[1.12.2] ItemBlock model not being applied

[tripl3dogdare]

I'm working on a small mod that revolves around a specific block, and I've more or less got the functionality down. The issue I'm having is with the models - I've managed to get the model to apply when the block is placed in the world, but I can't get the item to be modeled in the player's inventory. It just shows up as the default flat black/magenta checkerboard in its slot, and as an overlarge block of the same texture when held. I wouldn't normally ask for help with something so mundane, but I'm legitimately stumped what I'm doing wrong. I've tried just about everything I can think of, including converting the blockstate JSON to Forge's format, changing paths, everything. The registry code is clearly working at least in part, since the block model works when it's placed, but the item just refuses to work.

 

ClientRegistry.kt

@SideOnly(Side.CLIENT)
@Mod.EventBusSubscriber(Side.CLIENT)
object ClientRegistry {
  @SubscribeEvent
  fun registerModels(e: ModelRegistryEvent) {
    ModelLoader.setCustomModelResourceLocation(
      Registry.itemBlockAutocrafter, 0,
      ModelResourceLocation(Registry.blockAutocrafter.registryName!!, "inventory"))
  }
}

 

blockstates/autocrafter.json

{
  "variants": {
    "normal": { "model": "autocrafter:autocrafter" },
    "inventory": { "model": "autocrafter:autocrafter" }
  }
}

 

models/block/autocrafter.json (copied wholesale from the Crafting Table, going to edit more later)

{
  "parent": "block/cube",
  "textures": {
    "particle": "blocks/crafting_table_front",
    "down": "blocks/planks_oak",
    "up": "blocks/crafting_table_top",
    "north": "blocks/crafting_table_front",
    "east": "blocks/crafting_table_side",
    "south": "blocks/crafting_table_side",
    "west": "blocks/crafting_table_front"
  }
}

 

models/item/autocrafter.json (again copied/modified from the Crafting Table)

{
  "parent": "autocrafter:block/autocrafter"
}
