Thanks for the reports on the Lighting Scalability Manager. We’ve identified an issue in the LSM that caused the visibility/hidden state of the lighting components driven by the LSM to be inconsistent in previously saved maps. We have fixed this issue internally and it should be fixed in an upcoming release - unfortunately it missed the window for the next release.
Just to add some additional visibility to another lighting issue seen in the 28.30 update, we’ve also fixed an issue reported in this thread. That fix will also appear in an upcoming release.
Our hope is that these two fixes should resolve the various issues reported in this thread, but should you continue to encounter lighting issues, please reach out. Sorry for the trouble and thanks for your patience.
