[Bug Report]: Ancient Debris is much rarer in `jamd:nether` dimension versus vanilla `minecraft:the_nether`

[James103]

Modpack Version

1.27.0

Describe your issue.

From my experience, Ancient Debris is much rarer in Just Another Mining Dimension's nether versus the vanilla nether dimension, despite there being many more netherrack blocks for ancient debris to generate in.

In my world, as of the time of writing, there were an estimated 1,112 ancient debris within 4,321 chunks of jamd:nether, while there were an estimated 16,686 ancient debris within 16,919 chunks of minecraft:the_nether.
This corresponds to an estimated 0.25 ancient debris per chunk of jamd:nether versus 1.0 ancient debris per chunk of minecraft:the_nether.

This ore feature specification generates only 0-1 blocks of ancient debris per vein despite an ore_size of 3, leading to ancient debris being rarer in jamd:nether:

Craftoria/config/jamd/nether.json

Lines 202 to 236 in dc57471

	{
	"ore_size": 3,
	"discard_on_air_chance": 1.0,
	"modifiers": [
	{
	"type": "minecraft:in_square"
	},
	{
	"height": {
	"min_inclusive": {
	"absolute": 8
	},
	"max_inclusive": {
	"absolute": 24
	},
	"type": "minecraft:trapezoid"
	},
	"type": "minecraft:height_range"
	},
	{
	"type": "minecraft:biome"
	}
	],
	"targets": [
	{
	"target": {
	"tag": "minecraft:base_stone_nether",
	"predicate_type": "minecraft:tag_match"
	},
	"state": {
	"Name": "minecraft:ancient_debris"
	}
	}
	]
	},

Furthermore, the other ancient debris ore feature definition has an ore_size of 2 and never generates any ancient debris:

Craftoria/config/jamd/nether.json

Lines 237 to 271 in dc57471

	{
	"ore_size": 2,
	"discard_on_air_chance": 1.0,
	"modifiers": [
	{
	"type": "minecraft:in_square"
	},
	{
	"height": {
	"min_inclusive": {
	"above_bottom": 8
	},
	"max_inclusive": {
	"below_top": 8
	},
	"type": "minecraft:uniform"
	},
	"type": "minecraft:height_range"
	},
	{
	"type": "minecraft:biome"
	}
	],
	"targets": [
	{
	"target": {
	"tag": "minecraft:base_stone_nether",
	"predicate_type": "minecraft:tag_match"
	},
	"state": {
	"Name": "minecraft:ancient_debris"
	}
	}
	]
	},

this is specifically because jamd is using the wrong feature type (ore blobs rather than scatter ores, using the minecraft wiki terms), unfortunately. someone will need to balance all the ScatteredOre features, which generate in a very different way.

I would also be interested in the total non-netherrack distribution at 8 to 24 in vanilla vs jamd nether.

Hmm... tempted to call this a feature—even if it's a "bug" that made it happen—ancient debris really shouldn't be easier to mine than it is in the Nether.

(JAMD Nether is much easier to travel than the proper Nether, yes? I've not actually been to JAMD's Nether mining dim.)

[Linguardium]

who navigates the mining dimension or the nether to find ore? dont people just use rftools builders / mech miners / whatever else (turtles?)

[SubordinalBlue]

Point taken, but also "I do that". At least for jamming for AD/netherite early. Mining gadget and a diving rod make it easy to find, without removing the fun/challenge of travel in the nether.

I mean, the challenges for an early game and/or new players shouldn't be too flattened for the convenience of later stages. (And there's just flat out generating one's own AD instead automining ores in the terrain)
