I have this obj starting with:
mtllib HogwartsOBJ.mtl
and the mtl has all the textures like this:
newmtl c69dd250_dds
    Ns 10.0000
    Ni 1.5000
    d 1.0000
    Tr 0.0000
    Tf 1.0000 1.0000 1.0000 
    illum 2
    Ka 0.0000 0.0000 0.0000
    Kd 0.7000 0.7000 0.7000
    Ks 0.1000 0.1000 0.1000
    Ke 0.0000 0.0000 0.0000
    map_Ka /texturasbmp/c69dd250.bmp
    map_Kd /texturasbmp/c69dd250.bmp
and those textures are there C:\Users\Dani\Desktop\harry\Otros Assets\Hogwarts3D\Hogwarts3D\texturasbmp and the obj is in C:\Users\Dani\Desktop\harry\Otros Assets\Hogwarts3D\Hogwarts3D\
but blender doesn't import it
                        
put render mode instead of solid
