Hello Meta Quest community! I have some questions I'd like to ask you, in case someone can help me solve them. I need to develop a virtual reality application for Quest 2 and Quest 3 in the near future. The application consists of a 360-degree virtual tour. I'm working in the Unity 3D environment and I'm having an issue with the file size of the videos in the build. I don't want to include the videos directly in the build; instead, I'd like users to be able to access a folder from the headset and play the videos from there, similar to what Bigscreen does. However, I've read in several places that Oculus doesn't allow accessing files from within an app. Is this true? If so, can you provide me with any solutions? I appreciate any help you can provide in advance.
