  7. You can now press save to backup the procedure, anyways, it would save automatically.

  8. When you are done with editing the procedure, and want to start the animation process, switch to Unity with your model. If you don't have a project set up, refer to 3D Studio work flow

3. Name the interaction and press the Done button.

4. The procedure will be added to the Hierarchy under Interactions.

Models are not highlighted when testing the procedure
​Cause: "Highlight" models are not set.

  1. Select the interaction object in scene

  2. In the inspector, look for the "Activator Objects" field

  3. Drag the objects you wish to highlight into the list

  4. The models should now act as an "Interactive object" and the interaction will wait until the user has pressed on the object, when play testing.

Interactions are not updated when play testing
​Cause: Interactions might not be linked to the server

Sometimes interactions might lose their "link" to the ones that have already been uploaded to the server.

  1. Select the interaction object in scene

  2. Open the Interaction Menu ( LLS > Interactions Menu )

  3. Find the relevant interaction in the Interactions menu

  4. While the related interaction object is select, press on the "Link" button next to the interaction in the list.

  5. Check that it is linked by clicking on the interaction in the interactions menu, if this action selects an object in the scene, it means they are connected.

  6. Save the scene
