-only so tags are never lost.
- An ME crafting device that holds Fantasy Patterns and registers them with the network's crafting service.
- When a crafting CPU executes a pattern, the block consumes the ingredients and inserts the results into the network instantly — no progress bar, never busy, so a single block can process as many crafts per tick as the CPU requests.
| Dependency | Required | Notes |
|---|---|---|
| Minecraft 1.21.1 | ✅ | |
| NeoForge 21.1.x | ✅ | |
| Applied Energistics 2 | ✅ | 19.2.x |
| JEI | ✅ | Required — recipe transfer into the encoding terminal |
| Mekanism | 🔶 Optional | Chemical inputs/outputs in patterns |
| Applied Mekanistics | 🔶 Optional | Bridges chemicals into AE2 |
Without Mekanism/Applied Mekanistics the mod runs fine; chemical slots simply aren't available.
- Craft a Blank Fantasy Pattern (
ae2:blank_pattern+ amethyst shard) and place it in the Fantasy Encoding Terminal. - Open a recipe in JEI and press the transfer button (the
+) — inputs and results are filled in, tags and amounts preserved. - Optionally press the double button next to the results to scale the recipe up.
- Press Encode — the blank fantasy pattern becomes an encoded Fantasy Recombination Pattern.
- Place encoded patterns in a Fantasy Molecular Reconfiguration Pattern Provider block connected to your ME network. Request the pattern's output from any terminal: the block consumes the ingredients and produces the result instantly.
Tip: hovering an encoded pattern in your inventory shows its full recipe (ingredients and results) in the tooltip.
- Fast crafting plans (adapted from OmniSequence-Transfinite, MIT): with a Fantasy Molecular Reconfiguration Pattern Provider on the network, crafting calculations run through an aggregated recipe-tree planner — deep recursive trees (e.g. Mystical Agriculture's layered essence chains) are deduplicated into a graph and evaluated in one linear pass, and recipes that borrow a tool or container instead of consuming it take a specialized path (one tool borrowed, worn remains recycled). Anything the planner cannot prove equivalent is handed straight back to AE2, either as a single subtree or by abandoning the aggregate before any work has been delegated.
- Batch dispatch: the same provider accepts several repetitions of one recipe in a single push, so a crafting CPU does one inventory walk instead of N. Throughput is deliberately unchanged — each craft still costs the CPU one operation, so co-processor scaling behaves exactly as it does in stock AE2.
- Both are server config options in
fantasy_technology-server.toml(max_fast_mode,batch_dispatch_enabled);diagnosticslogs why the planner aggregated or fell back. License notice: THIRD_PARTY_NOTICES.md. - Coexistence with OmniSequence-Transfinite: when OmniSequence is installed,
FantasyTechnologyMixinPluginskips this mod's batch dispatch and its pattern-input cache, both of which OmniSequence already provides — chaining two extraction wrappers would otherwise scale one recipe twice. The aggregated planner stays active either way: it triggers on this mod's block, OmniSequence's triggers on theirs, and the two wrappers nest correctly. - Modern Industrialization & other machine mods: recipe transfer uses the amounts JEI displays, so multi-count machine recipes (e.g.
2x iron plate) fill in correctly. - AllTheLeaks: if a mod's
getIngredients()has side effects that AllTheLeaks locks against, the server falls back to the displayed recipe instead of failing — the first occurrence logs a warning, and that recipe type is remembered for the session. - JEI tag-information pages (
minecraft:tag_recipes/*) and the P2P tunnel attunement page (from the AE2-JEI-Integration addon) are intentionally blocked from transfer — browse-only pages, not recipes.
