In view of the fact that ArchiCAD 8.1, an ancient form of ArchiCAD known only to the Neanderthals and incapable of anything beyond mud huts, doesn't have the LightWorks rendering engine (introduced in ArchiCAD 9 and carried through with much disappointment almost as is for ArchiCAD 10) the answer is "no."
You must make it up in Photoshop.
BTW: this is the better practice in any event since the LightWorks method doesn't provide a preview and can consequently be cumbersome to employ.
