🚩 Quest 1: Create a Texture Atlas

💡 What is a Texture Atlas?

It’s a single image that contains all the different art parts of your model—laid out in a way that VTube Studio can read and display them correctly.

🛠️ How to Make One

First let's click the Texture Atlas button up here on your tool bar.

The following window will appear:

The most important part here is to make sure your texture atlas size is big enough for all your model parts.

Let's change the width and height to 4096px by 4096px.
This will be big enough to lay out all the parts of the model while maintaining the quality. If needed, we can always generate a second texture atlas to fit additional parts.

Once you press ok, the software will take a bit to load, and the following window will appear:

The program has automatically laid out the parts of the model onto the texture atlas for you.
The most important thing, is that if we highlight all the parts by clicking and dragging, you will see the "Scale" of all the parts on the texture atlas.

After highlighting the parts, we can see the scale is 100%. This is perfect, we want to make sure that the scale is 100% so that image quality on export is full resolution!

Next we must make sure that all the parts are separated and none of them are touching. If they are touching, we'll have issues during export.
(Pieces will be displaying the wrong colours/textures!)

After confirming none of the pieces are touching, we can now create a second texture atlas to place the rest of the model parts.

We'll click "Add Texture..." at the top right, and select the same resolution.

A new blank texture will appear.

We can now double click on each part in the right side column, and all the parts will get places onto the top left of the atlas.
(Unfortunately, you'll have to double click each one, one by one.)

Don't worry about their position right now, we'll automatically organize them afterwards.

We can now click "Automatic Layout..." to spread these parts across the texture.

Once you click it, make sure you have the following settings.

Press ok, and allow the program to load. It will place everything that fits on this texture, and all parts that don't fit will be put back onto your right side column.

In this case, we'll need to make one more texture to fit the remaining art parts.

With all the textures made, and no remaining parts, we can press ok and let the software create the texture atlas.

🚩 Quest 2: Export the Model

  1. Click File > Export for Runtime > Export as moc3 file...

You’ll get a new window:

  • Make sure Export Physics Settings File (physics3.json) is checked
  • Click OK
  1. Choose a New Folder to save everything into
    (This is the folder you’ll later drag into VTube Studio)
  2. Press Save and let it export.

You should now see these files inside your folder:

  • yourmodel.moc3
  • model3.json
  • physics3.json
  • textures/ folder
  • motions/ folder (if you had any)
  • expressions/ folder (if you had any)

Your model is officially exported and ready for testing in VTube Studio!
