i managed to get the thing installed and new seeds made, but the essences don't become anything. is there a recipe template?

The intention is to create your own recipes using a datapack or other means.

i have the same problem too. Can anybody help?

I now solved the Problem with Minetweaker.

1. installed Minetweaker Mod
2. created Folder "scripts"
3. created a ".zs" file inside that folder (name doesn't matter) with the following Code:

craftingTable.addShaped("shaped_example_1", item:mysticalagriculture:prosperity_shard * 6, [
[item:mysticalagriculture:prosperity_essence, item:mysticalagriculture:prosperity_essence, item:mysticalagriculture:prosperity_essence],
[item:mysticalagriculture:prosperity_essence, item:minecraft:air, item:mysticalagriculture:prosperity_essence],
[item:mysticalagriculture:prosperity_essence, item:mysticalagriculture:prosperity_essence, item:mysticalagriculture:prosperity_essence]
]);

Like that i created a Crafting Recipe for Prosperity Shards with Prosperity Essence
