Import or force block+item IDs from another map?

[Geethebluesky]

Is there currently any way to tell Forge "use the same block IDs and item IDs used for this other map, with this new one"?

 

Or to import/export lists of IDs and tell Forge which ones to use, or anything that would accomplish a similar goal? This would be within the same MC version (1.12.2).

Probably not. You should never touch IDs.

[Geethebluesky]

Touching IDs in this case would enable importing a schematic made in one map, with modded items, into a new map with the same mods.

you dont need that if the registry names are the same you can do it
