Hi,
I used vray 1.5 RC4 for a long time and now updated to the final release 1.50 with 3dsmax 9 SP2 on a Vista 64bit system.
Everything works fine except when I open older scenes with Vray as render (indeed in all scenes I have!!) 3dsmax crashes.
The only work arround is to merge the older scene and import the Vray settings (if saved).
So, what is wrong?
Is there a way to merge scene settings from a .max file too?
Does it crash immediately when you open the scene? In that case, try using OpenGL viewport driver and see if it helps. If yes, then it is an issue that is corrected for the service pack.
Best regards,
Vlado
Ok that’s the reason… now I only need SP1 … 
Hey I have this exact same issue with only one particular scene ! So every time I work on it I need to switch back to opengl mode.
Didn’t think a second that it could be related to vray though. Hopefully the SP1 will soon be here to correct that.
oh then my problem is solved too. 
i tought it’s something with Direct3D driver, now i switched back to OpenGL…
best regards
