### Full Example: Building Meshes in Maya

Source: https://epicgames.github.io/MetaHuman-DNA-Calibration/dna_viewer_api_build_meshes_md.html

A comprehensive example demonstrating environment setup, DNA loading, and mesh building with both default and custom configurations in a Maya context.

```python
from dna_viewer import DNA, Config, build_meshes

# if you use Maya, use absolute path
ROOT_DIR = f"{ospath.dirname(ospath.abspath(__file__))}/..".replace("\", "/")
# Sets DNA file path
DNA_PATH_ADA = f"{ROOT_DIR}/data/dna_files/Ada.dna"
dna_ada = DNA(DNA_PATH_ADA)

# Starts the mesh build process with all the default values
build_meshes(dna=dna_ada)

# Creates the options to be passed in `build_meshes`
config = Config(
    add_joints=True,
    add_blend_shapes=True,
    add_skin_cluster=True,
    add_ctrl_attributes_on_root_joint=True,
    add_animated_map_attributes_on_root_joint=True,
    lod_filter=[0, 1],
    mesh_filter=["head"],
)

# Starts the mesh building process with the provided parameters
# In this case it will create every mesh contained in LODs 0 and 1 with 'head` in it's name,
build_meshes(
    dna=dna_ada,
    config=config,
)
```

### Build Character Rig Example

Source: https://epicgames.github.io/MetaHuman-DNA-Calibration/dna_viewer_api_build_rig_md.html

This example demonstrates how to build a character rig in Maya using the DNAViewer API. Ensure the environment setup is completed before running. It involves loading a DNA file, configuring RigConfig with GUI and script paths, and then calling the build_rig function.

```python
from dna_viewer import DNA, RigConfig, build_rig
import os

# if you use Maya, use absolute path
ROOT_DIR = f"{os.path.dirname(os.path.abspath(__file__))}/..".replace("\", "/")

# Sets the values that will used
DNA_PATH_ADA = f"{ROOT_DIR}/data/dna_files/Ada.dna"
dna_ada = DNA(DNA_PATH_ADA)

config = RigConfig(
    gui_path=f"{ROOT_DIR}/data/gui.ma",
    analog_gui_path=f"{ROOT_DIR}/data/analog_gui.ma",
    aas_path=f"{ROOT_DIR}/data/additional_assemble_script.py",
)

# Creates the rig
build_rig(dna=dna_ada, config=config)

```

--------------------------------

### Environment Setup

Source: https://epicgames.github.io/MetaHuman-DNA-Calibration/dna_viewer_api_md.html

Sets up the environment variables and system path to allow importing from dna_viewer. This code should be added at the beginning of your script.

```APIDOC
## Environment Setup

In order be able to import from dna_viewer, the environment needs to be set up. This is done by adding this code to the beginning of any example mentioned below:

```python
from sys import path as syspath
from os import environ, path as ospath

ROOT_DIR = fr"{ospath.dirname(ospath.abspath(__file__))}/..".replace("\", "/") # if you use Maya, use an absolute path instead
ROOT_LIB_DIR = fr"{ROOT_DIR}/lib"
if platform == "win32":
    LIB_DIR = f"{ROOT_LIB_DIR}/windows"
elif platform == "linux":
    LIB_DIR = f"{ROOT_LIB_DIR}/linux"
else:
    raise OSError("OS not supported, please compile dependencies and add value to LIB_DIR")


if "MAYA_PLUG_IN_PATH" in environ:
    separator = ":" if platform == "linux" else ";"
    environ["MAYA_PLUG_IN_PATH"] = separator.join([environ["MAYA_PLUG_IN_PATH"], LIB_DIR])    
else:
    environ["MAYA_PLUG_IN_PATH"] = LIB_DIR

syspath.append(ROOT_DIR)
syspath.append(LIB_DIR)

```

When running this from Maya, the `ROOT_DIR` should be set to an absolute path to the root of the repository instead.
```
