Vray noise on glossy surface

[Tze Czia Ti]

hi, I'm having this problem, noise on glossy reflection, and there is no 'treat glossy rays as GI' setting

I would recommend to reset all settings to default.  Your Max sampling are very low, for any interior scene you should not use less than 20 or so, this is if you have plenty of light, from your screen shot it seems is pretty dark.

Also those elements in the top, check your smooth groups and normals, it seems the messy geometry may cause those dark splotches.

Now you are also using low settings in your Irradiance map, that also may cause those dark spots. I would recommend using defaults, with Brute force instead.
