Spectrum Compat
by MWojt
Spectrum Compat is a NeoForge bridge that connects the Spectrum magic mod with several optional mods, adding mechanics and drops that Spectrum does not provide on its own.
What it does
The mod integrates Spectrum mechanics with other mods. It works as a compatibility layer and adds no gameplay systems of its own, so the features it provides exist only when one of the optional source mods is installed alongside Spectrum. Spectrum is required, and the mod targets Minecraft 1.21.1 on NeoForge.
Optional partners are Aether, Deep Aether, Vanilla Backport, Copper Age Backport and Better Archeology. Each integration is gated on whether its source mod is loaded, so a combination works without the others. The mod ships no texture files; it references textures from the source mod jars at runtime, which keeps the Aether license terms out of its own distribution. Both the server and every player need the mod. It is released under the MIT License and is open source.
Key features
Variant mob heads
Moa, Quail, Copper Golem and Chicken, Cow and Pig variant heads drop from the matching mob, filtered by NBT so the right variant drops.
Per-kill loot entries
Drops come from a loot-modifier recipe entry for each mob, so a head drops on the kill rather than through a random roll.
Heads as tagged items
Heads are registered block-items tagged as c:skulls, so other mods and Spectrum's own systems can recognize them.
Mixins for edge cases
A small set of mixins covers cases where data alone is not enough, while most integration uses data files.
Boss and mob exclusions
Bosses are excluded through Spectrum's own c:bosses blacklist chain, and a few mobs are skipped because they are unkillable upstream or practically unreachable in survival.
