Hey Keltar,
If you’re in Maya, you can try out our Maya Rigging Toolkit, which allows you to create an example character.
You can also export the Blue Mannequin skeletal mesh from the Content Browser as an FBX (right click on the skel mesh>Asset Actions>Export).
We also have a Blender file to download here. The blender file is currently being improved though, so the one available there may be a little out of date.
