How to Make Your Own Custom Dimension in Java Minecraft 1.21.11+

You want to make your own dimension? You're in the right place. We'll talk about dimension files, dimension type files, noise settings, and biome files, and I'll point out how to modify each one. We'll change default blocks, dimension rules, change environment attributes, and add mob spawning in.
