pixelated rander

[yossishabo]

hi,

this is my first scene i try to render in Vray,

so after a few tries i could achive the result shown below.

first i would ask for some improvments for the scene.

and second and more important, there is a pixel problem in the bottom of the window, the silk and the light cast on the marbel near the silk.

the area looks very pixelated.

its a 640X480 if it metters but even when i took just that area in 1920X180 it is the same.

thanks ahade
