The experience of the Nether dimension with fantasy looks on the outside. A living dimension full of swirls and cyclope like piglins. In a nether dungeon, you will face the "Golden Golem". Watch as ninjas shoot fireballs from nether fortresses. And a dark nether biome (that does not currently exist in this modification yet) where you see the darkest fearing creatures of the game.
I also was trying to make it s that when an iron sword has sharpness level: 4, it turns into a katana. I also did it to the netherite sword as well. But perhaps I am not doing it right, or if I need Optifine for that. If I needed Optifine for it, I will cancel the model thing and and work on the rest, just because I wanted to play the 1.17 snapshots and have the latest player safety features.
The pictures you see for the project on the top are screenshots of me playing development phases of the resource pack, plus some other packs I was playing for fun.
