The problem is that the Light’s are diffrent beetwen Ediot and PIE. To better show the problem I marked with Red Color the problematic area in PIE.
1)The Floor/Walls are Static.
2)No Dynamic or Stationary Lighting.
3)PP Unbound and Min/Max Brightnese set to same Value (1.2), this should disablesable AutoExposure ?
4)Only Spotlights in scene now ( No LightSource or SkyLight)
5)Emmisive boost global 0
6)No Reflection Captures
Thank You for Your interest!
