Seamless Ores

Seamless Ores 5.1.0 adds deep blackstone, Vanilla Backport's Sulfur Caves and cinnabar, Born in Chaos, Ice and Fire Community Edition and Promenade on more versions, and a switch for the chat note.

Deep blackstone

• Terralith lays blackstone deep in its thermal and mantle caves, and the game's ore lands in it there. That ore now matches the blackstone, on every version, with Terralith as a mod or as a datapack.
• Ore that Terralith's caves wall in (the large iron veins among them) is restyled at the end of each chunk, so it no longer shows as tuff or deepslate ore inside blackstone. In a test area of 441 chunks on 1.21.1, walled-in ore went from 1,607 blocks to 91.
• It follows the fixed geology rule, like every stone another mod places.

Vanilla Backport (1.21.1 and 1.20.1)

• The Sulfur Caves stay bare, as on 26.2 and 26.3: no ore in or against their sulfur and cinnabar, the large copper and iron veins included. In 49 test chunks, ore touching sulfur or cinnabar went from 323 to 0 on 1.21.1 and from 589 to 0 on 1.20.1. This removes a little ore, and has its own switch.
• Cinnabar ores: gold, iron and redstone, plus the silver, lead, antimony and sulfide ores of Create, Tech Reborn, Occultism, Silent Gear, Immersive Engineering, Mekanism, Dense Mekanism, Modern Industrialization, Oreganized, Ice and Fire Community Edition, Mythic Metals and Create: The Factory Must Grow where those are installed, in the same veins as their originals. A new Sulfur Caves config tab has the switch and an amount slider. They exist only with Vanilla Backport installed.

Born in Chaos (1.21.1 NeoForge, 1.20.1 Forge)

Its black argillite now holds ore that matches it, under the fixed geology rule.

Ice and Fire Community Edition

• New silver and sapphire art, drawn from the Community Edition's own textures, on every version, and deepslate silver gets art of its own.
• Now on 1.21.1 NeoForge, 1.20.1 Fabric and 26.1.2 NeoForge as well as 1.20.1 Forge. On 26.1.2 it supports the Community Edition's current beta build, its only build there.

Promenade

Asphalt and blunite on 26.3 NeoForge, and on 1.21.1 Fabric and NeoForge, Promenade's first builds there.

Cobblemon

The evolution stone ores in other mods' stones now follow the geology rule too, by lore: each stone keeps only the rock it belongs in (fire stone in volcanic rock, water stone in limestone and marble, moon and sun stone where their real feldspars form, and so on). This removes evolution stone ore from the stones it does not fit.

With the Geology option on (off by default), the same lore also applies in the game's own granite, diorite, andesite and tuff, on 1.21.1 and 1.20.1.

Chat note

The one-time note in chat can be turned off in the config (Client tab, 26.x). A modpack can also ship config/seamlessores-note.txt to skip it.
