well, the materialLibrary will be cloned along with everything else, so it's
very easy to loop through all the materials used in a cloned object. The
other thing is you seem to be using the clone method incorrectly, and in
this particular instance i would use the similarly titled "cloneAll()"
method which duplicates geometry as well as mesh data:
this["floor"+i] = floorGab.cloneAll();
var matLib:MAterialLibraray = this["floor"+i].materialLibrary;
for each (var matData:MaterialData in matLib) {
if(matData.material is ColorMaterial)
matData.material = new ColorMaterial((matData.material as
ColorMaterial).color);
}
this will reset the material property on all cloned faces to the same
appearing ColorMaterial, but with a different ColorMaterial instance. Then
when your rollover event is triggered, resetting the color using the
material grabbed from the cloned materialLibrary should not affect the
original objects materials, or any other clones
