Hello, I have created a data pack for my own modpack from TFC.
I would like to ask for information about what values can be used in the section - placement
specifically salt, separation, spacing, prioryty.
I would be grateful if you could indicate the ranges or specific values that can be used.

`
{
"type": "createoreexcavation:vein",
"amountMax": 25.0,
"amountMin": 8.0,
"biomeWhitelist": "tfc:is_vein",
"icon": {
"item": "tfc:ore/small_native_copper"
},
"name": "{"translate":"Stannite vein"}",
"placement": {
"salt": 2078084124,
"separation": 8,
"spacing": 128
},
"priority": 0
}

`

It works like the vanilla structure placement with a random_spread type. See the Minecraft Wiki
