The Perfectionist's Amplified Nether is a pack that aims to make the Nether 256 blocks tall while retaining every other detail as exactly as possible, with an emphasis on good biome borders and accurate surface builders.

If you just try to extend the nether's height upwards, many things like surface builders will break. For example, the unique patterns on the Soul Sand Valley's floor and ceiling, the patches of netherrack and nether wart blocks in the Crimson and Warped Forests just... won't exist, and the Basalt Deltas' ceiling turns to netherrack above y=128. Basalt pillars in the Soul Sand Valley won't work at all, and in general most things just die because of hardcoding.

I've gone through significant effort to recreate these features as faithfully as possible. You'll recognize the familiar curves of soul sand and soil soil in the Soul Sand Valleys, the basalt ceilings in Basalt Deltas, and the patches of nether wart blocks and netherrack in the Crimson and Warped Forests. The ceilings are not perfect, unfortunately, because making them 100 percent perfect would mean unplayable lag during generation.

Please note that due to the techniques I've used here (particularly for the ceilings) the world's generation will likely not be as fast as vanilla.

This pack is based on the excellent work in FireNH's "Taller Nether" pack. His pack is better for performance, but provides a less accurate rendition of an amplified Nether.

One last thing - this pack is NOT compatible with Incendium! There will be an Incendium Amplified pack released at a later date.
