Unfortunately, we haven’t been able to reproduce this on a new project but we have been looking into differences in our project vs. the stock project to see what is causing this. The project that isn’t working was not started as a GearVR project. We’ve been trying to convert it over and this seems to be the only remaining issue. We have actually been able to create a working package using the Launch\Project Launcher option in the editor by setting up a custom Launch Profile that tells it to package the data. I’m not yet sure if this works fully without the hack I put in to make all texture formats supported but if so, we may just go with that for now. I’m just not sure what the differences are between cooking using the Launch menu vs. the Package Project menu.
