The present disclosure provides a development system to permit a developer to generate mixed reality (MR) streaming content for display on a VR headset worn by a viewer. The system allows development and generation of the content steam by non-technical personnel, where such developers are not required to possess computer skills or engineering knowledge. The streaming content generated includes embedded pre-recorded video files originally recorded in a 360 degree format, which significantly reduces computer processing time, memory requirements, and significantly speeds up the development time required to produce a final executable streaming content.
