Arnold GPU - Area Lights don't work

Hi everybody!

I felt the need to open a new topic for this, because it didn't fit well in the one I have previously opened.

The area light not working, despite the documentation stating that they should work if I stick with the quad shape. It just does nothing and sometimes leads to a temporary freeze.

Thank you very much for any help or advice! ;-)

@Mauro Sanna Don't worry about opening new topics. It's better for us to have one question at a time, so one topic per question is totally ok.

Update.

I have changed the renderer from CPU to GPU with the render view closed (though the render was not started, so I was not rendering), and now, if that was the cause, it's working fine with a sphere and a plane.

I will try with the more complex scene later on.

I'll do it with a simple scene (a sphere and a plane, plus one area light) and post the log here.

The area lights are working ok in my (simple) test scene.

Can you get an Arnold log (verbosity level = Info) ?
If you're using the Arnold Render View, select View > Log > Full first, so we get the whole log.
