Hi Andrew,
unfortunately the game never gets to that point. I get the splash screen and then it crashes before the level shows up, I imagine when it gets to the point of loading that data.
I did notice something interesting though - I decided to check in my data and do a build of the same data from my Mac to see if it would work. My guess was that Windows Unreal was just not building the asset properly for iOS. Sure enough, the build worked just fine. Curiously enough though, I created a new mesh with the same issue and same fix when built from OSX. Could this be an issue with how my FBX from Maya 2016 is being read in and built in either OS? Or is there a particular setting that needs to be set for iOS usage (that I may have set without knowing it with the other objects I have that worked)?
