animatedBitmapMaterial generates and stores bitmapdatas from movie
frames
at runtime the instances are swapped. Runs at same speed at regular
bitmapMaterial.
its not suitable for this case.

more of a crossfade really, fading 1 out and fading the other in.
but..
am calling the material via:
var testMovie:MovieClip = new testTransform() as MovieClip;
material:MovieMaterial = new MovieMaterial(testMovie,
{autoplay:false,loop:false});
where as
material:AnimatedBitmapMaterial = new
AnimatedBitmapMaterial(testMovie,{autoplay:false,loop:false});
when using AnimatedBitmapMaterial gives me the following error :
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

oh its just a fade in?
if so, just make a movieclip with 2 containers, load the 2 images
and just play mc
if you pass this mc to moviematerial, set autoupdate to false
and just call update when you play your mc fade timeline.

in my case I would have 243 bitmaps to tween and thus 486 if
tweening from 1 to the other, do you reckon this would have a
massive performance hit and most probably best to use preRender in
a movie material?

if its a vector material, just tween colors using rbg and set
color value to material
if its a bitmapdata, just tween factors and apply colortransform
accordingly
if you prerender, use animatedbitmapMaterial or indeed
moviematerial

Dear All,
Is there a way to transform the color / material of an object. I
can switch materials quite easily but would like a transition..
I have been playing the Tweener to get the job done but
_brightness does not seem to be feature of
materials.BitmapMaterial..
what is the easiest way, is it to cheat and do all the
transitions in a SWF and then just apply the material as a
MovieMaterial and then control the movie use play and stop()...
or can I use a Tweener class to crossfade the material? ie
transform the bitmapData
??
any thoughts
