Working code:

```auto
PShape mobius;
PImage txtr;

void setup()
  {  
  size(500, 500, P3D);
  txtr = loadImage("http://learningprocessing.com/code/assets/sunflower.jpg");
  mobius = loadShape("moebius.obj");
  mobius.setFill(color(255)); // Brigthens the texture
  mobius.setTexture(txtr);
  }

void draw() 
  {
  background(255);
  translate(width/2, height/2);
  lights();
  
  rotateY(mouseX*TAU/width);
  rotateX(mouseY*TAU/height);

  scale(6);
  shape(mobius);
  }

```

And voila!
