How to add signs, sounds, etc. to your resource pack

This guide will tell you how to add signs, sounds, etc. to your resource pack.

MTR4 format is used in this tutorial.

It is recommended to read adding_custom_resources first, as it contains information about the structure of an MTR resource pack.

In the MTR mod, it is possible to add your own custom signs, rails, objects and lift retextures by editing the mtr_custom_resources.json.

Adding new custom content to the pack

Create a folder under mtr with a name that you want (for example: custom_signs).

Note that you can only use a-z, 0-9, - and _ for the folder name. CAPITAL LETTERS, white spaces and any other characters are not acceptable.

Drop in the custom content that you will use.

Registering custom content

Return to mtr_custom_resources.json.

Custom signs

Compulsory components

mtr_custom_resources.json

{
	"id": "my_custom_sign",
	"textureResource": "mtr:custom_signs/custom_icon.png",
	"customText": "你好|Hello",
	"small": false,
	"flipCustomText": false
}

Replace the value of id with an ID that you like. Only a-z, 0-9, -, _ and ! are accepted.
Replace the value of textureResource with the path to the icon.

Optional components

Replace the value of customText with any text that you want to render. Use a vertical bar (|) to separate between two languages.
Set small to true if you want the icon to be rendered with a small padding around.
Set flipCustomText to true if you want the text to be rendered to the right.

Custom rails

Compulsory components

mtr_custom_resources.json

{
    "id": "my_custom_rail",
    "name": "My custom Rail",
    "color": "E5E533",
    "modelResource": "mtr:custom_rails/my_custom_rail.obj",
    "repeatInterval": 0.5
}

Replace the value of id with an ID that you like. Only a-z, 0-9, -, _ and ! are accepted.
Replace the value of name with a name that you like.
Replace the value of modelResource with a path to the model.
Replace the value of repeatInterval with the length of your model in metres.

Optional components

Replace the value of color with a HEX colour value that you like. This will change the colour of the small square next to the object to that value.

Custom objects

Compulsory components Inside the square brackets of „objects”, add the following code.

mtr_custom_resources.json

{
	"id": "my_custom_object",
        "name": "My custom object",
        "modelResource": "mtr:custom_objects/my_custom_object.obj",
        "textureResource": "mtr:custom_objects/my_custom_object.mtl",
        "color": "000000",
        "flipTextureV": true,
        "translation": [0,0,0],
        "rotation": [0,0,0],
        "scale": [1,1,1],
        "mirror": [false,false,false]
}

Replace the value of id with an ID that you like. Only a-z, 0-9, -, _ and ! are accepted.
Replace the value of name with a name that you like.
Replace the value of modelResource with a path to the model.
Replace the value of textureResource with a path to the model's texture.
Set flipTextureV to false if your texture is flipped.

Optional components

Replace the value of color with a HEX colour value that you like. This will change the colour of the small square next to the object to that value.
Modify the values of translation, rotation and/or scale ([x,y,z]) if you want the model to be rendered by default to have that value of translation/rotation/scale.
Set mirror to true if you want the icon to be rendered with a small padding around.

Custom lifts

Compulsory components

mtr_custom_resources.json

{
	"id": "my_custom_lift",
        "name": "My custom lift",
        "color": "CCCCCC",
        "textureResource": "mtr:custom_lifts/my_custom_lift.png"
}

Replace the value of id with an ID that you like. Only a-z, 0-9, -, _ and ! are accepted.
Replace the value of name with a name that you like.
Replace the textureResource with the path to the lift texture.

Optional components

Replace the value of color with a HEX colour value that you like. This will change the colour of the small square next to the object to that value.

Save the JSON file when you're done.

Please remember to validate your JSON file. Websites such as JSONLint may be used to validate your JSON. Minecraft will NOT load any custom resources in a mtr_custom_resources that is invalid!

Adding it to the game
