Invisible prims...

Has anyone noticed invisible prims seem to no longer render shiny prims invisible? Example: on my cars I use invisible prims to sculpt wheel wells so you can see the entire wheel through the prim. I hope someone understands what I mean. Now yes, I can see through the prim with the invisible script in it but it only cancels out the shiny part of the prim behind it and no longer the entire prim. Check out the attached pic. This will demonstrate what I mean.

This kills me, most of my cars utilize this. I love SL and I know stuff happens but HELP!!!

The effect of invisiprims on shiny has always been unpredictable. It depends on video card and driver versions, and no doubt many people always saw the effect you're seeing now.
