It' very nice!! I would like to make the same work..do you know how can i render my face on it??
Sure, you can use LOOXIS' Faceworxs to generate your own OBJ file (with two pictures of your head) and then use Pepakura designer to unfold it. Or if you just want to replace the texture, you can generate it with Faceworxs and change the texture in pepakura designer. The Faceworxs' files are also included in the zip for further reference.
