I'm having trouble with the area lights in a scene causing noise -- it's still in the early stages but all the other lights/shadows are pretty smooth. even cranking up samples, photons, radius', final gather's on etc.
I'm upping every parameter I can think of and all's that's happening is the render time is increasing...

I'm not too fussed about the weird shapes and angles that're created here; until I sort this noise out there's no point in continuing.
