I HAVE RUN THE DEMO FOR MAX 5 AND VIZ 4 (VERY IMPRESSED WITH DEMO) I HAVE JUST BOUGHT & INSTALLED MAX 6 VERSION OF VRAY.
I HAVE NOT AUTHORIZED IT YET BUT ALSO CANNOT ACCESS ANY OF THE CONTOLS FOR GI, LIGHTING, RENDERING QUALITY ECT… ALL I SEE WHEN I CLICK ON THE RENDER BOX IS A NICE CHAOS LOGO-BUT NOTHING ELSO COMES UP. IS THIS NORMAL?
ALSO THE RENDERING LOOKS LIKE 16 BIT IMAGE-NOT VERY GOOD.
PLEASE ANYONE-ANSWER SOON. PUZZELED
YOU’LL NEED TO AUTHORIZE IT FOR IT TO WORK 
no need to shout, we can hear you
You need to send us an authorization request so that we can send you a code for VRay. Once you enter the code in the authorization dialog, you will be able to access the parameters of VRay and your renderings will look normal. It may take some time until you get the code (usually within 24 hours); if you sent us an email and still didn’t get an answer, feel free to send me a private message and we’ll sort it out.
Best regards,
Vlado
