This bug is still in the Game since more than 6 Month. My hope was, that it will fixed togther with the other HDR related problems in the Game. (Like overbright in Buldings and Scopes).
Now you guys "Tweaked" this stuff, but the HDR PPE Problem is still present.

If you call a PPE effect from Script:

BaseWorld world = m_character.GetWorld();				
world.SetCameraPostProcessEffect(world.GetCurrentCameraId(), 17, PostProcessEffectType.HDR, NVG_EMAT);

and disable this effect later, the brightness of the screen will not reset.

BaseWorld world = m_character.GetWorld();	
world.SetCameraPostProcessEffect(world.GetCurrentCameraId(), 17, PostProcessEffectType.HDR, string.Empty);

I also tryed to reset the brightness with "world.SetCameraHDRbrightness" (float -1). But the Game does not care.
