Hi all,
i recongnized that in vray frame buffer, you can’t “judder” the lc forward.
its a pitty.. i love to judder lc. 
I might be able to help, being the Judderman and all…nope, on checking, I can’t
hehe
ok lets name it scrub, or what ever.
but is it possible to implement vlado?
Maybe it’s me - I still don’t get it. I think I know what judder is but I can’t deduce what that has to do with a light cache (lc?) and why/how I would want to do it forward.
hmm ja its more to play while whait on rendertime.
when sitting in front of lc calculation, in max render window, you can “Judd” the lc forward.
i mean you can force vray to update the visibility of the lc progress by scrub over the rendering with middle mouse button.
in vrfb it doesn’t work.
its a psycho-thing. and minor i know.
but i love it.
If you rotate the middle mouse button, zoom in then zoom out, doesn’t that do the same thing?
I have thought this, too, but never knew there was a name for it
have you tried to switch 1 second to another app with alt-tab and back to max ?
and you can see the same thing on the buckets for long (-3/0) IR calc.
