I have a generic 3d model containing different parts of the head (in .obj format). From the obj file, I extracted just the front face part like the figure shown below (by deleting other parts of the head from obj file). Using the UV unwrapping method, I created the shape map/position/geometry map from the 3d face and then used 2D to 3D conversion to reconstruct the 3d face. But the reconstructed face is coming out like this. I couldn't make out the reason as to why this is happening. Please find the attached edited obj screenshot(right most) and results I am getting after each step - (shape map (middle), and reconstructed obj (left most) from shape map)
