Hi,
I try to convert an animation that i done with away3.6 to away3d 4.
To simplify my animation concept,
it’s like a door with 2 movie material, one on each side.
First : the AnimatedBitmapMaterial size
if i directly use my movieclip in my animatedBitmapMaterial declaration
i have the following error
Error: Invalid bitmapData! Must be power of 2 and not exceeding 2048
...ok normal…so i transform my movieClip to fit the size of 400x400 (200x400 before), but i have the same error…
Do you have an idea on what’s going on ?
When using animatedBitmapMAterial, perhaps it could be a very nce feature if it can be resize by power of 2 automatically…
Second : plane back side
I didn’t find how to setup a different material on the backside of a plane in away 4…
thanks for your help

Power of two does not mean that something is dividable by two.
Power of two means: 2, 4, 8, 16, ..., 256, 512, 1024…
And it seems as if flash (or the new version of it, not sure) does only take textures in that format as input for 3D. I don’t like that, either 
So, in your example, a 256x512 texture should work.

Thanks to you for yopur help..
i ‘m a little bit disappointed that this is so complicate…
@Jan D
thanks, a movie clip sized 256x512 work well…but very complicate to transform all my clip in power of two…
but it’s not your fault
@inSertCode
i have well clone the plane geometry, but how to add a new material to it ?
thanks

_plane.subMeshes[0].material = _material1; //for the first sub-object
_plane.subMeshes[1].material = _material2; //for the second sub-object
...and so on…
ps. and don’t forget to reverse the normals of the cloned plane if you are using lights.

thanks four your help…
but this doesn(t work for me…don’t know what going wrong.. isee only the front material
var step1LeftFrontMat:AnimatedBitmapMaterial = new AnimatedBitmapMaterial(step1Left,false,false,0,null);
var step1LeftBackMat:AnimatedBitmapMaterial = new AnimatedBitmapMaterial(step1LeftBack,false,false,0,null);
var leftPlane:Plane = new Plane(null,200,400,1,1,true)
var backPlane:SubGeometry;
backPlane = leftPlane.subMeshes[0].subGeometry.clone();
leftPlane.geometry.addSubGeometry(backPlane);
for (var i:int = 0; i < leftPlane.subMeshes[1].subGeometry.numVertices * 3; i++) {
if(leftPlane.subMeshes[1].subGeometry.vertexNormalData[i] == 1){
leftPlane.subMeshes[1].subGeometry.vertexNormalData[i] = -1;
}
}
leftPlane.subMeshes[0].material = step1LeftFrontMat
leftPlane.subMeshes[1].material = step1LeftBackMat
thanks
