Vray , problem with render, materials , glass

Hello everyone, I hope to receive some advice what is happening with my renders. I have applied materials in a model using vray , but none of this materials look real. The glass does not look like transpartent and with glossiness, Also laminate looks poor like material from sketchup. The glass using Windows Builder Pluging in render is grey , but in sketcup looks transparent. The quality of render is very bad, but I changed parametrs to get better quality. After all it does look far away that it should look…

It is impossible to say without seeing the model, but I would recommend using an appropriate V-Ray supplied glass material. This looks almost like there is bump or displacement involved.

Thanks a lot for a reply! I used a Vray supòrted glass material, all of them is Glass cristal transparent.
