Hello everyone,

First of all, I am new using processing. I am just trying to see a 3D model in the screen using loadShape();

I used blender to export an .obj file (the monkey model), and I saved it in the same folder of the processing sketch. This is the code I used to load the model, but anything happens:

PShape modelo;

void setup() {  
size(1920, 1080);  
modelo = loadShape(“3D\_Model.obj”);  
}

void draw () {  
background(0);  
shape(modelo);  
}

I just get this error:

Unsupported format: 3D\_Model.obj  
java.lang.NullPointerException: Cannot invoke “processing.core.PShape.isVisible()” because “shape” is null  
at processing.core.PGraphics.shape(PGraphics.java:4124)

Thank you for your time,  
Almudena.

UPDATE: I realized it was a scale problem.
