Avatar Toolkit is in Alpha and will contain issues, please ensure you report them!

Avatar Toolkit is a modern, Blender addon designed to streamline the process of preparing 3D avatars for virtual platforms including VRChat, ChilloutVR, Resonite, and other similar applications.

What is Avatar Toolkit?

Avatar Toolkit simplifies the workflow for avatar creation and optimization by providing an all-in-one solution that:

• Automates complex optimization processes like mesh joining and vertex merging.
• Provides advanced tools for eye tracking setup and viseme configuration.
• Offers specialized armature utilities including bone name conversion for different platforms.
• Includes performance-focused optimization tools so you can optimize your avatar for platforms like VRChat and ChilloutVR.

The addon is built with a focus on user experience, reducing the number of steps needed to prepare avatars while offering powerful customization options for advanced users. Avatar Toolkit aims to be a complete replacement for Cats Blender Plugin and its unofficial variants, with a modern codebase designed specifically for current Blender versions and minimal dependencies on third-party plugins.

Requirements

1. Blender Version

• Blender 5.1 or newer is required
• Blender 5.1 is the current recommended version

2. Python Requirements

• If using a custom Python installation with Blender, ensure NumPy is installed
• Default Blender installation includes all required packages

3. Recommended Setup

• Download Blender directly from https://blender.org
• Use Blender 5.1 for the best experience

Unfortunately, due to the increased number of people complaining to me (yes, we get DMs about this) that AT or CATS is broken when it's not, we are going to have to be a bit more strict about which Blender releases we will provide support for.

We only support the following Blender releases:

• Steam release
• The Blender website releases (there are downloads for Linux, Mac, and Windows)

We do not support the following what so ever and we will not give help if your running the following.

• We do not support the Windows Store due to it causing issues, and we also don't support the Snap Store for Linux.
• We do not support package manager releases on Linux. This is because package managers are normally run by the distro, and a lot of the time the distro will build Blender themselves and make their own changes which are not sanctioned by Blender (for example, bundling a newer version of Python which tends to break plugins). If you report a bug from anything apart from the Blender versions we support, you will be told we can't help you from now on.

Additional Plugins Requirements.

Currently None.
