Problem Vray and reflection glass

[nicksman24]

Hello everyone,

I ask your help. I'm using Sketchup + Vray
I have a problem in my image. The reflection of the light source in the glass produced lots of little points of light.
I have tried many settings but nothing works. Even lowering the noise greatly. The glass is a material Vray "clear_glass Archetectural".
Thank you in advance if you can help me.
