V-Ray Clipper Problem

I have a problem with a file that I have 8 Clippers on and if they all are hidden or the Enabled box unchecked then I can render a 1080 frame at about 3 min. If I unhide or Enable them then that same frame goes to 31min. Is there a way to animate the enabled state of the V-rayClipper? Im beating my head on my desk as this is drastically slowing down my animation and I desperately need to get this thing rendered, the times above are on my 2990WX and the rest of the farm is 1hour to 3 hours per frame and I have about 2100 frames to render and after a week its at about 36% complete which is insane… Ive narrowed the bad render times to the clippers but cant figure out how to get them to render faster other than hiding them when I dont need them in the shot.

Just a shot in the dark - try moving the clippers far away. You can also send us the scene to see why is it that slow.

Thanks Peter, Im desperate for a better answer lol. I did try moving the clippers far behind the camera over a single frame but it only reduced the render times but a little bit like 5 or 10 min and would love to if I can get them back down to closer to 5 to 10 min to render the entire frame if possible. Ill shoot you an email soon with the file.

Cheers,
