User-created content can be added to the Minecraft Transit Railway mod via resource packs. Currently, players can add the following:

• Texture variants for existing trains
• Blockbench models (BBmodel) for trains
• New textures and/or text for railway signs

It is highly recommended to be familiar with creating a resource pack before proceeding with this guide.

The file mtr_custom_resources.json is the main file that will get loaded. This file defines custom content for the mod to register. It must be placed under the mtr namespace; in other words, it must have the file path of assets/mtr/mtr_custom_resources.json.

To add texture variants, the custom_trains JSON object should be added to mtr_custom_resouces.json. Each JSON object under custom_trains, representing a texture variant for a train, should have a unique key and serveral required entries.

An example is shown below.

{
  "custom_trains": {
    "my_custom_train": {
      "name": "My Custom SP1900 Train",
      "color": "FEC5E5",
      "base_train_type": "sp1900",
      "texture_id": "mtr:custom_directory/custom_sp1900.png"
    }
  }
}

Adding New Railway Sign Textures or Text

To add new railway signs textures or text, the custom_signs JSON object should be added to mtr_custom_resouces.json. Each JSON object under custom_signs, representing a new sign, should have a unique key and serveral required entries.

An example is shown below.

{
  "custom_signs": {
    "my_custom_sign": {
      "texture_id": "mtr:custom_directory/custom_sign.png",
      "flip_texture": false,
      "custom_text": "你好|Hello",
      "flip_custom_text": false,
      "small": true,
      "background_color": "1167B1"
    }
  }
}

Model Properties file

The Model Properties file can be edited by the Resource Pack Creator or directly in a text editor, for example.

Verifying the Resource Pack

Use a JSON validator to check for any syntax errors of the JSON files.

The resource pack (zip file) can be installed either clientside or as a server resource pack. If installed as a server resource pack, all players joining the server will be able to see the new additions after accepting the server resource pack.

Download the example resource pack to see a full example and to test out the functionality.
