Can any one help me please ?

Looks like something with your Scalability Settings. Try to “Build” your lights first. If it doesn’t work, check your quality settings.

You can also start the game, open the console (tilde) and type this command

Thx it was actually a problem specific to the kite demo, a left over BP who was managing Post Process parameters.

look for time Day BP and delete it
