this will not work cleanly.
if the image contains blue, it will alter the image creating the noise
you describe.
so using same principle, replace in photoshop/editor the alpha channel
by a given color. Avoid green, since jpg is most destructive in this
color range. preffer a red.
in flash loop on the bmd, and trace a fffff into a black bmd. then
copychannel 1temp bmd to 8 of your destination bmd.
you can automate this from a simple Php loop or even photoshop. (Php
will be like a zillion time faster than Photoshop)

Something else you could consider is doing a little post-processing on
your JPG files - once you've got the JPG loaded, you could get at the
BitmapData and use copyChannels to copy the blue channel into the
alpha channel, thusly:
var tmpBmp = [jpg bitmapdata];
tmpBmp.copyChannel( tmpBmp, tmpBmp.rect, tmpBmp.rect.topLeft,
BitmapDataChannel.BLUE, BitmapDataChannel.ALPHA);
Voila! Blue == transparent without having to export lots of new PNG
files. It might be a little noisy, but that's an artifact of jpeg
compression you'd encounter anywhere you were trying to do something
like this.

Hey Ben
do try again with png in swf and use compression as jpg(set in
library flash
IDE i mean), as i remember png got smaller size in same quality,
btw must
use "save for web" in photoshop for png not just s"ave as" png

PNG are so much larger than JPGs, so I think PNGs won't be
feasible.....I got an item database with almost 10k items....most
with
own mesh in male / female version. The 3ds File is almost 100k each
and the JPG texture 100k again...a PNG would be like 500k I guess.
Any idea what could be done otherwise?
So is there no transparent color-keying at this moment?
Do you think it would be hard to say to the renderer that he should
omit drawing a pixel if it's of a certain color?

Hey Ben
have you tried using a transparent png for the texture? You
should be
able
to achieve the effect you want without any extra trickery - just
have
transparency in your image from the start in place of the blue
color and
you
should be set!

As you seem to be one of the main developer on this project:
Is there any color-keying option to make surfaces transparent?
In my
case blue is defined to be the "transparent color", so I'd like to
omit the drawing there..

i'm afraid so, the maths for resolving a specular component

currently not something i have the time to spend on!

I don't think you can mix those two (normal + specular). If
that's
the
case
there "might" be a way of mixing them by using a Composite

made
of
two seperate materials, but that a hunch and it might not turn
out as
expected...

I've got some a 3d Model which include a standard texture
(diffuse), a
normal map and a specular map.
Now I added some light to the scene.
I used the Dot3BitmapMaterial, with the texture bitmap as
first
parameter and the normal map as the second as described in the
documentation.
I noticed that I can't get some shiny effect on my mode, even
though
there is a shininess component and a specular coefficient.
I use a DirectionalLight3d, but have seen that only ambient
and
diffuse parts of the light are being considered...if I use the
specular part, the whole model stays dark. With
PhongBitmapmaterial
is
seems ok, but I can't include my normal map details and it
looks
kinda
weird.
Any idea how I can get the normal map working with some
shininess?
Or do I just use the wrong material type?
Thanks
