[RELEASED] for UE4: Complete Sky and Weather System

Hi.
I don’t understand how lighting works with your sky system.
With default settings and the “cumulus” default sequence, the sunlight is a 24 lux with a sunny weather which doesn’t make any sense as sunny weather sunlight should be between 32 000 to 120 000 lux. I thought that your system is “physically based” so it’s strange to see that default sunlight is set to such low lux value.

As the sunlight intensity can’t be set manualy because controlled by the plugin, I tryied to push the “Sun Multiplier” in the TrueSkySequenceActor until I can read a directional light intensity that makes sense (sun multiplier : 1500 = Directional light intensity : 36 000 lux). Is that ok?

Now the problem is that after setting the exposure, the sky is almost pure black because the skysphere (not the SkyLight component) does not emit enough light (of course, same with shadows because there’s almost no sky reflection. A chrome sphere in the scene is pure black too)

Then I need to know how to push the sky intensity and I’m lost.

  • The “brightness” setting in the TrueSkySequenceActor seems to be a general multiplier, so it change the DirectionalLight intensity too: wrong choice
  • I don’t know how the “Lighting” settings in the actor works as they are all greyed.
  • I tryied to look at the sky settings in the “cumulus” sequence but I can’t find anything about the sky. Trying to play with settings , even “atmospheric” settings leads to changes in the DirectionalLight intensity.
