Rendering Problem - dark renders

I have been trying to render an image with Vray 3.0 and Maya 2015. When I render through the viewport everything looks good but when I save the image it is really dark. It is also dark when I batch render it. I have got my gamma set to 2.20 but it doesn’t seem to want to save the corrected gamma.


Saved image ^


Screen captured viewport render ^


Render settings ^

Hope someone can help,
Thanks.

One of the images doesn’t show up (seems like the link is broken). What file format are you saving to?

Best regards,
Vlado
