difference IPR preview-final rendering

[matteo_speri]

hi, I'm publishing my first job, it's a test ..
I see a difference between the IPR preview and the final image; the render is much darker and the lights are not the same
(if I use photoshop I correct it), I don't understand if I'm wrong (I don't have any auto exposure settings)
thanks for the support
PS. i use Vray GPU

Better send the scene via the contact form so we can take a look. Address it to me in the subject and include a link to this thread in the message.

There doesn't seem to be any differences between the IPR and production renderings on my end. Which V-Ray build do you have installed?

hi, thanks for the support; I have installed version 1.3; in other files I don't have the same problem;
in the two images we see a different light between IPR and final render, especially on the floor and
on the ceiling chandelier and in the intensity of the reflections. But I try with other tests

Thanks,
Matteo

Try enabling the "GPU Light Cache" (Render Setup>V-Ray>Global Illumination) and see if that makes any difference.
