Create ReAutomated: Traces

When a freshly generated chunk contains an Ore Node, Traces stamps a small flat patch of surface stone above it. Each trace takes its base from the stone the node sits in, so it shows cobblestone or deepslate variants as they occur below, topped with a small accent block whose type the server can set.

The mod works with NeoForge 1.21.1 and requires Create and Create ReAutomated. It also works with Ore Nodes, and any node registered by another mod is handled, since the mod does not depend on a specific node. Trace placement is wired into the biome tag createreautomatedtraces:has_traces, which covers the overworld and the nether by default. Modded biomes and custom dimensions can be added through a datapack that extends that tag. Detection only runs on freshly generated chunks, so existing worlds are not retrofitted and nodes placed later by hand or by commands do not trigger a trace.
