Test render outdoor scene: Vray 5/Rhino 7.
Why does the rendered scene contemplate the blue of the sky, but the saved image (png file) erases the sky and sets a white background?
Could someone help me? maybe in the Vray panel you need to set something?
Try saving as a JPEG.
For PNG you need a dome light.

I’ll try, thanks. 
I forgot to ask if you have dropped a Vray sky texture in the environment>background texture slot (it’s on the page with camera, render output, etc) and set up Rhino Document Sun?

Two other ways:
-
use the free image browser XnView - you can enable/disable the alpha of a png and remove the alpha, so that the background is visible again
-
in V-Ray you can set an output path and disable the alpha, but all images will have the same name.

It’s a pity that the developers was not able to allow to simple render without alpha, I miss it often too.
Saving from VFB manually will always output an alpha channel. It is a separate component, and it currently has no option to not write the alpha out. RenderOutput is the only way to remove the alpha
Thank you all.
I checked in the Vray 5 control panel.
I can’t see all those options regarding the alpha channel:

“Image option”, where is?
you have to put a file name. The file name extension will determine the kind of the additional options to show

Ok. Perfect! 
Hi, just started this account to ask you on thing. I have downloaded the XnView and enabled the alpha chanel. How do I save the image (in png) with the alpha on?
I hope I’m not too late haha
