Twin Motion - rhino

Hi All,

I am new to twinmotion.
when I import my model from rhino using rhino-twin motion plug-in, I want to apply to my building but materials apply to the whole building.
Like when I want to apply glass or concrete all the building becomes glass or concrete.

Can someone help me how to apply material to the building properly?
Also I can’t move - rotate or scale using the program. I only can do so from the Rhino.

Can someone help me ?
