V Ray background

Setting the GI and Reflection in Environment to TexAColor and white, I still get a grey background.
Is there some other control I’m missing?
I have background set to white in Appearance > Colors in Options and the same in the Shaded Display settings.

Thanks for any advice you can give.

The one that controls the background seen in the frame buffer is the one circled in red below…

Looking at your posted image, it doesn’t look like that is from the frame buffer.

So maybe it’s to do with the settings here…

It’s frustrating. I have everything set to white - the environment controls in V-Ray, the settings in the View > Display Modes, the Background slot in Appearances > Colors. All set to white. But I still get grey and my client wants white.

I hate how often I have to bail out to SketchUp to get decent graphic output.

Ok, my last guess…are you using the physical camera exposure? If you get that wrong then it could come out grey.
Maybe use the colour correction curve to increase the gamma?
Or your very last option would be to render it out with an alpha channel, save as a png and then use photoshop for the white background.

Thanks for your input. I turned off physical camera and that reduced the grey to a very, very light grey, not white but close. Not sure why that is. I’ll have to research it after I get this project delivered.

But whatever the reason - I’m back in business now thanks to your ideas.

You won’t be able to get pure white in a render that tries to replicate the real world, unless the object is blownout.
You’ll have to use a material wrapper or assign an alpha of -1 to the material of the backround.
