Talking Re: sky portal intensity

Are you saying they emit too much light, or that they are blown out visibly?

If the former, well, your exposure must be off.

If the latter, well, read on:

Here's the thing: Our eyes have built in tonemappers, and we are really poor at judging absolute intensity. So we can stand inside a room, lit only by light from outside the room (through a window) and see stuff both indoors and outdoors.

Try that with a camera; either your indoors are pitch black, or your windows are blown out. That's just life, with real photography.

Luckily, the portals have a built in feature to get around this unfortunate reality of physics: Go to the advanced rollout you'll see a "Transparency" setting. Set it to some dark color. This will not affect the light, only what you see through the portals. It's a faux trick to behave like your eyes - it makes the great outdoors darker to the camera, but still lets all of the lighting in.
