I'm just getting started with Blender. A friend of mine is helping me with this. He works with it, and since it's a lot of work, the

comes to the rescue. I know. To open an OBJ file in Blender in the main menu, you must first click "File," then "Import," and then "Wavefont (.obj)." In the dialog box that opens, you must specify the OBJ file you want and click "Import OBJ." But to display textures besides polygons, it is necessary that the paths to the MTL file are correct in the OBJ file, and in the MTL file, the paths to the pictures are correct.
