Importing Rhino (.3dm) as object texture issue

[Figdor]

Hey guys. I'm importing a Rhinoceros model (.3dm) as an object for Archicad. Geometry is fine. But when I override the surface texture in the object definitions, the 3D texture is shown at a very small scale.

I would also like to ask if it is possible to configure more than one material for these imported objects (in Rhinoceros they are separated by layers).

thanks in advance
