VFB A/B option to compare renders

Hi,

Does anyone know how to use the VFB A/B option so that i can compare renders in vray. the option in my vfb seems to be greyed out and i cannot click on it.

Thanks in advance.

@Shawn,

at the lower bar of your VFB window, click on the litle “H” to show the VFB History Window. Then Render your first image (A) and click on Save button in the History window. When your first image it appears in that list, click on the “Set A” button. Now do the same steps with a second image to get B. Now the AB buttons are active in VFB.

btw. if the images are rendered already you can also load them using the Load button in the history window.
