Hi

I wrote a simple OBJ loader but the texcoords are messed up somehow. I can't figure out what is wrong. I tried flipping the texture on the Y-Axis, no success. (Here is how my object looks like: http://imgur.com/d8edSyw

Code: (FaceData holds the IDs for vertices, normals and texcoords, Vertex class holds the data)

public void parseObj(String path)
    {
        try {
            BufferedReader reader = new BufferedReader(new FileReader(new File("").getAbsolutePath() + "/res/" + path));

            String line = reader.readLine();

            while(line != null)
            {
                if(line.startsWith("v "))
                {
                    int start = line.indexOf(" ");
                    String sub = line.substring(start + 1);

                    String[] vertexStr = sub.split(" " );

                    pos.add(new Vector3f(Float.parseFloat(vertexStr[0]), Float.parseFloat(vertexStr[1]), Float.parseFloat(vertexStr[2])));
                }
                if(line.startsWith("vt "))
                {
                    int start = line.indexOf(" ");
                    String sub = line.substring(start + 1);

                    String[] vertexStr = sub.split(" " );

                    tex.add(new Vector2f(Float.parseFloat(vertexStr[0]), Float.parseFloat(vertexStr[1])));
                }
                if(line.startsWith("vn "))
                {
                    int start = line.indexOf(" ");
                    String sub = line.substring(start + 1);

                    String[] vertexStr = sub.split(" " );

                    norm.add(new Vector3f(Float.parseFloat(vertexStr[0]), Float.parseFloat(vertexStr[1]), Float.parseFloat(vertexStr[2])));
                }
                if(line.startsWith("f "))
                {
                    int start = line.indexOf(" ");
                    String sub = line.substring(start + 1);

                    String[] vertexStr = sub.split(" ");

                    for(int i = 0; i < vertexStr.length; i++)
                    {
                        String verStr = vertexStr[i].replaceAll("//", "/0/");

                        String[] asd = verStr.split("/");

                        FaceData data = new FaceData();
                        data.vertexID = Integer.parseInt(asd[0]);

                        data.texID = Integer.parseInt(asd[1]);

                        data.normalID = Integer.parseInt(asd[2]);

                        faces.add(data);
                    }
                }

                line = reader.readLine();
            }

            reader.close();

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        for(int i = 0; i < faces.size(); i++)
        {
            Vertex v = new Vertex();
            v.pos = pos.get(faces.get(i).vertexID - 1);

            if(faces.get(i).texID != 0)
            {
                Vector2f t = new Vector2f();
                t = tex.get(faces.get(i).texID - 1);
                t.y = t.y;

                v.texCoord.set(t);
            }
            else
                v.texCoord = new Vector2f(0,0);

            v.normal = norm.get(faces.get(i).normalID - 1);

            vertices.add(v);
        }
    }

Ooops that t.y = t.y stayed in the code, I wrote t.y = 1f - t.y to flip the image on the y-axis. The texID's value is 0 by default, so I can check if there is no tex coords for that vertex.

It is not a cube, it's a sh*tty hallway, just made something to try the loader. Here is how it looks like http://i.imgur.com/sWXw7Lp.png
