Vray plane light instances inconsistent

[vanderloo]

I'm working on an interior kitchen and I have vray plane lights instanced in the 3 windows on the left and can't figure out why the back 2 are much brighter on the ceiling than the one above the sink. They all have the same settings and same placement in reference to the windows.
I also have a dome light with a vray HDRI map but turning that on or off makes no difference.
What should I look for?
Thank You

What should I look for?

Is the glass the same in each of the three windows?

[vanderloo]

That was the first thing I checked. Yes it is Dan.

OK second try, have you enabled the Skylight portal option ?

[vanderloo]

Just tried that Tashko and now there is no light at all on the ceilings.

[tashko.zashev]

Is there any chance to attache the scene file (could be only pert of it) or send it to support at chaosgroup.com for investigation?

[vanderloo]

Yes Tashko. I'm archiving it now. Is there some sort of reference I should put in the subject line so you'll know to look for it?

Adding a link to this thread in the mail body is enough. Thank you.
