Nether roof height decreaser

Nether Roof Carver Turns the Nether into a world with a single fake roof. A flat bedrock layer at y80 acts as the ceiling, and the vanilla roof is gone. Above it is a huge open space from y81 to the height limit, clear of terrain, lava and trees, for farms and big builds. Below y80 the Nether is vanilla and nothing get replaced Portals that generate on the roof are broken, and you're moved below it, with a new portal built beside you. No experimental toggles needed.

NOTE it won't ruin your builds if you reload or rejoin your world it only replace stuff with air of unloaded chunks , new chunks , and WONT replace old chunks or already loaded or refreshed or whatever you call it

BUT it might ruin your past build if u have builds from y80 above so I SUGGEST you to be cautious about this but whoever builds up there tho?

The mod might ruin it or delete it but u can also build a new one up there and it might be better honestly

The trade-off is there and it's your decision
