Don't render final image with render pass

[Spip]

Hello,

I'm working on a student short film, and I would like to know how is it possible, in order to optimise render, to don't render final image but I need to use the Vray frame Buffer with Split render channels.

Can you help me ?

Thank you in advance

Anyome to help me ? VFB use only Ram and Not CPU ?

either im not understanding you or your missing some fundamental piece of render theory when it comes to rendering and using passes

Hum, in fact, I just want to know if is it possible to save with "split render channels" RGB, alpha, zdepth etc.. WITH the possibility to hide during render, the phase calculation in VFB in order to help CPU to calculate faster ? What do you think ?
(sorry for my english, I hope you understand)

Thank you in advance Da_elf

You can do this but i'm pretty sure it only saves RAM and wont help it render quicker.

For the sake of how to do it anyway, you want to render to .vrimg straight to disk with no preview.

Under the the Vray Frame Buffer tab, Turn off "Render to memory frame buffer" and turn on "Render to V-Ray image file" and "Generate Preview". It'll save the file as it renders it and then you just use the command line tool included with Vray to convert it from a vrimg to exr format.

I think you also need to set the resolution of your render in 3dsmax to 1,1 and set the real resolution in the vfb settings.
