i'm going nuts. i've tried with both
var bmat=new BitmapMaterial(Cast.bitmap("checker"),{smooth:true});
var bmat:IMaterial = new BitmapMaterial(generateFromLib("checker"));
var mat:Dot3BitmapMaterial=new Dot3BitmapMaterial
(bmat,mapgen.normalmap);
(not at the same times)
and have for seconde bmat this error
1067: Implicit coercion of a value of type away3d.materials:IMaterial
to an unrelated type flash.display:BitmapData.
