Greetings, I'm using version processing 1.5 under Ubuntu 12.10  with 64bit with libraries: NyARToolkit, GSVideo.

I import a .3ds with mri3ds library, however when I load it throws the following message: Cameras: 0 Lights: 0 and the screen goes black.
Annex the source code:

 //libreria para 3d
import mri.*;
import codeanticode.gsvideo.*;
import jp.nyatla.nyar4psg.*;
import processing.opengl.*;
import javax.media.opengl.*;


GSCapture cam;
V3dsScene vscene;
NyARBoard mark1;

/************************************************************/

void setup() {

size(640,480,OPENGL);

colorMode(RGB, 100);

cam=new GSCapture(this,width,height);

mark1=new NyARBoard(this,width,height, "camera_para.dat", "patt.hiro", 80);

mark1.gsThreshold=120;

mark1.cfThreshold=0.4;

//libreria de 3d
try
{
vscene = new V3dsScene(this,"mono.3ds");//carga el archivo 3ds
vscene.useMaterial( true );//habilita las texturas

} catch( Exception e )
{
println( e );
System.exit( 0 );
}
//fin de libreria 3d

}

/********************************************************************************************/

void draw() {

if (cam.available() !=true) {
  return;
}
cam.read();


hint(DISABLE_DEPTH_TEST);
image(cam,0,0);
hint(ENABLE_DEPTH_TEST);


  if(mark1.detect(cam)){
 
    PGraphicsOpenGL pgl = (PGraphicsOpenGL) g;
    mark1.beginTransform(pgl);
  
    //TRABAJAR AQUI//
   
    /*
    //imagen plana
    fill(250,0,0);
    rect(-25,-25,50,50);*/
  
    /*
    //cubo 3d procesing
    translate(0,0,30); // trasladar(X,Y,Z)
    rotateY(0);
    box(40);//box(width/ancho, height/alto, depth/profundidad) o box(size/tamaño)
    */  
  
  
   //objeto 3d exportado
    scale(2);
    rotateX(-1.5);//posiciona el objeto en vertical
    rotateY(0);
    rotateZ(-0); 
    vscene.draw();
 
 
    mark1.endTransform();
 
  }

}


The .3ds file I'm generating with Blender 2.65. Please your comments and suggestions.
