Transparent background


Recommended Posts



Can someone help me. I try to figure out how to make a transparent background to an image file in V-Ray. I know how to do it in renderzone.

I've got some weird result with V-Ray so I'm not sure if there is a bug or is it just my incompetence.  :D

Windows or Mac?


I say that because when I save a PNG image out of the VFB in Windows, it has a transparent background.  I don't think this is what you really want, but just sharing.  I think this is a bug, but it's the way it works right now.


I believe you want to use the Render Elements in the Vray settings palette.  You can save various 'render channels' to separate files or even the same file for post production work.  The VFB is really powerful.  More info here - https://docs.chaosgroup.com/display/VRAYSKETCHUP/V-Ray+Frame+Buffer+%7C+VFB

Make your plane roughly the proportions that your image has.

(Maybe it helps to make the alpha a bit bigger and center the Logo in it)

Then you can scale the object with the texture.

Use edit texture and set "proportions" to (your image) , finally adjust the segments using interactive display.
