I just can't seem to get smooth visability-transitions in my motion studies. It looks great in the Open GL preview, but not when I take it out trough Photoworks.

I have tried hiding and changing transparency, none works smoothly. PV does it kind of nice first, but will not go smooth all the way to invisibility.

Have tried taking all reflections and such to zero, but PV cooperates not

I sadly saw a discussion from 2007 here, describing the same issue. Is there any workarounds?
