Prefab (Sphere Asset in this example)
| Info |

While it is possible to create these catalogs Catalogs and define the relationships between them manually, the Motive Asset Bundler provides a quick way to do this automatically. |
Step 6
...
: Storyflow - Add the
...
Object to a Named Object Catalog
Remember the name of the Motive Scene Object from step
...
(MySphere in this example)
...
Catalog item to a Named Object Catalog
If you have already done this, you can skip this step
Step 7

: Storyflow - Spawn the Asset with a Storyflow Script
Create a
...
...
Call the first child
...
Frame Setup
Add a Spawn Asset
...
Select the

Prefab name from the Unity Asset
...
Catalog (Sphere Asset)
Add a Scene Object Resource

Frame of the Setup frame with the
...
...
...
Select the Scene Object from the Objects menu
Select the
...
Anchor from the Anchor menu
| Info |

Important: Once the Spawn Asset resource Resource is used, you must refer to the object with the Scene Object name from that point on anywhere else in the scriptScript. |
Step 8
...
: Unity or Headset
Run the Storyflow
...
Scenario that is linked to the
...
Script created in step 7
The
...
Asset Bundle will be downloaded like any other piece of
...
Media and spawned into the
...
Scene at the coordinates defined in the
...
Anchor.
| Info |

This lets you inject a new asset Asset into an existing scene Scene without making a new Unity build or needing to redeploy an apk to VR headsets |
You can try running the same script Script in another sceneScene. You may want to use a different anchor Anchor in your Storyflow script Script but the asset Asset will appear just as easily in any other scene Scene with the same SF script.Storyflow Script.
