Help with output size

[MJW]

Have always used Rhino for my CAAD work and so when VRay for Rhino came out I started to use it and try to do my own visualizations too.
However I am a novice when it comes to this.

My problem is rendering to a big enough size.
I need visualizations at A3 size
that is
297mm by 420
and with a high DPI <200> if possible

even using the VRay preset of v.high
I still can't achieve the results that I want, at the quality I want
I assume that I have to change something in the "Output" drop menu
I'm just not sure what....

Any advice would be grateful welcome
Am I being over ambitious?

Re: Help with output size

If you don't want to calculate the size, than open Photoshop and start a new document - set image size 297x420 mm and resolution 200. The new image is 3307x2339 - that's your size for the Vray output.

A VfR integrated DPI-size calculater at the output options could be nice.
