Thanks for the quick reply Fabrice. I did actually know that and the
following files are all in the same folder - neutral.obj, neutral.mtl,
neutral_skin_hi.jpg, etc.
In my neutral.obj file I have the following line,
mtllib neutral.mtl
And in neutral.mtl I have,
newmtl Texture3
Ns 20
d 1
illum 2
Kd 0.7 0.7 0.7
Ks 0 0 0
Ka 0 0 0
map_Kd neutral_skin_hi.jpg
It seems to me that the files and the locations are all correct and I
can open the OBJ in other viewers such as GLC Player with no problem
too. So the problem must be in my code I think but I can't see
anything wrong compared to the examples I've seen. I've pasted the
relevant sections below.
private function loadMyObjFile (url: String): void
{
var loader: Object3DLoader = Obj.load (url, {autoLoadTextures: true,
bothsides: false});
loader.addOnSuccess (onLoaderSuccess);
view.scene.addChild (loader);
}
private function onLoaderSuccess (e: LoaderEvent): void
{
headObj = (e.loader.handle as ObjectContainer3D).children[0];
headObj.x = headObj.y = headObj.z = 0;
camera.target = headObj;
addEventListener (Event.ENTER_FRAME, onEnterFrame);
}
The only other possibility I can think of is that I'm working with
Away3D 2.3.3 and FP9. Do I need to upgrade to Away 3.3.3 and FP10?
Thanks,
Richard.
PS The software that exported the model is called FaceGen.
