Some people like the old netherrack because if fits with the Nether's theme, and i partially agree with that, but it looks kinda ugly. So i tried to make it look nice while still looking like the old texture, and the result was this!
What i did was basically make old netherrack transparent then put it over new netherrack and then made it use new netherrack colors.

This pack is compatible with Netherite Ore! Just put this one on top, and it should work!
