While you can open and initiate Chalk calls from within a Vuforia Studio experience, 3D models are not included in the session view. Today, Chalk sessions are not recorded. However, this feature is on the roadmap. We do currently have Session Summaries which are screenshots that are created each time an annotation is drawn. These are stored locally on the device and can be saved at the end of the session. For more information on session summaries, please see our Help Center.
