Configurable Cobblestone Generator
by Luc1fer1o
Configurable Cobblestone Generator lets a server owner decide what lava and water cobblestone generators produce, using weighted block outputs.
What it does
Vanilla lava-water cobblestone generation is replaced by a configurable system where each result carries a relative weight. Rare outputs stay rare and common outputs stay common. Entries can name any registered block id, including blocks added by other installed mods. With the default setting, minecraft:cobblestone carries weight 100, so the behavior matches vanilla until the server config is changed.
The generation settings sit in a server config file with a generation section, where an enabled flag turns the custom behavior off. Invalid or empty entries fall back safely to cobblestone. The mod suits skyblock packs and progression packs that need custom resource generation. Without Create the mod works normally.
Installation is on the server only, so players join without installing it. The mod is built for NeoForge 1.21.1, with one file published: 1.0.0 for 1.21.1, dated 2026-06-28. The code is under All rights reserved and is not open source.
Key features
Weighted generator outputs
Each result in generatedBlocks has a relative weight, so the most common result can be cobblestone and an iron ore can appear far less often.
Vanilla default preserved
The default entry keeps minecraft:cobblestone at weight 100, so a fresh config reproduces vanilla cobblestone.
Any registered block
Outputs can use any registered block id, including ores and blocks from other mods.
Optional Create drill support
Create's drill-based cobblegen setups use the same weighted outputs when Create is present.
