# Automation
## Setup
- Add Blender 3.6 to your PATH so it can be run from command-line (putting `blender` in cmd should open Blender 3.6)
- Ensure Python is installed on your machine
- Install Blender as a Python module (you might have to do this as administrator): `pip install bpy==3.6.0`
- Ensure you have Blender 3.6 installed (hopefully at the location: `C:\Program Files\Blender Foundation\Blender 3.6`)
- Run the script located at `pipeline/export_all_anims.cmd`
## Editing
- Ensure Python is installed on your machine
- Ensure you have Visual Studio Code installed
- Open this directory in VS Code and install the recommended plugins
- Open terminal, `cd` into `pipeline`, and run the following command: `$ git clone https://github.com/Korchy/blender_autocomplete.git`
- Your workspace is now set up!
## Resources
- [Blender as a Python Module](https://pypi.org/project/bpy/)
