About Sketchup file import to Rhino 6.4

Why is there no material assign on the model, only plain mash model, when I import Sketchup file to Rhino 6.4?

what format are you exporting/ importing? If .stl there will be no color info, if .obj you have to save the textures out and make sure the .mtl file is available

Attach the skp file you have problems with.
