Enabling compatibility

Step 1

Install ItemsAdderBlocksInjector and don't remove it after installation!

Step 2

Create your Iris world (follow their guides) and use your ItemsAdder custom blocks IDs as you would do with vanilla blocks.
For example open this file of the overworld pack: plugins\Iris\packs\overworld\biomes\mountain\mountain.json
Then edit the layers settings to use a custom block, in this example the custom Amethyst Block:
1
"layers": [
2
{
3
"minHeight": 1,
4
"maxHeight": 1,
5
"slopeCondition": {
6
"minimumSlope": 0,
7
"maximumSlope": 2.6
8
},
9
"palette": [
10
{
11
"block": "itemsadder:amethyst_block"
12
}
13
]
14
},
Copied!
This will generate a similar result:

Compatibility issues

  • FastAsyncWorldEdit will stop working, there is nothing I can do about that.
  • WorldEdit //undo and //copy won't work with the custom blocks placed by Iris, they would be reverted back to NOTE_BLOCK (or mushroom, TRIPWIRE, CHORUS_PLANT)
