Thank you very much! This works like a charm with Unreal Engine 4.16.3. It is a great feature as it considerably improves the performance. You really made my day!
I will also point to your reply in this issue: Dedicated server and Blueprint Nativization - Blueprint - Unreal Engine Forums as it was also requested there.
I cannot test with 4.17 yet due to different issues, but for now, all is great!
