Hello,  
I am trying to load in a model with a texture in processing. I managed to load in the shape itself, but even after applying a texture to it the model is just fully black.

I followed the setTexture() example with the globe but it doesn’t seem to work for me.

Here is how the code looks like:

```auto
PShape well;
PImage img;

void setup() {
  size(800, 800, P3D);
  lights();
  well = loadShape("Well.obj");
  img = loadImage("wellTexture.png");
  
}

void draw() {
  background(255);
  well.setTexture(img);
  textureMode(NORMAL);
}

```

Don’t you need shape(well); ?

I figured I’d only include the lines related to the textures but this is how it’s drawn

```auto
  pushMatrix();
  translate(width/2, height/2+150, 0);
  rotateX(PI+PI/8);
  rotateY(z);
  scale(100);
  stroke(255);
  shape(well, 0, 0);
  popMatrix();

```

This belongs in setup ()

lights () command must be at beginning of draw()  
after background ()

The following code runs without error on my system (I used an old .obj file from another project):

```auto
PShape well;
PImage img;

float z;

void setup() {
  size(800, 600, P3D);
  well = loadShape("well.obj");
  img = loadImage("well.png");
}

void draw() {
  background(255);
  lights();
  well.setTexture(img);
  translate(width/2, height/2 + 100, 0);
  rotateX(PI+PI/8);
  rotateY(z);
  scale(10);
  stroke(255);
  shape(well, 0, 0);
  z += 0.02;
}

```

Make sure that you enclose the _.obj_ and _.png_ files in a ‘data’ folder inside of your sketch folder.

**Output:**
