As of E-Learning Lab 1.4.2 you can now add NPC agents to your scene. To do this, simply drag and drop or use the built in avatars in the "Avatars" tab of the assets browser.
Drag and drop from Avatars asset library to Inspector and place in your scene
Can then choose which animation state to play (view available states in Inspector under the "Animations" tab), and right click to set Facial morphs.
