vray 3.20.03 problems loading old scene with exposure

[Karonte]

Hi all, i have a small(big) problem. afrer installing Vray 3.20.00 my renders are "different" from the old ones.
After searching for the reason, i found that something has been changed in VraFrambuffer. If i enabled, in old renderings, Exposure and change Contrast and highlight, rendering are very different.
This is a big problem because if i want to use an old scene the result is different. Please help.

The contrast function was changed. The new one preserves the black and the white points of the image, and is generally more pleasing. If you need to reproduce the old image exactly, there's unfortunately no other way except to render it with the old build.

Best regards,
