Armory bundle comes with everything you need. Currently, Blender 2.78 is used with Armory player built in. If you do not require the built-in player, Armory can be used as add-on only. Armory sources are available at GitHub.
- Unpack Armory_version.zip to your preferred location. On Windows, prefer a short path like ‘C:\Dev’ or unpack with 7-zip to prevent long path errors.
- Run Blender located in unpacked SDK. On Windows, you may need to enable it for the first time by clicking More info - Run anyway.
- To verify everything is working correctly, save your .blend file and hit Play in Viewport button, located in the 3D view header.
