Overcast is working fine for me. http://imgur.com/a/2ZJYw

Fadi - good for you.

Try setting cloud quality on ultra.

Ultra quality is not an option for my rig, but different configurations it randomly gives me result of "clear sky" to "little cloudy day" - never full overcast.

@demicanadian
How are you setting the rain and overcast values?

Possibly related to #3567

I'm using the editor. Updated description with that info.

If the problem is that the sky is never overcast at certain settings, that's pretty relevent information that probably should have been stated in the ticket description/summary.

You should update the summary title and description to mention that.

@Gugla - if you need any info, hardware info, reports or logs, just tell and I'll try to help.

Thanks Demicanadian, I will check it
