I've got diffuse/reflection/refraction quality at 10, and the indirect lighting node at sampling quality of 10, and I *still* get noise in the “indirect_reflect” channel, any more advice?

Also, do you have any advice for removing noise? I want to find settings for a multi-hour render I can do overnight with zero noise. I'm already up to 7x7 pixel samples and I don't know what else to do.

Thanks so much! That roughness suggestion was a great fix. And I like the “box” primitive with group-numbers used for material assignment, thanks!

Anybody have success making the workstation beep when a render completes?
I tried the following script which works in Terminal/Python, but when I paste it in the post-render script (with type “Python”), I don't hear a beep.
import os; os.system(“echo ‘\a’”)

I'm rendering this “cornell room” type of scene, and I've got render noise under control for the most part, but there are some specific image planes where I've got some weird things going on.
My scene is a cube room with white walls, an area light up top, and 2 spheres. The spheres are using built-in materials for Glass and Silver.
Composite result (mostly fine). The Indirect Diffuse was also fine, not including it here.
Direct diffuse - what is with the rectangle of noise?
Direct reflect - why is the glass reflection all noisy, when the silver one is fine?
Direct refract - why is this pitch black? Is that normal?
Indirect Reflect - again, the glass just seems noisy for some reason.
Indirect Refract - Oddly, this pass is NOT noisy even though the direct one was.
Direct Samples - Huge rectangular artifacts. Not sure why.
Indirect Samples - Also has some rectangular artifacts.

Houdini Indie and Apprentice » "Render Region"

I like the “Render Region” concept from the tutorials. I have setup a render that looks fine in the Render view, but when I go to the Scene view, and I've got the correct camera selected, I draw the “Render Region” rectangle, press render, and nothing happens. Any ideas? Follow up: Why can't I use the “region” approach with the Render View itself?
Side question: I want to decrease the render resolution to speed up renders. My camera is at 1280x720. I edit the Mantra Node and click “Controls”, choose “1/4 resolution”, and press Render, but the resolution is not decreased. The only way I seem to be able to decrease resolution is to set it on the camera itself. What am I doing wrong?

Out of desperation, has anybody had any luck dual-booting their Mac into Linux and finding more stability there?
Is this a hardware or software issue?

I have an iMac 5K with 10.10.5 on it, and Houdini fails to install with “The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance”). I submitted a bug over a week ago.
Anybody else having problems on iMac's, or 10.10.* ?
