Re: Glitter in the reflection?
The glitter gets bigger the more you zoom out from the object.

Re: Glitter in the reflection?
I am still working on this issue. I have tried Highlights & FG, Interpolate, Single sample in the Arch Design dialog box. No luck. The only way it goes away is to up the samples to 64/256. Render time too much to be of production value. Any ideas? I will try 'em.

Re: Glitter in the reflection?
for me looks like a samples problem, not antialising, kick the samples in your metal around 128 or more and see how this work, if you are hitting to high samples (around 500) try lower them but with interpolation on. Mental ray always has problem with blurry materials. HOTCHIP develop this material script that really speed up the blurry reflections in Mental Ray and other problems

If you are using an HDRI as illumination source the noise in the reflection or blurry reflection is bigger, try to blurry your HDR image that should work

Re: Glitter in the reflection?
@fco3D - your right, upping the samples makes it all go away...but makes the render so long that it has no production value (i want to churn these things out). If I move the HDRI, the glitter appears somewhere else. I will try the blurring of the HDRI. Thanks for the help.
