Hello Unreal Community,
When i launch my packaged game, i can’t watch one map in HTC Vive. It appears on desktop but not in the gear. Moreover the map works good in editor. All of the others maps works good.
What i can do?
Thanks a lot for answers.

PS: Can you correct the mistake in the title please?
