Thanks for the reply to this thread. Def a different issue though. I don’t use the get display names for anything. I did at one point for “pickups”, nothing to do with line traces. This actually did work fine in packaged games, but I knew it wasn’t ideal way, so I changed that to get class and if class == whatever then carry on.
As for the traces, wasn’t doing display names at all. Was a simple trace on visibility channel. The characters were blocking the channel hence it worked just fine in the editor. When packaged it would just go right through the characters like it wasn’t seeing them. I left debugging on for the packaged game and could see them go thru the characters and hit walls.
Never resolved to this day, still using traces by objects. I’m on 4.15 now for that project… maybe its resolved in a later version… havent tried.
