Sketchup / Vray - Light+Shadow rendering problem

Hi,

I'm somewhat of a vray rendering noob. I've modelled a scene which I'm now trying to render, but I'm not getting anything near the results I'd expected. I've tried googling the issue but can find no obvious solution and outcomes have not differed greatly despite my tinkering with the settings.

Basically I'm trying to render a scene which is set on the top of my builing; I've created a large number of objects on top of a frame I've designed to simulate the light and shadow effect of light passing though foliage - the unrendered scene shows the light/shadow that I want but when I render I get a scene with apparently no light, or at the very least no light/shadow detail.

The render I have shown in image 2 is using default settings.

Could someone advise me please?

Will

Thats not really helpful..

I have rendered in vray before, and although I'm not an expert I don't think I should be getting a result so removed from my preview in the unrendered view.

Trawling through general tutorials is of no use; can anyone with specific knowledge actually tell me why this is happening? And if possible, offer some advice on how to resolve the actual problem please?

you can also post this problem to vray for su tutorial section.....or ask permission to sir nomeradona to send him a personal message whenever you have a problem regarding sketchup and vray...im sure that he can answer your question regarding this one.....or try to set to check if you GI map is set to sky....if not try to change it...
