No worries, I just try help you by showing you some solutions.
Never said you must use my code, even if by using Away you do use some
of it already :))
Once you have located a Mesh object, to apply a new material to it,
just do: mesh.material = new SomeMaterial();

You are right it's something I have done ... didn't mean to offend by
not using code ...
It gave all false because I was being fancy with the traces doing:
trace("Is obj1mesh a mesh?"+obj1mesh is Mesh);
and should have been
trace("Is obj1mesh a mesh?"+(obj1mesh is Mesh));
Now I see the "parsing" ... thanks for help and the code which I will
impliment.
Any advice on getting texture swapping done on an .obj file?
tried:
for ( var j : Number = 0; j < obj1mesh.faces.length; j++ ) {
obj1mesh.faces[j].material = texture3;}
popped error on use:
TypeError: Error #1034: Type Coercion failed: cannot convert
Test67_texture3$ to away3d.materials.ITriangleMaterial.
for ( var j : Number = 0; j < obj1object3d.faces.length; j++ ) {
obj1object3d.faces[j].material = texture3;
}
failed on compile:
1119: Access of possibly undefined property faces through a reference
with static type away3d.core.base:Object3D.

I do not see entire code here, but I will have here to presume, you
override or do something wrong.
because if handle is a valid Object3D, if your object is correctly
displayed on screen, then it's either a Mesh or an ObjectContainer3D.
so if you do not want use the code I gave you on previous reply
I suggest you just new AS3Exporter(e.loader.handle, "classname",
"packagename"); in the loadedSuccess method.
then you import this class and just do var class:Class = new Class();
then you can acess all meshes by
class.meshes --> array of meshes
class.containers --> array of ObjectContainer3D

Let me know when I'm getting close to being kicked out of group LOL
I appreciate the explaination, Fabrice, thank you ... however ...
I must have one really screwed up .obj ... all traces return
false ...

Hear me out ...
obj1 = Obj.load("assetts/teapot_1.obj",
{material:"teapot_1.jpg"}); ->
loads fine and renders fine
obj1object3d = e.loader.handle; -> I assume this get's the handle to
obj1
obj1mesh = (obj1object3d as ObjectContainer3D).children[0]; -> get's
mesh
obj1mesh = (obj1object3d as Mesh); -> pops error so assume
ObjectContainer3D and use line above
after lines above call traces:
trace(obj1 is Mesh); -> "false" (makes sense)
trace(obj1object3d is Mesh); -> "false" (makes sense)
trace(obj1mesh is Mesh); -> "false" (does NOT makes sense)
trace(obj1 is Object3D); -> "false"
trace(obj1object3d is Object3D); -> "false"
trace(obj1mesh is Object3D); -> "false"
trace(obj1 is ObjectContainer3D); -> "false"
trace(obj1object3d is ObjectContainer3D); -> "false"
trace(obj1mesh is ObjectContainer3D); -> "false"
What in the world does it imply if every single trace is false!?!?!?
Every single variable above is called out private var ...
Sorry be such a pain dude but things aren't jiving ...

Hi Joseph,
the children array is a property of an ObjectContainer3D.
but depending on the model structure, it can be that the child 0 is
also of the same type.
simple traces as trace(mymodel is Mesh), is ObjectContainer3D
etc...
can help you parse your model.
if you however seek a more generic option consider codes like this:
loadedsuccessEvent (e:LoaderEvent)
parse(e.loader.handle);
private function parse(object3d:Object3D):void
{
if(object3d is ObjectContainer3D){
var obj:ObjectContainer3D =
(object3d as ObjectContainer3D);
for(var i:int
=0;i<obj.children.length;++i){
if(obj.children[i] is
ObjectContainer3D){
parse(obj.children[i]); --> we go deeper
} else if(obj.children[i]
is Mesh){
doSomething( obj.children[i]); --> do something with the Mesh
object
}
}
} else if(object3d is Mesh){
doSomething( object3d as Mesh); -->
do something with the Mesh
object
}
}

The only problem is I have never been able to get
object.children.length to work without an error.
I've tried it on the obj loader:
var obj1:Object3DLoader = Obj.load("assetts/teapot_1.obj");
trace(obj1.children.length);
and it results in child.length of 1 ... not sure what that implies
for
just the loader ...
tried grabbing the handle and then doing it:
obj1object3d = e.loader.handle;
trace(obj1object3d.children.length);
1119: Access of possibly undefined property children through a
reference with static type away3d.core.base:Object3D.
and tried converting to mesh:
obj1mesh = (obj1object3d as ObjectContainer3D).children[0];
trace(obj1mesh.children.length);
1119: Access of possibly undefined property children through a
reference with static type away3d.core.base:Mesh.
I changed code (since only have 1 child apparently) to:
for ( var j : Number = 0; j < obj1mesh.faces.length; j++ ) {
obj1mesh.faces[j].material = texture3;}
and error popped:
TypeError: Error #1034: Type Coercion failed: cannot convert
Test67_texture3$ to away3d.materials.ITriangleMaterial.

just try this one:
var texture1 : BitemapFileMaterial = new
BitmapFileMaterial( yourURL);
for ( var i : Number = 0; i < object.children.length; i++ ) {
for ( var j : Number = 0; j <
object.children[i].faces.length; j++ ) {
object.children[i].faces[j].material =
texture1;
}
this probably should work.
