Can't set Shade GOURAUD on imported Obj models

Question

Hi,
I'm importing an obj model, but I can't get the shading model to be Gouraud. It's always flat.
Here is a short code snippet where I try to make the model use Gouraud shading:
ObjectFile objectFile = new ObjectFile();
Scene scene = null;
try {
scene = objectFile.load(filepath);
(...) // catch block
Hashtable allReferences = scene.getNamedObjects();
Enumeration enumeration = allReferences.keys();
while (enumeration.hasMoreElements()) {
String key = (String) enumeration.nextElement();
Appearance appearance = new Appearance();
ColoringAttributes coloringAttributes = new ColoringAttributes();
coloringAttributes.setShadeModel(ColoringAttributes.SHADE_GOURAUD);
appearance.setColoringAttributes(coloringAttributes);
Material material = new Material();
material.setDiffuseColor(1f, 1f, 1f);
appearance.setMaterial(material);
if (allReferences.get(key) instanceof Shape3D) {
Shape3D ref = (Shape3D) allReferences.get(key);
ref.setCapability(Shape3D.ALLOW_APPEARANCE_OVERRIDE_WRITE);
ref.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
ref.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
ref.setCapability(Shape3D.ALLOW_APPEARANCE_OVERRIDE_READ);
ref.setAppearance(appearance);
Thanks in advance

Answer 1

I think this is the culprit:
3) check the key of the imported file with a software instrument, and switch the project's key accordingly
If the "follow tempo & pitch" box is checked, this might change the sample's pitch and throw GB off.
Try to determine the sample's key before you import it, set the GB project's key accordingly, and then import the sample. That should assign it the correct key!
