Urgent:Vray Clamping Renders

[michae]

Hi,

So Im having a big issue where all my renders are being clamped. When I sample colors in the frame buffer it shows them well over a value of 1. When I use exposure correction and lower the exposure I get whats expected with a 8 bit image and the opposite when raising the exposure it acts like a floating point image. When I save out the images from the frame buffer or through batch render they are clamped at 1. Just a few details: clamping is not turned on in settings, we are using exrs with default compression. I attached a basic scene with the issue.

Click on the histogram toggle in the lower VFB tool to enable and then disable the histogram control and it will be fine. In any case, it's a bug and will be fixed.

This is becoming a bit of an issue for us, that solution works sometimes but the bug happens when we batch randomly . Do i need to turn it on then off again then save before sending out a render job ? Is there a command line script that that could do it?

Thanks

There is no script for this unfortunately. This will be fixed for the next night build on Monday, but for the time being a solution could be to use the stable builds, which don't shave this problem.
