Hi Jin_VE,
Thanks for the swift reply! We’ve added this flag to our Target.cs.file. However we found out that on UE4 4.17.2 this causes an packaging error as confirmed by this thread. We found out that 4.18 P2 has a fix for it, so we pulled that commit through Github on our custom UE4 engine. However, even with that changelist (UE-49632), it still produces the same packaging error. So that options seems closed for the time being. Once again, thanks for taking the time to respond to this thread!
