Hi everyone of CGSociety,
I’m back for a touchy question.
Does anyone know how to render on Max the VrayZdepth layer or image without having to recalculate my whole image or animation ?
Or in a way, am I obliged to calculate the RGB image to have the Zdepth image ?
Thanks to everyone for some clue.
Nono.

As far as I understand all the render elements are derived from the main render, not calculated seperately, so I think you’re out of luck.
Well if the render times is a problem, there is a trick, you can turn off all lights and disable indirect illumination then render it again with Vrayzdepth Element Layer enabled, it will be a lot quicker because the render will be very dark, but it will create the zdepth pass…hope this helps
