I've searched all over and have never gotten any help on this. I posted to Autodesk, and in The Area and got my posts deleted about this. I don't know why.
I own 6 and 2009 and both tend to crash while trying to animate Lens Effect Flare properties. I can animate them in the VP window but when I click ok after I get what I want Max freezes and I have to restart it. I can never get a property to render. I've tried the usual, changing from Direct 3D to Open Gl to Software but still no dice.
I've seen posts where people have similar problems but there is never a solution. I really like what possibilities could come from VP but can't get it done.
