I have a scene. One object has material, it is the standard aluminum. No adjustments. For lights there is just one environment light. Rendering is standard mantra1 node, with pixel samples set to 5. No other adjustments.

Even though the gun is not moving, the material just sparkles. My guess is that there is a setting that would mitigate this. Would someone please point me in the right direction…

Thanks!

I'll give this a shot. Thanks!
