Help.. Is there a way to minimize the amount of white noise

on a piece of glass when is up against a solid material. I am doing a exterior facade rendering with lots of glass, rendering looks fine, but the sun hitting the glass reflects all this white noise up against the floor. I played with the nd, lowers the noise but the reflections are gone.

thanks

Can you show a render?

The noise you're seeing is reflected caustics from the sun bouncing off of reflective surfaces. It just takes more time to clear up unfortunately. You could try to lower the reflectivity of the materials.

You can try switching off direct reflective and/or refractive caustics in the render options which will not render that caustic light.
