Before you can start using Atoms in your 3D application, you have to initialize your scene.
Some tools (i.e. Atoms UI) require your scene to be initialize, in case you haven't done that before opening such tools you will be prompted a dialog asking if you want to intialize it.
Alternatively you can initialize your scene manually via the shelf or the Atoms Menu: Atoms > Scene > Init Scene.
When a scene is initialized one or more nodes (depending on which 3D application you're working with) will be created.
In all 3D application a node of type tcAtomsNode will be created. This node has one attribute containing the data for your agent variations and one attribute containing the data for your scene (Agent Types, Animation Clips, etc.). The data is stored on those attributes as json strings.
We provide tools for editing this json data, but you are allowed to create or edit it manually or with a script. Please be careful when doing this as you might break your scene.
You can find tools for exporting and importing your scene and variation data under the Atoms Menu.
