MetaHumans created there can be downloaded through Quixel Bridge, directly into Unreal Engine, with only a few clicks-like any of the thousands of other assets found there. What is a MetaHuman?Ī MetaHuman is a high-quality digital character that is created in the Unreal Engine online application MetaHuman Creator. The project will not look as intended, but you can still explore how the content is set up. MetaHuman DNA Calibration is released with licence.While it is possible to open and run this project without the recommended hardware specifications above, the lighting and features of the project are designed with these in mind. See the FAQ guide for additional specifications. Important: Use / (forward slash), Maya uses forward slashes in path.

c:/MetaHuman-DNA-Calibration in Windows or /home/user/MetaHuman-DNA-Calibration in Linux. If a user runs examples in Maya 2022, the value for ROOT_DIR should be changed and absolute paths must be used,Į.g. Two demo DNA files are provided for easier testing of this tool. These names are embedded as prefixes: dna_, dnacalib_, and dna_viewer_. Note: Examples are grouped in three groups: DNA, DNACalib, and DNAViewer.

Propagating changes from Maya scene to dna.

Simple UI in Maya and some documentation for it.

Create a new DNA from an existing one by extracting specific LODs.

Read binary DNA and write it in a human readable format.

Several Python examples are provided for reference and can be found in the examples' folder:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:ĭNAViewer can be used in mayapy (Python interpreter shipped with Maya) or in Maya 2022, except Propagating changes from Maya scene to dna which can be used just in Maya.

If running on Linux, please make sure to append the LD_LIBRARY_PATH with absolute path to the lib/Maya2022/linux or lib/Maya2023/linux directory before running the example: 'OS not supported, please compile dependencies and add value to LIB_DIR'

in case of Maya's interpreter (mayapy) you will have to initialize maya with:įrom os import path as ospath from sys import path as syspath from sys import platform ROOT_DIR = f' /linux' else:.

If you plan to run the script from command line:

add MetaHuman DNA Calibration location to MAYA_MODULE_PATH system variable (if you want to use MetaHuman DNA Calibration in Maya).

In order to use MetaHuman DNA Calibration in your scripts, you need to: Note: Maya 2022 is bundled with Python 3.7, Maya 2023 is bundled with Python 3.9.

If you are not using git-lfs, you have to download DNA files manually.ĭNACalib can be used in C++ projects as a C++ library.ĭNACalib Python wrapper can be used in Python 3.7 and 3.9, mayapy (Python interpreter shipped with Maya) shipped with Maya.

Git-lfs is installed and configured to use.

They are downloaded with the rest of the code if If a user has a different platform or architecture, the library and its dependencies must be compiled.ĭNA files are stored as LFS (Large File Storage) files. If you are using a different version of Python, you must recompile it. Pre-compiled binaries for Windows and Linux (both 64-bit) are part of the repository.

External Software DependenciesĭNACalib's Python wrapper is compiled against Python 3.7 and 3.9.

However, the following joints are used for connecting head with body and should not be removed or renamed: neck_01, neck_02, FACIAL_C_FacialRoot.

Note: DNACalib library allows removal and renaming of any joint.

Change neutral joint positions, neutral mesh positions, and blendshape delta values.Īn overview of the MetaHuman DNA file format can be found here.

Remove joints, meshes, and / or joint animation.

Rename joints, meshes, blendshapes, and / or animated maps.

With DNACalib, you can make the following changes in DNA files: To use these tools, you should be familiar with:ĭNACalib and its API are used to inspect and modify DNA files. The MetaHuman DNA Calibration repository contains two distinct tools: Overviewįor an explanation about how the repository is organized, click here. MetaHuman DNA Calibration tools are provided in a GitHub repository located at this address. We wanted to share this code to help users customize DNA files so they can better integrate the characters they create into their games and experiences. MetaHuman DNA Calibration is a set of tools used for working with MetaHuman DNA files, bundled into a single package.
