I think i found a bug.
I used ue 4.16 for my VR ArchViz project. I have used predict projectile path by object type to detect material on the hited actor on impact point face. This allowed me detect materials that support teleportation.
Few days ago i decide to change ue version to 4.18 due lighting updates. So here the problem, in ue 4.18 predict projectile functions do not return face index in hit results. The face id always -1. But line trace is still working good and i can receive face id.
So in this case i forced to use construction like this, and i think this is not proper.
If this planned decision, please can you explain, if not - you know about it.
Good Luck and sorry for my English!
