Glaag,
Twinmotion synchronises directly with Archicad, it is quite seamless. Hopefully EPIC will implement Ray-trace and some further controls to improve the output quality (I personally find twinmotion a little too ‘gamey’ for imaging, great for videos though, and renders at speeds any other rendering package could only dream of) to make it a more complete package. It is hard to beat for speed, not to mention you only need an hour to learn everything you need to know.
Exciting news!
