Viewport turn black with vray lights

[aggster]

Hi everyone.

 

I have a problem with 3ds max 2010 64-bit and VRay 2.00.02. My grafic driver are Direct 3D 9.0 (Nvida Quadro 600).

 

The problem is in the perspective viewport when I use Vray lights. It all turn black (as in no lights, only black and grey) when I for example hit ctrl+z or when I flip ctrl+w to maximize viewport. I can however use ctrl+l to switch on default lightning to see lights in my scen but that doesn't solv the problem.

 

When the perspective viewport is black (after hiting ctrl+z, even if the ctrl+z doesn't have anything to do with the lightning) I can click in the perspective viewport and that makes it go back to normal vray lightning. But I have to click in the viewport every single time to make it work. Any suggestions?

 

This problem doesn't affect my renderings - that part works fine!

 

I'm not sure if this problem are caused by 3ds, vray or my grafic driver. But my suggestions are on vray.

 

Thanks!
