About Seamless Ores

From Modrinth

Universal ore variants for vanilla and modded stones, so every ore blends into the stone it generates in. Supports vanilla and modded ores, keeps the same veins and drops, and works with Terralith, JEI, REI, and Jade.

Seamless Ores Vanilla Variants Preview

Seamless Ores adds ore variants for the stones ore generates in, such as granite, andesite, tuff and dripstone, and the stones other mods add. Each variant uses its stone as the background, so the ore matches the wall it sits in.

The amount of ore in the Overworld stays almost exactly the same, because the veins are the same and in the same places; only their look changes. The few settings that do change the amount are listed below, and each has its own switch.

Resource pack

Seamless Glowing Ores is the companion resource pack. Ores glow in the dark, with an optional connected outline that joins ore of the same type across different stones, with animated and subtle versions. It needs only Fusion.

Stones

Ore gets a variant in granite, diorite, andesite, tuff and dripstone, and gold and quartz in basalt and blackstone in the Nether. The Sulfur Caves' cinnabar holds ores too, on Minecraft 26.2 and 26.3, and on 1.21.1 and 1.20.1 with Vanilla Backport. The deep blackstone that Terralith lays in its caves gets matching ore on every version.

Stones from other mods are covered as well, each with the vanilla and modded ores that really form inside it:

> Blockus, Born in Chaos, Create, Create: TFMG, Forbidden and Arcanus, Let's Do Meadow, Mythic Upgrades, Promenade, Spawn, Twigs and Wilder Wild.

Calcite and smooth basalt get ore only where Create's stone layers place them.

Ores from other mods

The ores of these mods get variants in the stones they generate in:

> Cobblemon, Create, Create: New Age, Create: TFMG, Dense Mekanism, Energized Power, Exp Ores, Extreme Reactors, Ice and Fire (Community Edition), Immersive Engineering, Malum, Mekanism, Modern Industrialization, Mystical Agriculture, Mythic Metals, Mythic Upgrades, Occultism, Oreganized, Powah, Silent Gear, Silent's Gems, Tech Reborn and Things.

Not every mod has a build for every Minecraft version and loader, so the blocks you get depend on what you have installed. A modded block exists only when the mods it belongs to are installed, so there is nothing to configure. The variants carry the same tags, drops, experience, hardness and mining level as the ore they replace, so JEI, REI, Jade, ore doubling and processing chains treat them as ordinary ore.

Amount of ore

A block that becomes granite iron ore was already going to be iron ore, and a vein running from stone into granite changes look block by block. These settings are the exceptions:

  • Copper. Vanilla's large copper veins and dripstone caves look like solid copper once the

stone around the ore matches, so ordinary copper defaults to 75 percent and dripstone caves to 50 percent. Set both to 100 for vanilla amounts.

  • Lush Caves. Ore left bare in their clay and moss becomes clay or moss. This removes a little

ore, only there.

  • Sulfur Caves (26.2 and 26.3, and 1.21.1 and 1.20.1 with Vanilla Backport). No ore sits in or

against their sulfur and cinnabar. This removes ore, only there.

  • Cinnabar ores (the same versions). Gold, iron, redstone and the modded ores that occur beside

cinnabar form inside it, in the same veins and at the same rates as the ore they stand in for. This adds ore, only in cinnabar, with a slider for how much.

  • Geology, off by default. When on, ore stops forming in the vanilla stones it could never form

in, such as coal in granite. This removes ore. Ores in other mods' stones always follow a fixed version of this rule, and Cobblemon's evolution stones keep only the stones that fit their lore (with Geology on, in the vanilla stones as well, on 1.21.1 and 1.20.1).

The Nether

Vanilla gold and quartz only generate in netherrack, so their basalt and blackstone versions are new ore rather than a restyle. They are on by default, and the same goes for the Nether ores of the supported mods. Nether ore rarity (one in two by default) and Nether vein size (80 percent by default) control how much of it forms, and turning basalt and blackstone off brings Nether generation back to vanilla. Bastions are protected, so their walls never turn into ore.

Compatibility

Worldgen overhauls and ore distribution datapacks keep their own settings, including Terralith, because existing ore features are extended rather than replaced.

Settings

The settings screen opens from Mod Menu on Fabric, or from the mods list on NeoForge and Forge. Every stone can be switched off and each supported mod has its own section; sections for mods you do not have are hidden. Settings never change which blocks exist, only what generates, so a client and a server with different settings always agree. Changes apply to newly generated chunks.
