Rendering problems with vray in rhino 4

[Kaner65]

New to site and using vray for rhino 4.

 

Whenever I setup rendering using basically the default settings, it will render for about half hour or more then crash. I'm rendering an ext. scene with pixel ratio of 2200 x 4400 (11x22 @ 200dpi)

 

using

irr. map

and light cache.

 

Has anyone ever had this problems or possible solutions/techinques. oh, also using windows 7 64bit.

I had this problem when I was rendering on the boot camp partition of my Macbook. I got sick of it and built a PC that has yet to not complete a job. My guess would be the view (with materials I am guessing) is too much for your computer rather than a problem with Vray itself. What are your specs?

I've experienced this issue before, and it did indeed come down to the hardware. That's a fairly high resolution, and if you're scene is fairly complex that will complicate things as well. There were 2 things I was able to do to work around this: I noticed that since rhino is nurbs based, one of the first steps it takes at render time is that it creates "render meshes." I did some research about this and was able to determine that it creates the meshes for temporary use while rendering. You can actually select everything in your scene, and export the render meshes before rendering. Save the meshes into a separate file, then open that file and render there. This solution worked for me, but the other thing I did to optimize the rendering is break the scene up and render different parts separately.
