Hello community and Epic staff, I’m having an issue with getting the ‘lighting needs to be rebuilt’ in the standlone package of my game. Once the lighting is complete in engine the game doesn’t produce this error message in PIE, just when I package the game (packaging for windows 64 bit). Is there any way to tell in editor what specifically Isn’t built? I have a pretty large map and only 600 off things are showing up at the end of it to be unbuilt. I thought this could be something related to a Construction script changing a procedurally created mesh at startup, but that mesh is set to movable so that should make much difference right?
The only other thing that I can think of that may be causing the issue is (because this is a recent issue, i never had it before) either 4.8 or some instanced mesh foliage i created. This grass has 2 LOD’s and the 0LOD has an interpolating wind opacity based on the players camera distance and absolute world position. Weather the swapping of these is causing the issue I don’t know.
What else could be causing this and how can i diagnose/fix the issue?
Many Thanks
