Render problem with vray

Hey guys,

alright, so I encountered this problem with my iPhone final render with vray.

I've got the Apple logo and some text on the back of the phone as a texture.. on top of it, there's a thin glass plate. The problem is, when I do the render, the texture doesn't show up.
It is visible in the viewport, also in the active shade render. Even in the prod. render, but only up to the point where it's calculating GI. I am not sure what the problem is, since I am very new to V ray. I figured out, something must be wrong with the glass cover on top of the actual thing, because when I hide it and render, the logo is visible and everything is alright.

Here's a screenshot too:

I'd really appreciate any suggestion on how to fix this problem


//and for those wondering, ye it is from Ben Tates tutorial on cg tuts

It's strange. Could you show a screenshot of the shader that has the logo? It would be easier to understand.

Here are both the material and the actual map from diffuse:

If you need any more stuff to clarify the problem, just say

If i understand correctly the thin glass layer on top is a separate object?

Could it be that the problem is lies with this glass layer?

Does it render correctly if you hide the glass?

If the glass layer is a different mesh like CHRiTTeR said, try to uncheck "cast shadow" in the properties of the glass.

Tell me if it works.

There is a switch in the Vray material properties, in the Refract section, called "Affect Shadows", make sure it is ON (it's off by default).

With the switch off, transparent materials (i.e. have a refractive amount), will cast solid black shadows, with it on the glass transparent object will cast appropriately less solid shadows.

Ye, that solved the problem. Thanks a lot guys

Actucally, I feel like a noob now, as the solution was very simple. Only my Vray skills held me back.
