Why is my directional light icon red ?


My directional light and sphere reflection capture icons appear red for some reason.
Both the lighting and the reflections seem to be working fine, I was just wondering why the icons are red.


When something is transform locked, its sprite icon will turn red.
To lock transform on an actor, right click on it → Transform → Lock Actor Transform.
The sprite color may not update immediately. If so, save and reopen the level to see the change.
