# Frequently Asked Questions (FAQ)

## Fix "RuntimeError: Error loading DNA: DNA signature mismatched, expected DNA, got ver?"

In order to fix this issue, you should install [git-lfs](https://git-lfs.github.com/), and clone the repository again. 
DNA files will be downloaded correctly then.
If you cannot install git-lfs, you can download DNA files manually.


## How do I distribute a Maya scene?

Your scene should work out of the box if you include the following in the distribution:
- Scene file (`.mb` file)
- DNA (`.dna` file)
- Workspace (`workspace.mel` file)

All of these files need to be distributed together. If those files are not bundled and you experience some issues with you rig in Maya, 
try the following steps:

### How do I share the generated files?
If you want to distribute a generated Maya scene to other users, you must distribute the `.dna` file and `workspace.mel` together with the scene.

### How do I open a generated scene?
Before you load a generated scene, follow these steps:
- From the main menu, go to File > Set Project.
- Select `workspace.mel`
- Set the containing folder (with generated maya scene, `.dna` file and `workspace.mel`).


### How do I change the DNA path in the Maya scene?
