Transparent sides of Text (see-through material) in Xara3D ?

[Munenushi]

Sorry to trouble the forum with this; but I did a quick Search and could not find any information on whether it is possible to create 'Transparent sides' of the Text in Xara3D.

I am currently testing out the TRIAL and I am enjoying how simple it makes creating 3D models of Text!
I just cannot seem to find the controls to adjust the opacity of the sides of the text (to make them see-through).
Perhaps I am just missing it, somewhere...

Can Xara3D make transparent material?
Or is it something that a more expensive product of theirs might do (and not this one)?

Thanks for any information or guidance anyone can provide
