How do you make Vray work

How do you make Vray work. I have downloaded the demo version, pressed F10 and did the common thingy.

but It still wont work, what have I did wrong…cheers

It could well be that the version you have has expired.

I just downloaded the demo version today from this site.

Then still it could be expired, the demo is not automatically refreshed when it expires, at least not back then when I was using the demo.

most people think its a 30 day trial from the day you install it. however its not a 3d trial in that sence. instead its a dated timebomb. it will expire on a certain date (hehe and dont try to change the clock on your computer they figured out how to get around that one a while back)

it won’t render? or it renders black? assuming you set vray as the current renderer?

when the demo times out, you’re still able to select it as your renderer, but when you try and actually render something, you get a dialog box that states that particular version of the demo has expired and to check the website for an update. Seems pretty self-explanitory to me, but obviously not…
