Ah,
I think I get what you want.
Loading the material in the second step does not work for me.
I've tried it a while time ago.
My solution, that probably also works for you, was to give the object a
simple ColorMaterial when loading and changed this one to
any BitmapFileMaterials I needed later.
When loading an object without parsing an material property
in the parameter object causes, that the objects does not apear
in the scene anyway, even you add a material later. Don't know why,
but again, the solution worked for me in this case.

Hi Roland,
Thanks for the response.
I see what you are getting at, however, does this work for a
BitmapFileMaterial?
Let me try again to explain what I'm doing.
I have 1 .obj file (i.e. teapot_1.obj) ...
I have several different bipmap files (i.e. teapot_1.jpg,
teapot_2.jpg) that I can swap around when I load initially (removed
texture & mtl info in .obj file) as such:
= Obj.load("assetts/teapot_1.obj",{material:texture3});
or
= Obj.load("assetts/teapot_1.obj",{material:texture2});
or
= Obj.load("assetts/teapot_1.obj",{material:texture1});
They all load fine because I coordinated the UV mapping for all to the
object.
Is there a way to break apart the Obj.load such that I load the obj
first:
= Obj.load("assetts/teapot_1.obj")
and then load textureX (i.e. teapot_1.jpg) with seperate "command"?
I thought I saw a basic example where it was done in 2 steps but I
can't find the example now ...

Hi Joseph,
you get an errror because Object3D does not have any material
property.
To swap materials on importedobjects you have to parse through all
its
faces
and set the material of the faces to the one you like to have.
Here is a litte snippet for you:
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 = new
ShadingColorMaterial( c );
}
}
In this case "object" will be your Object3D instance.
Hope this works. If not, try ObjectContainer3D instead of Object3D.

Hello,
Been looking at source code for (Basic09_BitmapMaterialExplorer.as).
Want to swap textures back and forth on an .obj ... not quite
working,
though ...
Flex framework brought into project library ... CS4, away3d
3.3.3 ...
Import relavent away3d classes:
import away3d.core.utils.Cast;
import away3d.materials.BitmapMaterial;
I embed a couple of textures:
[Embed(source="assetts/teapot_1.jpg")]
public var texture1:Class;
[Embed(source="assetts/teapot_2.jpg")]
public var texture2:Class;
Declare material variables:
private var material1:BitmapMaterial;
private var material2:BitmapMaterial;
Load in .obj:
var obj1:Object3DLoader = Obj.load("assetts/teapot_1.obj",
{material:texture1});
On success grab handle:
obj1object3d = e.loader.handle;
Create new materials:
material1 = new BitmapMaterial( Cast.bitmap( new this[texture1]() as
Bitmap ));
material2 = new BitmapMaterial( Cast.bitmap( new this[texture2]() as
Bitmap ));
On button press simply toggle materials with these calls:
obj1object3d.material = material1;
or
obj1object3d.material = material2;
But get error for the toggle material calls ...
1119: Access of possibly undefined property material through a
reference with static type away3d.core.base:Object3D.
Obviously for a primitive sphere.material works but for Object3D I
have to get it another way ... how would I do that?
BTW, all these things I'm learning I'm compiling into a "Common Noob
Mistakes" to help others as low level as I ...- Hide quoted text -
