Vray RT rendering black with circular lights

[johannpascual]

Hello, people!

 

I have a problem with RT rendering. The regular renders are fine, except for RT. Here's what the RT render looks like...

 

 

 

I don't know what's wrong. My specs are:

 

Windows 7 Ultimate

SketchUp Pro 2013

Vray v2.0 SP1

GTX 770 2GB

 

I didn't touch anything in the RTEngine options... I just enabled it. It's the same even if I use CPU or CUDA. Although I tried turning GI on and off and other stuff and it's still like that. I tried this on another Windows 7 Pro computer and it's the same thing. But I tried it on 2 other Mac computers and it's all fine.

 

Please help.
