Thanks now it shows on my screen but there is a problem, I see two kinds of doors and house one that has no material name on it and the other one with the materials assigned.

I checked my material names on blender and it is indeed needed to be assigned on the cr2 as you have shown but why are the bones misplaced?

Can you give me some links or tutorial about cr2? does it mean you have to manually edit all your created cr2 from ds4?

I tried to follow what you said and redid the first part of the cr2 but after loading it when I tried to rotate the door it is off center and bones were also not placed properly even though I placed them right.
