Why does my material look better BEFORE it's rendered?

Hello guys, one thing that is really bothering me is, as you can see on image below, my cloth material looks better before it finishes the render.

Before rendering, it looks like the material on the preview, but after it renders, it loses the shine that I wanted.

Vray 4.2 for sketchup.

Thanks!

Because of lack of post?

It looks like it is not rendered fully, or with low settings, can you post render settings ? Result is like it is saved at the beginning of progressive rendering or something like that. Try turning off interactive and progressive rendering, and set irradiance map + light cache under global illumination, CPU rendering.
