Sun Noise not clearing

I am having problems with noise...
On the images below, note that the "sun" is causing some noise on the floor and wall.
With the sun turned off, the rendering is mostly clear (for my needs).
I can't figure our why. Any suggestions? Tks!
(I am just using Physical Sky)
No Sun (Sky only):

Is this a merged MXI from a network render?

Yes.
4 nodes that are right next to me.

Then I think it's because of a merging bug with network rendering that make these dots appear, even though they are not in the individual MXI files. It's fixed for the 2.7 update though which will be out very soon.

In the meantime, you can try HDR environment instead of sun and sky. I haven't had any trouble with fireflies/merging, using it.

Sorry for hijacking your thread gtalarico, but since you've mentioned HDRi, Brian - is it possible to get
really sharp shadows +
caustics when using HDRi?

Maybe with the right HDRI.

Great.
Bubbaloo: If my maxwell skills only allowed me... : )
I haven't been able to get hard shadows without using the physical sun....

oh yeah. looking forward to it!
I had to avoid this once by composing the different lights in photoshop (linear dodge) and applying "remove dust and scratches". But doesn't give the perfect result.
