Collada file in OpenFrameworks

Dear all,

I’m a quite a beginner in using OpenFrameworks. I’m trying to write a simple piece of software able to load a Collada file. The file includes the 3d model, lights, texture, material, shader info and so on. In particular the model is related to a transparent 3d water drop.

I use ofxAssimpModelLoader to load the .dae file, but the results I get is not a transparent 3d water drop, but a solid blue 3d drop.

Here is the code:

void ofApp::setup(){
ofSetVerticalSync(true);
model.loadModel(“O3_Cina_Drop_03.dae”, true);
autoRotate = 0;
mesh = model.getMesh(0);
texture = model.getTextureForMesh(0);
material = model.getMaterialForMesh(0);
}

//--------------------------------------------------------------
void ofApp::update(){

float stepRotate = 0.05;
autoRotate = autoRotate + stepRotate;
if (autoRotate >= 360)
    autoRotate = 0;
distance = float(ofGetMouseY())/float(ofGetHeight());

interactRotate = ofGetMouseX();

}

//--------------------------------------------------------------
void ofApp::draw(){
ofBackground(255, 255, 255);

ofEnableDepthTest();
ofEnableLighting();

//model.setPosition(ofGetWidth()/2, (float)ofGetHeight()/2 , 0);
ofTranslate(ofGetWidth()/2, (float)ofGetHeight()/2, 0);
ofScale(distance);
ofRotateYDeg(autoRotate);
ofRotateYDeg(interactRotate);

light.enable();

texture.bind();
material.begin();
model.drawFaces();
material.end();
texture.unbind();

light.disable();

ofDisableDepthTest();
ofDisableLighting();

}

Here you can find the xcode project:

Any help is welcomed.
Thank you
