Spectrum Compat

A compatibility mod that bridges Spectrum with The Aether, Deep Aether, VanillaBackport, Copper Age Backport and Better Archeology.

How it works

Heads are real registered block-items tagged into #c:skulls, plus per-mob loot-modifier and recipe entries that plug into Spectrum's existing systems. A small set of mixins covers the cases where data alone isn't enough. Every integration is gated by mod-loaded conditions, so any combination of optional mods works out of the box.

Textures are referenced from the source mods' jars at runtime; this mod ships zero texture bytes (required by The Aether's license).

Supported mods

Mod What's added The Aether 19 mob heads (incl. 3 Moa colours), anvil-crushing dye recipes for Aether flowers Deep Aether 11 mob heads (incl. 7 Quail variants), anvil-crushing dye recipes for DA flowers VanillaBackport Happy Ghast head, warm/cold Chicken/Cow/Pig heads (memory variant-lock), anvil-crushing dyes for VB flowers Copper Age Backport 8 Copper Golem heads (4 oxidation × waxed/unwaxed), honeycomb wax recipes Better Archeology Enchanter recipes for penetrating_strike, tunneling, soaring_winds; disarming exclusive-set

Variant heads (Moa, Quail, Copper Golem, Chicken/Cow/Pig) are NBT-filtered, so the right variant drops from the right kill rather than rolling randomly.

A few mobs are deliberately skipped because they're either unkillable upstream (Whirlwinds, Gentle Wind, Slider, Creaking) or practically unreachable in survival (Windflies — no biome spawner entries). Bosses are excluded by Spectrum's own #c:bosses blacklist chain.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.226+
• Spectrum 1.11+
• Any combination of the optional source mods listed above
