This guide will tell you how to set up your file structure to make a resource pack.

Requirements: Windows 10 21H1 or later.

1. Go to your .minecraft folder.
2. Then find the resourcepacks folder
3. Create a folder with a name that you want (for example: My custom M-Train)
4. Create a new folder inside of the existing folder called assets.
5. Upload a pack.png to your folder, this image will show in the resourcepack selection screen and should be 128×128.
6. Download this template pack.mcmeta and put it into your resourcepack folder:

pack.mcmeta

{
    "pack": {
        "description": "put your pack description here",
        "pack_format": 9,
    }
}

• Create a new folder named MTR in the assets folder.
• Create a text file inside the folder named mtr_custom_resources.json

To format your JSON file, simply copy, paste & edit some of the values. The main code is here:

If you have just one train:

mtr_custom_resources.json

{
	"custom_trains": {
		"{Base_Train_Name_here}": {
			"name": "My Custom Train Name",
			"color": "#66CCFF",
			"base_train_type": "sp1900",
			"texture_id": "mtr:{FOLDERNAME}/{TEXTURENAME}.png"
 
		}
	}
}

If you have more than one (you cannot simply duplicate the piece above, as this messes with the json format):

mtr_custom_resources.json

{
	"custom_trains": {
		"{Base_Train_Name_here}": {
			"name": "Another train name here",
			"color": "66CCFF",
			"base_train_type": "sp1900",
			"texture_id": "mtr:{FOLDERNAME}/{TEXTURENAME}.png"
 
		},
 
		"{Base_Train_Name_here}": {
			"name": "Another train name here",
			"color": "66CCFF",
			"base_train_type": "sp1900",
			"texture_id": "mtr:{FOLDERNAME}/{TEXTURENAME}.png"
 
		}
	}
}

1. Download an image editing software of your choice, that supports transparency. Recommended are Paint 3D and GIMP, as they are both free and relatively easy to use. Do not use MS Paint, because it does not support transparency and will cause all transparent parts of your texture to turn white
2. Go to https://github.com/Minecraft-Transit-Railway/Minecraft-Transit-Railway/tree/master/fabric/src/main/resources/assets/mtr/textures/vehicle and download the texture file you want to edit
3. Open your image editing software, find the texture you want to edit, then open it and start making your edits
4. When you're done, export the texture file as a PNG to your resourcepack, and put it in the appropriate folder (re-read the section above on making a resourcepack if you're unsure of how and where)
5. Follow all the correct steps to create the resourcepack, as seen above
6. Make sure you use the correct base train type. These types can for now be found on the github itself, as the model files have the same names, but in the future, there will be a page for it on this very wiki.
7. All that is left is to put it in your resourcepacks folder and start your MTR installation!

And you are done with the basics!

• Download Audacity, you're going to need it.
• Record any sound file, or perhaps download one from an external source. Make sure its in .ogg format and the filename doesnt contain any uppercase letters.

• Make sure you have two long sound files that sound approximately like your train accelerating from 0 to about 160-200 or so, and decelerating the other way (since sometimes the sound may vary between the two, such as brake whine or motors only making sound when accelerating) you may also use a single file if acceleration and braking is identical.
• Open this sound file in Audacity, select the sound in the timeline and then find “Regular Interval Labels” under “Tools” at the top.
• Choose the amount of sounds you want to end up with. More is not necessarily better, but does give better precision if sounds change drastically over a small time frame. Try to make the files approximately half a second to a second long.
• Now click export, and select “Multiple Files” below, click “Labels”, then hit export. (Make sure again to export them as mono .ogg files)
• Now comes the fun part! You have to manually rename EVERY. SINGLE. SOUND FILE. Follow a pattern that goes speed_0a, speed_0b, speed_0c, speed_1a, speed_1b, etc.
• Go back to the mtr folder inside your resourcepack and create a new folder within that called sounds, create another new folder inside that called whatever you want, then paste the sound files in a folder called acceleration or deceleration. That second-to-last folder will be your “sound id” that you will have to specify later in the process.
