# DNAViewer
|
|
The [`dna_viewer`](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/dna_viewer) contains all the needed classes for reading and creating a functional rig in Maya from the DNA file.
|
|
It is organized in a way that allows every option to be configurable, so you can easily get the exact result you want.
|
|
|
|
## Examples
|
|
- [Generates rig](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/examples/dna_viewer_build_rig.py)
|
|
- [Export FBX per LOD](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/examples/dna_viewer_export_fbx.py)
|
|
- [Propagate changes from Maya scene to dna](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/examples/dna_viewer_grab_changes_from_scene_and_propagate_to_dna.py)
|
|
- [Simple UI](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/examples/dna_viewer_run_in_maya.py)
|
|
|
|
|
|
## Usage from code
|
|
There are two [APIs](dna_viewer_api_md):
|
|
- [build_meshes](dna_viewer_api_build_meshes_md)
|
|
- [build_rig](dna_viewer_api_build_rig_md)
|
|
|
|
## Usage in Maya
|
|
Usage in Maya is explained [here](/dna_viewer_maya_md)
|
|
|
|
|
|
## Folder structure
|
|
|
|
- [builder](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/dna_viewer/builder) - Contains the builder classes, which are used for easily adding configuration options
|
|
and building the scene, configurations, meshes, etc..
|
|
- [dnalib](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/dna_viewer/dnalib) - Contains classes for nicer API accessing DNA file.
|
|
- [ui](https://github.com/EpicGames/MetaHuman-DNA-Calibration/tree/main/dna_viewer/ui) - Contains the classes needed for the Maya UI.

The flow of the scene building process is the following:
