Transparency - now you see it, now you see it.

I am recording an animation (with use of Photoworks) inwhichI use Tranparency in much of it.

When I look at the screen (unrendered), the items I have trasparentare not shown (yippee), but when I render it, the items that aresuppose to be unseen are now seen. This is what happens when Irecord too. What am I doing wrong, Isnt transparency supposed towork in Animation (with Photoworks) ??SolidworksMotion Studies
