help with vray

[abhinavvishak]

hey guys, Im relatively new to vray, and while following a youtube tutorial, came up with a problem while rendering a scene .

 

i was trying to render some object using textures from www.vray-materials.de ( specifically a type of granite slab called calacatta )

 

while Vray was able to render 'standard primitive' boxes properly and accurately , i was unable to render a 'box' which i created by making a closed spline using lines and extruding it ( only a solid color renders, without the map )

 

Is there any setting or lighting issue that i have missed . waiting for you responses

 

If i was not clear with my question , please do comment ill give any other information you need
