The bug was resolved as a non-issue. The assets stick around because they haven't been garbage collected, but they won't be saved in the map.
Below are the suggested steps to follow: - Build lighting - Look at the number of lightmaps - Rotate your light source, - Rebuild lighting - Reload the map - Look at the number of lightmaps
Lightmap sizes seem inconsistent after rotating a light source and rebuilding the lighting. This causes concern about file sizes when packaging the project that is using baked static lighting.
The licensee is reporting their lightmaps are generating two times the amount of lightmaps after rotating a light source in their scene. One of their engineers edited a coupe lines of code to fix the issue on their end.
I have added some screenshots to show the differences between building lighting as well as the fix the licensees would like to implement.
Tested in main 4.9 - 2607310

1. Create new blank project without starter content.
2. In the empty level, drag some basic shapes into the scene.
3. Open the 'World Settings' tab and check the 'Force No Precomputed Lighting' to clear the lightmaps from the level.
Note You will need to build the lighting a few times for the number of lightmaps to reach zero. This seems irregular and possibly related.
4. Once the Lightmaps are clear, rotate your directional light source and uncheck the 'Force No Precomputed Lighting' and rebuild the lighting.
5. Rotate the light source one more time and rebuild the lighting.
Outcome: The number of lightmaps increases in size after rotating the light source and rebuilding the lighting. It only happens after the first rotation and does not continue to increase.
Expected: After rotating the light source, the lightmaps do not change in size until adding other objects to the scene.
i have this problem UE4CC-Windows-58DC12AF4B97F057BD108FBFF569B2E9_0000
I am not able to find world outliner how to enable it?
Undefined sysmbol: typeinfo for AActor when cross-compile linux dedicated server on windows
Delay nodes occasionally don't fire the "Completed" output in a nativized build
I can't open my map from the editor.
When I open UE4 4.24.3 it appears that. Does anyone know how to solve?
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-18244 in the post.
