Gensky too bright

Why is it that when I use gensky, my scene gets blown out - the light is way
to bright?
Is it the skyfunc that is blasting the scene or is it the sun?
Gensky is my only light source.
When I render, the scene is almost all white - a few grays in shadow areas.
I have a rif with exposure set to 1
I'm also using -av .1 .1 .1 - is that redundant with skyfunc?

Thanks

Below is pertinent information

I was expecting someone to answer this by now...

The sky is not too bright, you just need to readjust your exposure to outdoor conditions. It's like shooting with a camera, you can't expect the same f-stop and shutter speed to work in your basement as in your back yard.

An ambient level close to what is recommended in the gensky output is appropriate. Your output recommends 13.1, so add a line "render= -av 13.1 13.1 13.1" to your rad input file for outdoor views. The exposure level corresponding to this is 0.5/13.1, or EXPOS=0.04.

Give it a try.
