unity3d - Why does Unity does not import materials of .DAE file? -

i'm trying upload dae file (exported sketchup) unity3d.

it imports meshes, of them grey. guess imports materials too, materials become grey or something. here pictures of mean :

sketchup : enter image description here

unity : enter image description here

how can import materials colors (or textures) ?

if check mesh import settings on model imported in unity3d you'll see there option generate materials based on in mesh file.

see this page on official documentation around importing models , materials , assigning textures materials.
