I was using UEFN, I created a blank island model (within the platform) and when I tried to start a session, I couldn’t because of a validation failure. The Message Log says that “The level “MyProjectA” has 0 island configuration devices. The levels must have exactly 1. (ValkyrieValidator_WorldLimits)”. I don’t know how to add an island configuration device. I would like some help with this issue.
