Hi …
… is VRay working along with Max Video Post Effects? … No matter what I try to set up … I can’t get any previews of Video Post effects …

No helping hand out there … ?
** BUMP **
I don’t think they work currently. Last time I tried Render effects while working on an animation it crashed max when rendering.

ummm… nevermind, I just checked and they seem to work fine.
which version of vray and max are you using?
--Jon
Still not working …
I’m using Max R5.1 and VRay V1.09.03b … Preview in Video Post isn’t working at all (Glow) and when I start the Video Post Renderer Max crashes … hmmm … very strange …
Maybe u have a small test scene that you can send me …
