TunaMetaPack All Tutorials Link

We are pleased to announce the release of the tunaMetaPack, developed in-house by our team.
This tool is part of our proprietary suite, tunaTool, and was previously used internally for our ‘Customized Metahuman‘ services. Now, we are excited to make this toolset available to users.

The tunaMetaPack allows users to replace any character they have with Metahuman rigging, without restrictions. We provide a Maya application tool that facilitates this, and have included tutorials that cover the entire process—from the initial retopology stage to transferring the assets into the engine.

All functions that metahumans can operate are possible, including metahuman animator, liveLink Facial, etc.

The video below shows various function tests.

The toolset includes the following components:

• TunaUtils: Provides convenient and easy-to-use functions for various rigging scenarios.
• MeshWarp: Offers functionalities such as warping surrounding meshes attached to a source mesh with the same topology to match the shape of the target mesh, as well as mesh blending adjustments and other diverse features.
• MetahumanSet: Includes numerous features for Metahuman body rigging, such as no remit to change body joint angles, auto body rig, auto skinning, auto shader, RBF pose editing, head rig connection, and more.
• Ultimate DNA Editor: Enables full access and modification of Metahuman DNA, auto transfer to other meshes, behavior joint movement adjustments, behavior retargeting, additional blendShape settings, and replacement for each LOD. (These changes are recorded directly in the DNA itself, so when the DNA is loaded into the viewer later, all changes are applied.)
• External Tools : For the convenience of user installation When you install this package, the DNA Calibration library will be automatically installed. that library includes Epic Games’ PoseWrangler and DNA Viewer. These external tools are completely unrelated to the pricing of this tool, and we clarify that they are offered at no cost.

Epic Games’ Metahuman continues to be beloved by many users and is utilized in various applications. However, when it comes to customization, there are still significant limitations when converting a user’s existing character directly into a Metahuman. we are now ready to release it.

We aim to provide users with a pipeline that allows them to convert any bipedal humanoid character into a Metahuman rig. There are no restrictions—character proportions, initial joint angles, poses, or appearance don’t matter. We have detailed the entire conversion pipeline in a tutorial, covering every step from start to finish.

We hope these tools will empower you to achieve convert your character to metahuman rigging goals with ease and flexibility.

All you need is : R3DS Wrap, TunaMetaPack, Your character mesh

Retopology Pipeline – R3dsWrap Need!

To help you convert your custom character mesh into Metahuman topology, we’ve included a tutorial on how to properly perform this conversion using R3DS Wrap. Although this part is independent of our tools, the tutorial is designed to be accessible so that anyone can learn and apply these techniques.

Mesh Develope Pipeline – MeshWarp

By using the meshWarp feature in our tunaMetaPack, users will learn how to warp another meshes and quickly modify meshes, automatically generate LOD meshes, create additional meshes (e.g., eyelashes, eyeballs), and convert low-polygon meshes into high-polygon ones.

Metahuman Body Rigging Pipeline – MetahumanSet

With the metahumanSet feature in tunaMetaPack, users will learn essential techniques for Metahuman body rigging, including joint setup. You’ll also discover how to use both Epic Games’ tools, such as Pose Wrangler, alongside our metahumanSet to correct RBF Pose joints. Additionally, the tool will guide you through head rigging connections and various other critical steps.

Facial Rig DNA Pipeline – Ultimate DNA Editor

The Ultimated DNA Editor in tunaMetaPack allows users to modify nearly every aspect of Metahuman DNA. You can view all DNA data which has hidden from the DNA Viewer but also make extensive changes to DNA data. This includes swapping your mesh, adjusting joint movements in rig logic, and replacing or adding blendShapes for any LODs. We’re also planning an update to allow users to insert custom Rig Logic into the DNA—enabling you to incorporate your own rig logic instead of using Epic Games’ default Metahuman logic.

While the tools and pipeline we developed may be slower than other one click type external tools, we are confident that we offer greater accuracy in rigging process.
