Vray Light Cache VS Prepass Lighting issue !!

[steevenberube]

Hi,

 

When I look at my preview running on light cache, my image looks just fine but when the prepasses kicks in, the image is all overexposed up until the final render. If I try to balance with camera exposure, a lots of area are too dark. What I am doing wrong? I hope you have enough information on my settings.

 

gamma/LUT correction is ON @ 2,2

 

thank you

The prepass generally isn't a very good indication of what the final render will look like. So it would be better for you to show us the final render. If the final image is overexposed my first guess is it has something to do with your dome light multiplier being set at 15. Try leaving it at 1 and setting the inverse gamma to something around 0.75.

 

Also, is your shutter speed at 1/2000s or 1/2s? If it's at 1/2s then it's off and you should look at something like this to set it correctly first.
