Generation of ores in negative layers

It's probably a bug in the snapshot but for now you can go into the code of the block you want to generate and change the values in the numbers, it might cause some bug though because the code might need to do a extra thing to make it generate negative but you can try 

1. Click on Tools
2. Create Ore Pack
3. Give name, type, color, and power factor. Whwn done click on Create Ore Pack
4. Step #3 generates all the necesary code for the Ore Features
5. Go to your recently created ore, change any other value if needed.
6. At the top, click on Generated Code Viewer
7. At the bottom, click on <YOUR _ORE_NAME>OreFeature.java
8. At line #16, you will see something similat to the following - 
   

   List.of(CountPlacement.of(11), HeightRangePlacement.uniform(VerticalAnchor.absolute(1), VerticalAnchor.absolute(63))));
   

 Now that you know where it is located, save that block, lock the code and change that line in the code viewer. Change the VerticalAnchor.absolute(1) <<<=== to a negative value

List.of(CountPlacement.of(11), HeightRangePlacement.uniform(VerticalAnchor.absolute(NEGATIVE_VALUE_HERE), VerticalAnchor.absolute(63))));

Make sure you do not unlock the code when done, if you do ... MCreator will change all values to th default ore generation (it does not allow negative values). This also works for 1.17.x, not tested on 1.16.x.

Won't work on 1.17/1.16, they don't have -x blocks, only 0->256 NOT -64->320

Unless your mod adds that

It works on 1.17.x, yes ... my mod added it from -511 to 1024 using MCreator (https://mcreator.net/modification/81975/new-world-height-and-depth), and posted on this site. Also for 1.18.1, but never tested on 1.16.x. Will upgrade to 1.18.2 soon.
