Blender

To Start

1. Introduction

Welcome to the documentation on importing and using VRM files in Blender. VRM is a popular format for 3D avatars and models used in virtual reality and gaming applications. This guide will walk you through the process of importing, manipulating, animating, and exporting VRM models within Blender.

2. Prerequisites

Before you begin using VRM in Blender, make sure you have the following prerequisites:

• Blender: You need to have Blender installed on your computer. You can download the latest version of Blender from the official website.
• VRM Importer Add-on: To import VRM models into Blender, you'll need to install a VRM importer plugin. We will guide you through this in the installation section

3. Installation

To import and use VRM models in Blender, you'll need to install a VRM importer plugin. Here's how to do it:

1. Open Blender.

2. Navigate to "Edit" -> "Preferences."

   

3. In the Preferences window, click on the "Add-ons" tab.

4. Click install

   

5. Search the Add-on that you previously installed.

6. Activate it.

1. Click the "Save Preferences" button to save your changes.

With the VRM importer plugin installed, you're ready to start working with VRM models in Blender.

Introducing the VRM

1. What is VRM?

VRM (Virtual Reality Model) is a file format designed for 3D avatars and models used in virtual reality applications, games, and other interactive experiences. VRM files typically include 3D mesh data, textures, skeletal information, and animation data.

2. VRM Features

• Universal Compatibility: VRM is designed to be compatible with a wide range of virtual reality platforms and game engines, making it a versatile format for creating 3D characters.
• Expressive Characters: VRM models can be highly expressive, with support for facial expressions, body movements, and animations.
• Standardized Format: VRM follows a standardized format, making it easy to create, share, and integrate 3D characters across different applications.

Using VRM in Blender

1. Importing VRM Models

Now that you have Blender and a VRM importer plugin installed, here's how to import VRM models into Blender:

1. Open Blender.
2. Go to "File" -> "Import" -> "VRM."
3. Browse and select the VRM file you want to import.
4. Configure import settings such as scale and pose (if applicable) in the VRM import dialog.
5. Click the "Import" button.

Blender will now import the VRM model into your scene. You can manipulate and animate it like any other 3D object.

2. Manipulating VRM Models

Once you've imported a VRM model, you can manipulate it using Blender's standard tools. This includes:

• Moving: Select the model and use the Move tool (shortcut: G) to move it around the scene.
• Rotating: Select the model and use the Rotate tool (shortcut: R) to rotate it.
• Scaling: Select the model and use the Scale tool (shortcut: S) to resize it.
• Editing: You can also edit the mesh of the VRM model by entering Edit Mode (shortcut: Tab).

3. Animating VRM Models

To animate VRM models in Blender, you can use keyframes and the animation timeline. Here's a simplified process:

1. Select the VRM model you want to animate.
2. Go to the frame where you want to start the animation on the timeline.
3. Adjust the model's position, rotation, or scale as desired.
4. Press the "I" key and choose the type of keyframe you want to insert (e.g., Location, Rotation, Scale).
5. Move to a different frame on the timeline and adjust the model's properties again.
6. Insert another keyframe.

Repeat this process to create animations for your VRM model.

4. Editing and Creating Blendshapes for Facial Expressions

Blender also allows you to create and edit blendshapes for facial expressions of your VRM model. Here's how:

1. Select the VRM model.
2. Go to the "Object Data Properties" tab in the Properties panel.
3. Look for the "Shape Keys" section.
4. Click the "Add a Shape Key" button to create a new shape key.
5. Rename the shape key to represent the facial expression you want to create.
6. Enter Edit Mode (shortcut: Tab) and modify the mesh to form the desired expression.
7. Use the slider to control the intensity of the facial expression.
8. You can add multiple shape keys for different expressions.

5. Exporting VRM Models

Once you've finished working on your VRM model in Blender, you can export it back to the VRM format for use in other applications. To do this:

1. Select the VRM model you want to export.
2. Go to "File" -> "Export" -> "VRM."
3. Configure export settings such as compression and output file location.
4. Click the "Export" button.

Your VRM model will be saved in the VRM format, ready for use in virtual reality applications, games, and more.

6. Anything you can think of

Blender is a program to create 3d models so you can do whatever you want with your vrm.

1. Click the "Save Preferences" button to save your changes.

With the VRM importer plugin installed, you're ready to start working with VRM models in Blender.
