I think you missed the idea:
make a textfield
add changed event to textfield
in your handler add something like
private function onChangedTextfield(e:Event):void
{
var index:int = Math.floor(Number(mytextfield.text));
if(index >mesh.faces.length-1 )
return;
mesh.faces[index].material = someOtherMaterial;
}
now type 0 in your textfield, then 1, then 2
this way you see which face is altered
since it can be tedious iof model is hudge, you probably undertstand
now why a slider or numerical stepper would be handy
here for instance an example where i use a scrollbar to identify a
face and in this case assign the index of the face for FaceLink

Fabrice,
I have no idea how to do what you mentioned in your post.
My understanding is that after I load the 3d model into away3d, I have
no way of knowing which face is "face A" which is coupled with
"material A", which face is "face B" which is coupled with "material
B". Now even I add scrollbar or textfield to the faces, I still don't
know which is which.
Please shed more light on this, I am very confused,
Thanks a lot,
Ron

just make a simple scrollbar, numerical stepper or some textfield and
couple with a setMaterial handler.
like said before, it might be in case of complex shape more easy to
export as separate meshes.
but since its a box, it might be easy to note at dev time from 0 to
30
its side one, from 31 to 60 side two....

Thanks, Fabrice,
But how do I know which face is face[0], which face is face[1] in my
mesh?

if your model have 4 textures applied, you will not be able to
apply
as Mesh.material
you will have to loop over the Mesh.faces and set the material per
face.
Mesh.faces[i].material = material;
if the model is (too) complex
you are better off splitting the geometry in more meshes with
unique
material in your editor.

Hello,
Guy, I've been working on this for days, but I still couldn't
figure
out how to do this. There are couple posts about this topic a
while
back, but they didn't help my problem.
Ok, here's what I did. I made a hollowed box in google sketchup,
and I
used different materials(.jpg file) for some surfaces of the
hollowed
box. My model was exported as .dae file. and I loaded this .dae
file
in away3d. The .jpg files for material are seperated from the .dae
file. Now I just don't know how to get the material into the 3d
model.
If there was just one material, it's easy, simply add the
material.
but now I have 4 materials, how do I add the materials and make
sure
materials match the surfaces where they are supposed to apply to?
Many thanks,
Ron
