I'm trying to add (ExNihiloCreatio) Sieve Meshes to Sieve enchantements but if I put the plain id (exnihilocreatio:item_mesh) I get a missing texture under the book (I think it's because the first mesh has metadata 1 and not 0). Instead metadata specific items (e.g. exnihilocreatio:item_mesh_1) are not supported.
