Rendering doesn't work when I import Rhino object

[Paopao]

Archicad cinerender doesn't load or freezes whenever I import a rhino or 3ds model: it is a quite complex model but it does seem to be imported just fine into archicad. The problems is that I cannot launch the rendering engine as it freezes or gets stuck. Any idea why is this happening?

Thanks

What happens when you convert the object into a morph?

I haven't tried. I am going to do it and let you know. Thanks 
