I've been having similar problems. I think mine have been caused by
"flagging" my objects (in the editing menu) incorrectly. Don't know if
this will help you at all.
I had some objects that I wanted to have reflection, refraction and
transparency all together. I flagged "front" and "reverse" and
"transparency" on some single-sided objects modelled in TAV 4.3.
Oddly enough, I seemed to get the best results by removing all of
those flags. Evidently IPR knows that if it is going to reflect and
refract, it's going to be transparent. It also seems to know which
sides are going to be visible, although I'm not sure how.
My problem is that I was hoping to dissolve my refracting objects in
and out of the animation but it seems that this may be impossible,
short of rendering two seperate animations (one with the fading
objects, one without) and then combining them in composer.
I have a friend using Softimage and he says he can't get refractions
to dissolve out either.
If anyone out there knows a better way of animating a
reflecting/refracting object so that it dissolves completely, I'd
really appreciate it.
