I have a cityscape 3d model that is in .obj format. When I import it into Blender, it does not import the .jpg texture files. Is there any way that I can import the textures manually? Any help would be appreciated.
You could try to convert the .obj file in a different format.
To load images as textures I used that plugin: https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Add_Mesh/Planes_from_Images
