I made a model using OBJ files then the item goes wrong

[LeoCTH]

how to make the item render properly in the inventory?

this is my json

{

    "forge_marker": 1,

    "defaults": {

        "model": "mff:antenna_model.obj"

    },

    "variants": {

        "normal": [{

                "textures": {"#normal": "mff:blocks/antenna_texture"}

        }],

        "inventory": [{

                //TODO

        }]

    }

}

Before you register your models during preInit or during the ModelRegistry Event, you need to call OBJLoader.INSTANCE.addDomain(your-mod-id)

This is to signal Forge that "hey, at least one of my models are going to be .obj, so have that loader checking my stuff as well".
 

I also have a working BlockState.json for a .obj model here. Feel free to take a look.
