there seems to be 2 problems with unreal5 right now.
1-Substepping works differently. It does not work as we expect and simulation gets erratic at low frame rates. On the other hand async tick option is now available which sounds like the system in unity. It works allright(still experimental feature) and it’s the obvious choice to pick when it comes to replication.
2-Sometimes vehicles suddenly stop/freeze while flying. This is a very strange problem and it looks like a physics bug to me. i discovered that if you disable downforce in aerodynamics component this problems goes away but it doesn’t make sense since we just apply some extra force to the rigidbody.
When we address these problems the rest is easy to port we hope…
