Hi! I wondering if you need to do something special with the vertex data and index data loaded from the OBJ file, to make it appear on screen? I have done a test in the code to specify the data directly in the code instead of loading it from an OBJ file. This to see if it looks ok. for instance: This is just an example so you get the idea of my problem float vertices2[] = {0.004520f, 0.000000f, -0.363459f, 0.179520f, 0.000000f, -0.315091f, 0.004520f, 0.000000f, -0.002436f, 0.004520f, 1.390251f, -0.363459f, 0.003921f, 1.528259f, 0.001508f, 0.179520f, 1.390251f, -0.315091f }; short indices[] = {1, 2, 3, 4, 5, 6}; Later in the "Draw" method I try to draw the object on the screen. Using glVertexPointer and glDrawElements. gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertices2); gl.glDrawElements(GL10.GL_TRIANGLES, 6, GL10.GL_UNSIGNED_SHORT, indices); The problem is that I can see something on the screen but it is absolutely not what should be there. If I hard code the data of a Penguin, it's not a penguin I see on the screen. What am I doing wrong here? Do I need to do something with the loaded data from the OBJ file before sending it to the vertex array etc? Thanks
