Once we got the ball rolling, the biggest challenge was coordinating with engineers to implement something seemingly simple. (Side note- because of our amazing engineering team, we were able to implement this entire flow in UNDER A MONTH.)
We introduced a Metamask login and scoped out the flow from start to finish, assuming our users would want to instantaneously populate a gallery. We hit a roadblock when we realized our content management system wasn't suitable for this flow. It wasn't easy to navigate content, and there was no way to multiselect. So, the new "Stuff" menu was born.
After multiple iterations with Eng, we were able to complete an MVP design including single frame upload and replacement. Unfortunately, for now VR headset would not have auto gallery functionality, and we would push users to our web platform.
