Model Viewer
The Model Viewer lets you place 3D models, Videos, Audio and Images into a folder and quickly view them. This can also be set up using the GUI
Either create a new folder in the "collections" folder in the model viewer and add your models there, along with folders for "Videos", "Audio" and "Images". You can simply drag and drop the model into a collection and now it is ready to be viewed in VR.

To view the model collection, run ModelViewer.py, choose your hardware and choose the collection you want to view
Press either the 'v' and 'c' keys, the X and Y LH controller buttons (these can be configured to be different buttons or event in the mediaConfig.py file) , use the optional scene controller tool by grabbing the tool with your controller trigger or left mouse button and clicking on the button that says "Next Model", or have the models change on a timer by setting Timer=True in the mediaConfig.py file and choosing how many seconds to have it model play after TimerValue = .
Grabbing Objects and Adding as Objects of Interest for View Count and Fixation Duration Information
To grab objects and add them as objects of interest you can add the word "_tag" after an object when setting up your scene in Inspector
Additionally if you add the TV_Stand Object you can have a video play for each scene if you place it in a folder called "Videos" and title it the same name as the environment model (i.e. LectureHall.osgb model name and LectureHall.mp4 video)
The same goes for images in an "Images" folder, audio in an "Audio" folder
If you end the name of your environment and video with "_Large" it will play the video on a large, IMAX style screen (which can be stereo or monoscopic).
