It is relatively simple to do an Archicad rendering with Artlantis.
They have a straight-forward plug-in to transfer data.
It is much faster and better than that lousy LightWorks.
You will remember my lack of love for LightWorks from our seminar together years ago.
And there's a great book to get you started with Artlantis.
Try the demo - fully functional but watermarked.
