Actor Hidden In Game for rendering

Been using this feature in 4.10 fine. The purpose is to use emissive cards to light levels.
Repro:

  • Create a material with emissive material assign to a static mesh, place in scene.
  • “Use Emissive for Static Light” = True in details of
    static mesh
  • Under Rendering tab of a static mesh “Visible” = True
  • “Actor Hidden in Game” = True
  • Expected result is the emissive cards would be
    used to light the scene while hidden
    in game.
  • Bake lighting
  • Current results, the cards are invisible to the light build. If “Actor Hidden IN Game” = False, they will now contribute to lighting.

I presume you want the shadow to be baked, but not have the mesh visible.
For that, use “Cast Hidden Shadow” instead.
