The Materials should not be scale to fit this plane.
But it looks like only 1 tile here.
var materia : BitmapMaterial = new BitmapMaterial((new _sceneTexture() as Bitmap).bitmapData,true,true); materia.specular = 0.2; materia.specularColor = 0xffffff;
var plane:Plane = new Plane(materia, 1000, 1000, 100, 100); plane.rotate(new Vector3D(1, 0, 0), 90); _view.scene.addChild(plane);

I think you think that building a Plane with segmentsW > 1 and segmentsH > 1 will automatically create a plane with repeating texture coordinates, but it won’t. It just creates a plane existing of (segmentsW+1)*(segmentsH+1) vertices where the texture coordinates are spread between 0 and 1. For a repeating effect you should have texture coordinates that are spread between 0 and 2 (for repeating it twice) or higher (for more repeats). Afaik you have to assign these yourself (I haven’t done this before so I can’t directly tell you how). Hope this helps some though.

Set the scaleU and scaleV of your sub-geometries (myPlane.geometry.subGeometries) to something larger than 1. Then make sure that whatever material you are using has animateUVs set to true. That will allow you to tile bitmaps over a surface.

Thanks very much, it works. I added plane.geometry.scaleUV(10);
var plane:Plane = new Plane(materia, 1000, 1000, 100, 100); plane.geometry.scaleUV(10); plane.rotate(new Vector3D(1, 0, 0), 90); _view.scene.addChild(plane);
