Unreal Emissive Material cannot use for Cove Lighting


May I know why my emissive light material doesn’t show effect when i see from bottom. i can only see effect when i directly see the emissive light object.

It’s just because Lumen is still screen space rendering. I suggest use cubes instead of planes.

thanks!

Hmmm… be sure to check the emissive geometry is a static mesh and not a dynamic mesh. This may come from here too.
