SkyBlock Amplified Nether Compat
This datapack enables compatibility between two popular Minecraft add-ons: Standard SkyBlock and Amplified Nether.
Compatibility is achieved by extending the height of the Nether dimension to 384 blocks while maintaining the void world concept characteristic of SkyBlock mode. As a result, players gain the ability to build at significantly greater heights than in the standard version.

For proper operation, both main datapacks must be installed, and this compatibility patch should load last in the list (i.e., positioned above the others). The loading order of the two main add-ons doesn't matter.
After installing all three components, the Nether will have increased height but will remain completely empty, consistent with the SkyBlock concept. This solution will particularly appeal to those who want to create large-scale builds with greater vertical freedom.
