Description

Running the console command "Show Collision" when lights are placed in the scene with "Visibility" off results in the lights turning back on.

 

Tested in: 4.22.3 CL#7053642 , 4.24.P4 CL#10387632, 4.25 CL#10479005

Steps to Reproduce
  1. Create blueprint project
  2. Add a bright light into the scene
  3. Set the lights 'Visibility' to false (uncheck).
  4. Press Play
  5. Run the "show collision" console command

 Alternative steps

  1. Open any project
  2. Create new level
  3. Add light to level if one not already there
  4. Adjust light intensity and color so it is obvious the light is on or off
  5. Check 'Actor Hidden In Game' on the light's properties
  6. Press Play
  7. Run the "show collision" console command
  8. Actor Hidden Game becomes unchecked during Play and light turns on

Result: The light is turned on

Expected: The light to remain off
