Block Appearance

Machine block appearance is defined using the block property inside the appearance property.

This property is optional and will use the default machine model if not specified.

There is 2 way of using this property :

Using a blockstate

The block property can take a blockstate using the format : namespace:block_id[state1=value,state2=value...]

The blockstates properties are optional, you can just use namespace:block_id and the machine will use that block default state.

You don't have to use all the block's state properties, if some are not specified their default value will be used instead.

Example :

"appearance": {
    "block": "minecraft:furnace[lit=true]"
}

That way the machine will use the appearance of a vanilla lit furnace.

Using a custom model

If you don't want to mimic an existing block you can use the block property to point a custom model that the machine will use.

The model must be a Minecraft type json model, if you are not familiar with this type of model see the official MC Wiki (note : you need only the model and texture file but not the blockstates file)

The model MUST be loaded in-game using either a ResourcePack or a Resource Loader mod like Open Loader.

The model MUST be located in assets/namespace/models/machine any other model location such as assets/namespace/models/block will not work.

Example : A model located in assets/namespace/models/machine/my_machine.json must be defined as namespace:machine/my_machine, the model loader will search for files in the models folder and it's subfolders and will also add the .json so you don't have to.

Example :

"appearance": {
    "block": "custommachinery:machine/my_model"
}

That way the machine will use the file located in assets/custommachinery/models/machine/my_model.json as the machine model.

Adding a new custom model inside that directory will require a game restart

Notes

If you use a custom minecraft json model for your machine you can color some faces using the tintIndex property (inside the json model).

Available tintIndex values are:

• 1 : color the face using the biome water color
• 2 : color the face using the biome grass color
• 3 : color the face using the biome foliage color
• 4 : color the face using the Machine Appearance color property value

If you don't specify a tintIndex in the json model the face will use it's texture and not color it.
