vrayfur 64bit difference in animation

so I have animated the length parameter on a couble of vrayfur objects and when I render on a 32 bit machine the animation appears normal

But when I render the same file on a 64bit machine the animation seems to be skipped and the vray fur pops to its final length at the frame where the last key was set.

has anyone seen something like this?

thanks,

V Miller

Let me try and do a test here with this…

Best regards,
