i see... how silly of me thanks you very much!! now i finally get to see bothsides but it was applied on every meshes i want to apply it on certain meshes @_@ this is the code that i used
for each (var object:Mesh in model.children) {
if (object.name.indexOf("wing") != -1)
object.ownCanvas = true;
object.alpha = .5;
object.bothsides = true;
}
