Chris,
if you want to trace some bug you can dirt your hand in the
Object3DLoader class, in order to make some trace..
Important:
does it happen when you load a file displayed locally ???
Your code seems correct...
but they are some strange things:
when you call
var obj1:Mesh = ObjectContainer3D(e.loader.handle).getChildByName
("DemoPlayer") as Mesh;
I don't see to wish Object3D you are making reference to :
for now only the e.loader.handle is named "DemoPlayer", named here :
max3ds.handle.name = 'DemoPlayer';
max3ds.handle and e.loader.handle are the same...
does it make sens to you ?
