Vray Rendering in Sketch up 2016

Hi there, I’m facing abit of a problem with my rendering in Sketch up. I’ve been rendering my projects just fine but for one of my model, when I click render, it loads for awhile and does not render.

Its weird because im working on two files simultaneously, one renders just fine another cant seem to even render.

My frame will come up empty. I’ve tried a few ways and nothing still seems to come out.
