problem rendering old scenes with vray 3.0

[davidhdz]

hello I have a problem rendering an interior scene that i made with vray 2.2 and max 2012 now I have vray 3.0 and max 2014 and i need to do the render again but when i render the scene it renders way too dark

does it has to be with settings or something like that?

i tried to merge it in a new scene and adjust the settings manually

i also checked the gamma and lut settings to match with the older file but nothing

 

i'd really appreciate any of your help

thanks!
