I'm working with Opengl ES 2 on iphone and right now I am trying to get my textures working on my objects. I'm using .obj files and all the data in them are correct. I have written a parser myself to retrieve all data, I convert it to static arrays in C. I discard the material properties for now, only getting the image path from the .mtl files manually.
I have an object with 336 triangles, making this non-trivial to observe, with appertaining vertices, vertex faces and texture coordinates (u,v).
Passing all data into the shaders, the resulting image is this:

But it should look like this (Displaying it in an object viewer). Please ignore the material properties.

Using this image as a texture:

I'm thinking it might have to do with texture coordinate faces ? It is defined in my .obj file, and I'm not using them at all. In books and tutorials I have not found anything concerning this.
